4V210-08 1/4'' 5/2 Way Air Control Single Solenoid Pneumatic Valve

Pneumatic solenoid valve takes an electrical signal (ac or dc Voltage) and opens or closes the air supply going to your pneumatic actuator. Very basic solenoids consist of an electromagnetic coil, a plunger or piston, a piston return spring, and a valve body. When you apply electrical power to the coil, it attracts the piston and causes it to move inside the valve body. This, in turn, opens or closes ports inside the valve body allowing your air supply to operate the pneumatic actuator. When the electric supply is removed, the piston spring returns the piston to its original position and shuts off the air supply to the pneumatic actuator.

Typical applications
5/2-way valves are used to actuate double acting pneumatic actuators, such as pneumatic cylinders, rodless cylinders, grippers and rotary actuators. Double acting actuators require compressed air to move in both directions. To decide whether a mono-stable or bi-stable 5/2-way valve should be applied, it is necessary to know more about the system’s design and requirements.

The number of actuators determines the required number of valves: each actuator or group of actuators needs its own control valve. The PLC limits the number of coils that can be energized. Mono-stable valves (with one solenoid coil) require less wiring and PLC outputs than bi-stable valves (with two solenoid coils). Some manifolds have internal wiring and have one connector that connects to all valves, for example a 25 pin D-SUB connector. In this specific case, only 12 bi-stable valves could be installed compared to 25 mono-stable valves.

The choice between mono-stable and bi-stable valves is often motivated by safety requirements. In some machine designs, to prevent machine damage or injuries, it might be desired that the actuator returns to the base position during power loss. In such cases a mono-stable valve is recommended. In other designs, bi-stable valves are better suited if the requirements are to keep the actuator in the last position.
