The solenoid valve used for our pneumatic actuators is a 4-way, on/off, electrically controlled valve. An electrical signal to the solenoid's coil switches the compressed air supply to the actuator cavities, as follows: The solenoid valve is used with the actuator, and simultaneously pressurizes Port A while exhausting the end cap cavities through Port B, or vice versa. The solenoids are furnished with mufflers and speed controls. The muffler reduces the sound of the exhausting air, and the speed control determines the cycle time of the actuator. | |
