Purpose
Fire-prevention normally open (fire-retarding) valves KLOP-1 are designed to block the spread of fire and combustion products through air ducts, shafts and channels of ventilation and air conditioning systems of buildings and structures for various purposes. KLOP-1 smoke and normally closed valves are used as smoke ventilation valves. The valves are used in accordance with the requirements of SNiP 41-01-2008, SNiP 21-01-97* and territorial building codes.KLOP-1 valves cannot be installed in rooms of categories A and B due to explosion and fire hazard. KLOP-1 valves in explosion-proof design are installed in these premises.
Valves are manufactured in rectangular and circular cross-sections.
Fire resistance limit of valves:
CLOP-1(60)
- in normally open (fire retardant) and normally closed modes – EI 60;
- in smoke mode – E 60.
- in normally open (fire retardant) and normally closed modes – EI 90;
- in smoke mode – E 90.
Normally open (NO) valves KLOP-1 are manufactured in various modifications depending on the type of actuator:
- round valves with an electromagnetic drive are manufactured without a thermal lock;
- with BELIMO electromechanical drives (type BF or BLF) in combination with a thermal release device at 72 °C (or without it);
- with spring drive and thermal lock at 72 °C or 141 °C, with or without microswitches.
KLOP-1 valves are operational in any spatial orientation.
Installation
When designing and installing valves in ventilation systems, one should take into account ease of access to the valve drive and maintenance hatches for devices located inside the valve.In large cross-section air ducts crossing the enclosing structures of ventilation chambers with high-capacity fans installed in them, it is recommended to install KLOP-3 valves.
The round valve body is made of galvanized steel.
Execution
View climatic version valves – U3 according to GOST 15150-69. The valves can be installed indoors with ambient temperatures from -30 °C to +40 °C in the absence of direct influence atmospheric precipitation and moisture condensation on the damper.Environment must be explosion-proof, not containing aggressive vapors and gases in concentrations that destroy metals, paint coatings and electrical insulation.
When installing normally open (fire-retarding) valves outside walls (ceilings), external fire protection must be applied to the edge of the casing protecting the valve drive, and in accordance with the requirements of SNiP 41-01-2008 (clause 7.11.1, Note 1) must provide a limit fire resistance not less than the required fire resistance limit of the barrier.
In accordance with SNiP, valves can be installed from the side of room A. In these cases, valve installation diagrams are depicted “mirror” relative to building structure, that is, the protective casing must be located in the structure or external fire protection on the side of room A.
In accordance with the results of long-term climatic tests of valves carried out for their operating conditions at the interface between media and different temperatures and humidity, this scheme is recommended for macroclimatic regions with a temperate climate.
When installing valves in the external building envelope, additional devices are provided to prevent atmospheric precipitation from entering the valve, for example, louvered grilles, canopies, etc.
For installation in air ducts with a diameter of 100, 125 and 140 mm, instead of KLOP ® -1 valves with tubular or plate transitions, KLOP ® -2 valves of the corresponding diameter without transitions can be manufactured.
Transport valves
The valves have design features that take into account the specific operating conditions at transport facilities and can be used in ventilation and air conditioning systems for railway rolling stock. The valves have been tested for vibration and impact resistance.Valves for clean rooms

Fire-prevention normally open (fire-retarding) valves KLOP®-1 are designed to block the spread of fire and combustion products through air ducts, shafts and channels of ventilation and air conditioning systems of buildings and structures for various purposes. Normally closed valves KLOP®-1 are used as valves for mechanical supply and exhaust smoke ventilation; the valves can also be used as smoke valves. The valves are used in accordance with regulatory requirements. KLOP®-1 valves cannot be installed in rooms of categories A and B due to fire and explosion hazard. In these premises, explosion-proof valves KLOP®-1 or KLOP®-2 are installed.
