What is a pilot valve used for?

A pilot valve is a small valve that controls a limited-flow control feed to a separate piloted valve. Typically, this separate valve controls a high pressure or high flow feed.

What is pilot port in valve?

Pilot operated check valves work by allowing free flow from the inlet port through the outlet port. Supplying a pilot pressure to the pilot port allows flow in the opposite direction. Air pressure on top of the poppet assembly opens the seal allowing air to flow freely.

What is a pilot valve in hydraulics?

A hydraulic pilot valve is the part of the machinery that controls the high pressure of the hydraulic fluid as it passes through the machine, and regulates the functioning of the other valves. Valves in hydraulic equipment are commonly called pilot-operated valves.

What is a piloted check valve?

Pilot operated check valves (PO Check Valves) are typically used to hold pressure in a cylinder in the event of a drop in pressure or a total loss of pressure. The pneumatic check valve locks air in the device until the pilot signal is energized, at which time the valve opens and air evacuates the cylinder.

What is pilot pump?

A smaller pump in a pilot pump function is used as a supplemental pump in booster applications. Its purpose is to take over in low consumption periods and thus contribute to lower the energy consumption of the booster as a whole.

How does a 3 way pilot valve work?

This pilot valve is a small direct operated 3/2-way valve. The pilot valve delivers compressed air to a small air cylinder inside the valve. The compressed air in this cylinder pushes against the piston and actuates the solenoid to switch the valve. This way, a relatively small solenoid can be used to switch the valve.

What is a pilot operated pneumatic valve?

Air piloted valves make use of air pressure to control compressed air, liquids or gas by means of a pneumatic system. Manufacturers prefer these valves because they do not require additional electrical current or labor to operate.
