Valve options KLP 1
All valves KLOP-1 have a channel type of development. They are equipped with two flanges and external actuators. different types. > KLOP-1 valves with a round section can have nipple joints. Such valves are called nipple.
Normally open (NO) valves KLOP-1 are presented in several types of modifications. They can be equipped with an electromagnetic drive with a thermal lock capable of withstanding temperatures up to 72 ° C, or an electromagnetic drive without a thermal lock. Also, KLP valves can be equipped with BELIMO electromechanical actuators with thermal locking devices designed for temperatures up to 72 °C, or electromechanical actuators without such devices, and spring actuators with thermal locks that can withstand temperatures either up to 72 °С or up to 141 °С . 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, having small and medium dimensions, are equipped with an electromagnetic actuator. Large dampers KLOP-1(90) and KLOP-1(60) have BELIMO reversing actuators of the BLE or BE type or BELIMO electromechanical actuators equipped with BF or BLF return springs without TRU.
Installation of valves KLP 1
KLOP-1 valves retain their full performance when installed in any position. The design and further installation of such valves are made in accordance with calculations based on the availability of the valve for operation and accessibility to all devices that are located inside it.
KLP dampers are designed 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 condensate on the valve flaps are completely excluded. If the environment surrounding the KLP 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 dampers are designed mainly for air ducts of large cross section.