Fire resistance limit of KLOP®-1 valves (60/90)
In normally open (fire retardant) valve mode:
- when the drive is located on the thermal side - EI 60/90;
- when the drive is located on the side opposite to the thermal effect - EI 60/90;
- when installing the valve on a section of the air duct outside the enclosing
- building structure with a standardized fire resistance limit - EI 60/90;
– in normally closed valve mode - EI 60/90;
– in smoke valve mode - E 60/90.
When deciding on the use of fire dampers, it is advisable to take into account the advantages of the new generation KLOP®-2 valves with improved characteristics (see section KLOP®-2). In accordance with the entry in the NO certificates, KLOP®-1(60/90) valves can be installed both in a fire-resistant building structure (fire barrier) and outside it in the section of a fire-resistant air duct, regardless of the direction of the possible thermal effect on their structure. In accordance with the requirement of clause 6.11 of SP 7.13130.2013, this allows the installation of valves on any side of the fire barrier, regardless of the location of the fire in relation to this barrier. Compliance with the requirement of clause 6.11 is ensured by the presence of a casing that protects the drive of NO valves both when they are installed in a fire-resistant building structure, and when the valves are installed on a section of the air duct outside this structure.
Normally open (NO) valves KLOP®-1 are manufactured in various modifications depending on the type of actuator:
– with an electromagnetic drive in combination with a thermal lock at 72°C (on special order at 93 or 141°C);
– with BELIMO electromechanical actuators type BFL, BFN or BF (for large valves) in combination with a thermal release device at 72°C (on special order at 93 or 141°C);
Normally closed (NC) valves KLOP®-1 are produced with an electromagnetic actuator without a thermal lock or reversible BELIMO actuators of type BLE, BEN, BEE or BE (for large valves). Drive characteristics and electrical circuits their connections are shown on pages 78-83.
KLOP®-1 valves are produced with a rectangular cross-section only of the “channel” type with two flanges. The valve drive is installed outside the housing. The valve body is made of carbon cold-rolled steel and then painted. On special order, the housing can be made of stainless steel. The body and damper of such valves are made of stainless steel (Spanish: “Stainless Steel”), the remaining components and structural elements are made of carbon steel with anti-corrosion zinc coating. The valve flaps are filled with thermal insulation.
KLOP®-1 valves are operational in any spatial orientation. When designing and installing valves in ventilation systems, it is recommended to take into account ease of access to the valve drive and inspection hatches in its body. When installing KLOP®-1 valves in large cross-section air ducts in areas located behind a sharp change in the direction of air flow, for example, behind 90° bends, it is recommended to ensure open position valve flaps in the plane of flow rotation or use KLOP®-3 valves. The type of climatic version of the valves is U3 according to GOST 15150-69. The valves can be installed in enclosed spaces with air temperatures from -30°C to +40°C, where fluctuations in temperature and air humidity are significantly less than outside the building. The environment must be explosion-proof, not containing aggressive vapors and gases in concentrations that destroy metals, paint and varnish coatings and electrical insulation.
Fireproof normally open valves KLOP-1 designed to block the spread of fire and combustion products. Normally closed valves KLOP-1 are used as valves for mechanical supply and exhaust smoke ventilation; the valves can also be used as smoke valves. The valves are used in accordance with regulatory requirements.
KLOP-1 valves cannot be installed in rooms of categories A and B due to explosion and fire hazard. In these premises, explosion-proof valves KLOP-1 or KLOP-2 are installed.
Note: Normally open NO valves KLOP-1(60/90) can be installed both in a fire-resistant building structure (fire barrier) and outside it on a fire-resistant air duct section, regardless of the direction of possible thermal effects on their structures. In accordance with the requirement of clause 6.11 of SP 7.13130.2013, this allows the installation of valves on any side of the fire barrier, regardless of the location of the fire in relation to this barrier. Compliance with the requirement of clause 6.11 is ensured by the presence of a casing that protects the drive of NO valves both when they are installed in a fire-resistant building structure, and when the valves are installed on a section of the air duct outside this structure.

