Pneumatic timer, normally closed

The time delay valve is actuated by a pneumatic signal at port 1 after a preset time delay has elapsed. It is returned to the normal position via return spring when the signal is removed. The time delay is infinitely adjustable by means of a regulating screw. The time delay is reset automatically within 200 ms.
