Product Description
Features and uses:
F452-1.0K type electromagnetic gas safety shut-off valve not only overcomes the current domestic commonly used electric shut-off valve shut-off valve slow, complex control and other shortcomings, but also can immediately cut off the gas when the power is off, to ensure production safety.
F452-1.0K type explosion-proof electric actuator type fast gas safety shut-off valve, more suitable for explosion-proof places and systems for dual power supply, never power production user system.
This product is mainly composed of electromagnetic, explosion-proof actuator starter and butterfly valve with good sealing performance. It has the advantages of simple structure, convenient operation, reliable work, fast cutting speed and good sealing performance.
At present, most of the industrial kilns with gas as fuel use gas burner, and the special fan provides combustion air. Most of the kilns also use air preheating devices. In the production process, once the gas or air pressure is too low, the burner can not work properly, should immediately cut off the gas and stop the fan (except for special circumstances). This can ensure production safety, but not to make the furnace quickly become cold. If the gas is not cut off in time, when the gas or air is low, it is possible to pass through the mixed gas of the burning nozzle, the gas enters the air pipe, or the air enters the gas pipe. In particular, there is a preheating device of the air duct, due to the temperature drop will form a negative pressure, more easy to make the gas into the air duct, and then in the air duct wind or furnace to form an explosive mixture, when the re-ignition will often cause an explosion, resulting in an accident. This kind of situation occurs frequently, this product is formally developed and designed for these situations, and it is an indispensable ideal equipment for the production safety of various industrial furnaces, check valves and kilns with gas as fuel.
Electromagnetic gas safety shut-off valve can also be applied to other occasions with similar requirements.
