Push Pull Valves are used to operate Pneumatic Cylinders. In the absence of electrical supply, manually operated valves such as Push Pull Valves are used. The functioning is the same; however, the solenoid coil is replaced by a knob, which controls the movement of the spool inside the valve, thereby allowing the air to pass.
Solenoid Two way valves
(0 Customer reviews)Each of the two ports on a two-way valve is alternately used to permit flow as well as close it off. A two-way valve can be specified to be either “normally open” or “normally closed” in its operation. With a normally open valve, the valve remains open until some type of current is applied to close the valve. Suspension of the electrical power causes the valve to automatically reopen to its normal state. A normally closed solenoid valve is the most common, working in the opposite fashion, remaining closed until a power source causes it to open

Regulators
( Customer review)
Each pneumatic system has an optimal operating pressure and exceeding this pressure results in excessive wear and wastes compressed air. Regulators are designed to maintain a consistent prescribed outlet pressure regardless of the inlet pressure and also maintain a consistent pressure regardless of flow rate requirements. The precision needed to maintain the regulation and flow requirements determines the type and cost of regulators needed.
Solenoid Pilot operated valves
( Customer review)
In pilot operated valves, the plunger opens up the pilot opening while built-up pressure causes the valve to open and close.
Although piloted valves require less electrical energy to operate, they usually need to maintain full power in order to remain in an open state, and they perform at a slower rate than direct acting solenoids. Direct acting solenoid valves only need full power when opening the valve, as they can hold their open position even when operating on low power.
