Features and uses:

F452-1.0K electromagnetic type gas safety shut-off valve not only overcomes the shortcomings of currently used electric shut-off valve shut-off valve, such as slow speed and complicated control, but also can immediately cut off the gas when power is off to ensure production safety.

F452-1.0K explosion-proof electric actuator type quick gas safety shut-off valve, more suitable for places requiring explosion-proof and system for the dual-supply, never power outage production user system.

This product is mainly composed of electromagnetic type, explosion-proof actuator type starter and butterfly valve with good sealing performance. It has the advantages of simple structure, convenient operation, reliable operation, fast cutting speed and good sealing performance.

Most industrial furnaces that use coal gas as fuel now use gas burners, and special fans provide combustion air. Most of the furnaces also use air preheaters. In the production process, once the gas or air pressure is too low and the burning nozzle is not working properly, the gas should be cut off immediately and the fan stopped (except in special circumstances). This will ensure production safety without causing the furnace to quickly cool. If the gas is not cut off in time and the gas or air is at a low pressure, it is possible to burn the gas mixture into the duct, or the air enters the gas pipeline. In particular, ducts with preheating devices will form a negative pressure due to temperature drop, which will make it easier for gas to enter the air duct, and then form an explosive mixture in the duct air or in the furnace. When re-igniting, it will often cause explosions. Into an accident. This situation has occurred repeatedly. This product was developed and designed for these situations. It is an indispensable and ideal equipment for industrial furnaces and kiln production using gas as fuel.

Electromagnetic gas safety shut-off valve can also be applied to other occasions with similar requirements.
