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.

Logic Systems

Logic units are best thought of as miniature valves, whose purpose is to influence the behaviour of larger power valves. They achieve this by producing and receiving output and input signals, using the common air supply. In this way, they are able to monitor and control a whole sequence of operations with great accuracy and repeatability.
