VSP-3501-316 pneumatic valve VERSA

According to the direction of fluid flow in the pipeline, if only one direction of fluid flow is allowed, such valves are called one-way control valves, such as one-way valves, shuttle valves, etc; The control valve that can change the direction of fluid flow is called a directional valve, such as commonly used two position two-way, two position three-way, two position five way, three position five way, etc.

(2) According to the control method, it can be divided into solenoid valves, mechanical valves, pneumatic valves, and human controlled valves. Among them, solenoid valves can be divided into two types: single and double electric control valves; Mechanical valves can be divided into various types such as ball head valves, roller valves, etc; Pneumatic valves can also be divided into single pneumatic valves and dual pneumatic valves; Manual valves can be divided into two types: manual valves and foot operated valves.

(3) According to the working principle, it can be divided into direct acting valves and pilot valves. Direct acting valves are valves that rely on human or electromagnetic force, and pneumatic force to directly achieve directional requirements; A pilot valve consists of a pilot head and a valve body, with the pilot head piston driving the valve stem inside the valve body to achieve directional change.

(4) Valves can be divided into 2way and 3-way valves based on the working position of the reversing valve stem.

(5) According to the number of air holes on the valve, it can be divided into 2port, 3port, and 5port valves
