Parker PRT series 0.1s to 3s Pneumatic Timer, 8 bar max

Timer Module

A pneumatic timer consists of a solenoid coil/core, operating spring, timing disk, filter and diaphragm. The core moves up into the coil when it has been energized and this leads to pressure on the diaphragm. The diaphragm moves into the top chamber which un-traps the air through the timing disk. By altering the needle valve you can adjust the amount of delay.
