KLOP-1 valves are manufactured as a fire-retarding valve and smoke removal. Depending on the type and operating conditions, valve housings are produced different meaning fire resistance. Prevents the spread of combustion products throughout the premises of the building through, ventilation ducts and mines.
KLOP-1 valves cannot be installed in rooms of categories A and B due to fire and explosion hazard. KLOP-1 valves in explosion-proof design are installed in these premises.
Fire resistance limit of valves:
Valve KLOP-1(60)
- in normally open (fire retardant) and normally closed modes - EI 60;
- in smoke mode - EI 60, E 60.
- in normally open (fire retardant) and normally closed mode - EI 90
- in smoke mode - EI 90, E 90.
Normally open 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 (or without it);
- 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. When designing and installing valves in ventilation systems, one should take into account ease of access to the valve drive and service hatches for devices located inside the valve.
In large cross-section air ducts crossing building envelopes ventilation chambers with high-capacity fans installed in them, it is recommended to install KLOP-3 valves.
The type of climatic version of the valves is 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 exposure to precipitation and moisture condensation on the damper.
The environment must be explosion-proof, not containing aggressive vapors and gases in concentrations that destroy metals, paint coatings and electrical insulation.
Order examples:
KLOP-1(60)-D-EM(220)-500x500-K - valve KLOP-1 with a fire resistance limit of 60 minutes, smoke, with a 220 V electromagnetic drive, with internal cross-section dimensions 500x500 mm, with a terminal block.
KLOP-1(90)-NO-MV(220)-250(Fl)-N - valve KLOP-1 with a fire resistance limit of 90 minutes, normally open (fire-retardant), with a Belimo electromechanical drive for 220 V, with an internal diameter of 200 mm, flanged, without terminal block.
Fire damper KLOP-1 on the market of domestic fire dampers is, perhaps, one of the most famous and eminent.
Its certification and the development of mass production were carried out in 1999, and the KLOP-1 valve became the first domestic certified fire damper, and the name KLOP-1 became a registered trademark. For some time, the KLOP-1 valve was the only fire damper domestic production. Well-organized marketing and work with the manufacturer design organizations made the CLOP valve popular, often found in project documentation. This probably contributed to the fact that the name KLOP-1 became a household name; you may encounter situations when a customer, applying for valves, says: “I need to buy KLOP-1,” although the specific name of the valve is not indicated in his documentation and the valve CLOP-1 can be replaced with others fire dampers with similar parameters.
The fire damper KLOP-1 is installed in the channels of general ventilation and air conditioning with mechanical draft stimulation. Fire retardant (normally open valves) prevent the spread of fire through these channels, and smoke (normally closed valves) prevent the spread or removal of smoke.
Fire damper KLOP-1 is produced in two modifications:
CLOP-1(60);
CLOP-1(90);
The difference between them lies in the fire resistance limits.
KLOP-1 (60) has a fire resistance limit of 60 minutes (1 hour).
KLOP-1 (90) has a fire resistance limit of 90 minutes (1.5 hours).
The KLOP-1 valve can perform the functions of both a fire-retarding valve (damper in the “normally open” position) and a smoke exhaust valve (damper in the “normally closed” position).
The valve body can be made of either round or rectangular (square) cross-section.
KLOP-1 is intended for installation only in the canal. The drive that transfers the valve flap from the initial state to the operating state is located outside the valve. To control the position of the damper, a special inspection hatch is provided on the valve. It is used when an air duct is connected to the valve on both sides and it is not possible to look inside the already installed valve through the flow section.
The body of the KLOP-1 valve is made of carbon (black) steel, subsequently painted. In this way, KLOP-1 differs from the KLOP-2 valve, the body of which is made of galvanized steel.
A rectangular (square) valve is equipped on both sides with flanges through which it is attached to the ventilation duct.
The round valve can be manufactured either on flanges or for nipple mounting in the ventilation duct.
Fire damper KLOP-1 is equipped with the following types actuators for controlling the valve flap:
Electromechanical drive BELIMO type BF(24), BF(220) or BLF(24), BLF(220) with return spring with supply voltage 24V or 220V;
Electromagnetic EM(220), EM(24) or EM(12) - electromagnetic drive with supply voltage 12V, 24V or 220V;
TZ - spring drive with thermal lock;
TZ(M) - spring drive with thermal lock and microswitches;
When choosing an actuator for fire dampers, you should consider that:
Part 2 Art. 138 Federal Law No. 123-FZ prohibits the use of actuators of the TZ and TZ(M) types on NO fire dampers in Russian Federation.
The use of MV type actuators on NC and smoke valves in the Russian Federation is contrary to clause 7.18 of SP 7.13130.2009.
The price of fire dampers KLOP-1, KLOP-2, KLOP-3, KOM-1, KDM-2 and KLAD-2 are given below.
The price of a fire damper with dimensions different from those indicated in the table is determined on the larger side. For example, the price of a KLOP-1 valve with dimensions 400x200 is determined as the price of a 400x400 valve. The price of a KLOP-2 valve with dimensions 600x350 is determined as the price of a valve with dimensions 600x600, etc.

The valves have a certificate of type approval from the Russian Maritime Register of Shipping and a certificate of approval from the Russian River Register, which allows them to be used both on sea vessels and stationary offshore platforms, and on river vessels. These valves can be installed in rooms with high humidity.
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.
