Parker Hannifin Air pressure timer PRT series

All logic units must be mounted on an individual 2 or 3 port base, sold separately. Logic units have input (green) and output (red) pressure indicators to show the state of the appropriate signals. Units come with captive screws for mounting to any type of base, and a sealing O-ring is located on the bottom of each unit.

The diaphragm moves to the top chamber, expelling air through the timing disc. The delay can be adjusted by adjusting the needle valve. High Reliability Long Life
