1/4 & 3/8 NPTF Adjustable "Quick Stop" Pilot Operated Check Valve for Faster Stops

Patents Pending


Basic Operation:


Locks any pneumatic device in position when a pressure drop or total loss of pressure occurs. Standard pilot-operated check valves will not close fast enough when back pressure is present in the pilot line. Increasing the spring pressure causes the valve to close before all the air exhausts, resulting in faster stops.
