Valve type

Valves can be divided into straight stroke valves, angular stroke valves, automatic valves, special valves and other categories.

 

Straight stroke valves can be divided into gate valves, globe valves, plunger valves, diaphragm valves, and pipe clamp valves. The gate valve can be divided into a knife gate valve, a parallel gate valve and a wedge gate valve; the globe valve is further divided into a through-cut valve, an angle-type stop valve, a three-way stop valve, a Y-type stop valve, and a needle-shaped stop valve; the diaphragm valve can be divided into 堰Diaphragm valve, angle diaphragm valve.

 

The angular stroke valve can be divided into three types: ball valve, butterfly valve and plug valve. The ball valve can be divided into a lift rod type ball valve, a floating ball ball valve, a fixed ball ball valve, a reduced diameter ball valve, a pipeline ball valve, a multi-pass ball valve; a butterfly valve can be divided into a middle line sealing butterfly valve, a single eccentric butterfly valve, a double eccentric butterfly valve, a triple eccentric butterfly valve; a cock The valve can be divided into a cylindrical plug valve and a tapered plug valve.

 

Automatic valves can be divided into safety valves, steam traps, check valves, pressure reducing valves and so on. Safety valves can be divided into heavy hammer type, spring type, pilot type and additional load type. Steam traps can be classified into mechanical type, thermodynamic type, and thermostatic type. Check valves can be divided into swing type, lift type, double flap type, axial flow type and additional load type. The pressure reducing valve can be divided into a film type, a piston type, a bellows type, and a pilot type.

 

There are many special valve types, including gas pressure regulating valve, breathing/exhaust valve, nitrogen sealing valve, pump protection valve, vacuum valve, cryogenic valve, lining valve, blind valve, mirror/blind valve, pigging valve, Sampling valves, tank bottom valves, food safety valves, non-metallic valves, alloy valves, axial flow valves, nuclear valves, regulating valves, hydraulic control valves, etc.
