A solenoid valve is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold.
The Following are the types:
- Plastic Solenoid Valves
- High Frequency Valves
- High Pressure Valves
- Direct Acting Valves
A pilot valve is a small valve that controls a limited-flow control feed to a separate piloted valve. Typically, this valve controls a high pressure or high flow feed.
Foot Pedal Valves
A Foot Pedal Valve is a small valve that controls a limited-flow control feed by Feet.
Disc Rotary Valves
A rotary valve is a type of valve in which the rotation of a passage or passages in a transverse plug regulates the flow of liquid or gas through the attached pipes.
A Hand Valve is a small valve that controls a limited-flow control feed by hands.
Speed Control Valves
Speed Control Valve is also termed as the Final Control Element. The opening or closing of Speed control valves is usually done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on Pneumatic signals.
Quick Exhaust Valves
A Valve which immediately opens its outlet to exhaust, whenever the pressure of the air decreases at the inlet.
A Non-Return valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Non-Return are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.
A shuttle valve is a type of valve which allows fluid to flow through it from one of two sources. Generally a shuttle valve is used in pneumatic systems, although sometimes it will be found in hydraulic systems.
An angle valve is a pneumatically-controlled valve with a piston actuator providing linear actuation to lift a seal off its seat. The seat is set at an angle to provide the maximum possible flow when unseated.
Hand Slide Valves
Slide valve definition, a valve that slides without lifting to open or close an aperture, as the valves of the ports in the cylinders of certain steam engines.
