What Is The Difference Between Fire Valve And Ordinary Valve?

Fire valves are important accessories for control on industrial and construction pipelines. The fire valve is composed of three parts: the valve body, the opening and closing mechanism, and the valve cover.
Commonly used fire valves include gate valve, globe valve, throttle valve, instrument valve, plunger valve, ball valve, butterfly valve, check valve, remote control float valve, solenoid valve, pressure reducing valve, filter, wet alarm valve, etc.

Ordinary butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. Butterfly valve that can be used for on-off control of low-pressure pipeline medium means that the closing member (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening. A valve with a closed, butterfly valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting off and throttling on the pipeline.

Fire butterfly valve
The fire signal has the advantages of simple structure, reliable sealing, easy opening, long service life and convenient maintenance. Therefore, it is widely used in various pipelines of water supply and drainage, building fire protection and other systems, especially in fire protection pipelines.
The material of fire-fighting butterfly valve is different from that of ordinary butterfly valve. One feature is that most of them use red coating, which is a big difference intuitively. And most of them are made of high temperature and fire resistant materials, such as cast iron, cast steel and nickel aluminum bronze and so on.

Fire butterfly valves are widely used in coal chemical, petrochemical, rubber, paper, pharmaceutical and other pipelines as medium shunting and confluence or flow direction switching devices.
