3/8 NPTF Pilot-Operated Locking Valves with Flow Control

Patents Pending

Basic Operation:

Lock your pneumatic device in position when a pressure drop or total loss of pres- sure occurs. Slowly lower the load when the valve is piloted open. The manual release for exhausting trapped air is also metered through the flow control, so the load is lowered slowly when the manual release is depressed.