KLOP-1 valves are produced only of the “channel” type with two rectangular cross-section flanges). The valve drive is installed outside the housing. The body of rectangular valves is made of carbon cold-rolled steel with subsequent painting, the body of round valves is made of galvanized steel.
On special order, the housing can be made of stainless steel. The body and damper of such valves are made of stainless steel (Spanish: “stainless steel”), the remaining components and structural elements are made of carbon steel with anti-corrosion zinc coating.
The valve flaps are filled with thermal insulation.
Operating conditions CLOP 1
Valves KLOP-1 workable in any spatial orientation.
When designing and installing valves in ventilation systems, it is recommended to take into account ease of access to the valve drive and inspection hatches in its body.
When installing KLOP-1 valves in large cross-section air ducts in areas located behind a sharp change in the direction of air flow, for example, behind 90° bends, it is recommended to ensure that the valve damper is in an open position in the plane of flow rotation or to use KLOP-3 valves.
The type of climatic version of the valves is U3 according to GOST 15150-69. The valves can be installed in enclosed spaces with air temperatures from -30°C to +40°C, where fluctuations in temperature and air humidity are significantly less than outside the building.
The environment must be explosion-proof, not containing aggressive vapors and gases in concentrations that destroy metals, paint and varnish coatings and electrical insulation.

Non-standard use of the KLOP 1 valve
The main feature of the fire damper KLOP-1 (60/90) is the possibility of application for premises with non-standard requirements. Fire damper KLOP-1 (60/90) can be designed in several versions, for example:
- For work in conditions of high humidity
Such valves can be used on river or sea transport, stationary platforms, which is confirmed by various state-issued certificates. The manufacturing material for such valves is high-quality stainless steel, and their Belimo electromechanical drive is installed in a special casing with high degree protection. - For work in transport
Thanks to design features Fire dampers KLOP-1(60/90), which are intended for use in railway transport, can be installed in ventilation systems and air conditioners. - For work in areas that are particularly demanding on cleanliness
When producing KLOP-1(60) for rooms with high sterility requirements, special stainless steel is used.

Valve options KLOP 1
All KLOP-1 valves have a channel design. They are equipped with two flanges and externally mounted drives. different types. >KLOP-1 valves with a round cross-section can have nipple joints. Such valves are called nipple valves.
Normally open (NO) valves KLOP-1 are presented in several types of modifications. They can be equipped with an electromagnetic drive that has a thermal lock that can withstand temperatures up to 72 ° C, or an electromagnetic drive that does not have a thermal lock. Also, KLOP valves can be equipped with BELIMO electromechanical actuators with thermal closing devices designed for temperatures up to 72 °C, or electromechanical actuators without such devices, and spring actuators with thermal locks that can withstand temperatures of either up to 72 °C or up to 141 °C . In addition, KLOP-1 valves can be equipped with microswitches.
Normally closed (NC) and smoke dampers KLOP-1(90) and KLOP-1(60) are not equipped with thermal locks. Valves of this type, which are small and medium in size, are equipped with an electromagnetic drive. Large valves KLOP-1(90) and KLOP-1(60) have reversible BELIMO actuators type BLE or BE or electromechanical BELIMO actuators equipped with return springs BF or BLF without TRU.
Installation of valves KLOP 1
KLOP-1 valves retain their full functionality when installed in any position. The design and further installation of such valves are carried out in accordance with calculations based on the accessibility of the valve for operation and accessibility to all devices that are located inside it.
KLOP dampers are intended for installation indoors, where the air temperature ranges from -30 °C to +40 °C. They are installed in such a way that direct contact with natural precipitation or the formation of condensation on the valve flaps is completely excluded. If the environment surrounding the CLOP valves contains aggressive vapors or gases, their concentration should not be too high. Otherwise, the aggressive environment will have a destructive effect on the metal from which the KLOP valves are made and on the electrical insulation.
KLOP-3 valves are designed primarily for large cross-section air ducts.
