Pneumatic cut-off valves have the function of quick cut-off, and have the characteristics of simple structure, sensitive response and reliable action. Can be widely used in petroleum, chemical industry, metallurgy and other industrial production departments. The air source of pneumatic cut-off valve requires filtered compressed air, and the medium flowing through the valve body should be liquid and gas without impurities and particles. Classification of pneumatic cut-off valves: ordinary pneumatic cut-off valves and quick emergency pneumatic cut-off valves.

Valve function and working principle:

Gas emergency cut-off valve is a normally open pulse-triggered solenoid valve, which has the functions of accident self-locking and manual reset.

1. In daily work, the valve is always open, and the solenoid valve coil is in a power-off state, which does not consume electric energy.

2. When the accident happens, the valve coil is energized instantly, which triggers the valve to close quickly and enter the self-locking state. At this time, even if the power supply is cut off, the valve is still in a self-locking state and will not automatically open again.

3. The valve adopts pilot disc, which is easy to open even if the pressure reaches 6bar. The diameter is larger than DN 125, and the lever handle is adopted to make the valve open and close conveniently and quickly.

4, when the staff to deal with the accident, manually open the valve, will resume gas supply. ? Note: According to user's requirements, normally closed emergency cut-off valve can also be provided.

The above introduction mainly considers the consumer's point of view, including the recommendation of brand manufacturers and the working principle of pneumatic cut-off valve. We know that this product is widely used because of its simple structure, sensitive response and reliable action, and there are many trustworthy manufacturers in the market. Although the corresponding prices are quite different, they all seem to be several thousand yuan, so we can divide them according to this standard and screen out a truly trustworthy product.
