Pneumatic timer (time delay valve). In the normal position, port 1 is switched through to port 2. The pneumatic timer is started by a pneumatic signal at the control port. It is actuated at the end of a set time delay and reset via spring return to the initial position after the signal has been removed. The time delay is infinitely adjustable between 2 and 30 sec. via an adjusting knob.
