Hydraulic Directional Control Topics Check Valves Shuttle Valves Two-way WebDescription. Series VR1210/1200 shuttle valve is a 3 ported valve with one output and 2 pneumatic signal and input ports. Output is always supplied by high pressure inlet. The VR12**F series are interrupters for control of air pressure signal system lines. Piping is possible in any position and the one-touch fittings make piping connections simple.

WebA common reason is that you could still have pressure on the opposing port. Again, a shuttle valve is not a selector—it is looking for one signal at a time, not two. Check to see if you have pressure in the opposing port that is somehow getting trapped in the system’s pneumatic circuit. Using the proper valve and sending the signal could be ... Web1216. Prefill valve ( PV 100 - 200 ) - 21 Series. The Prefill Exhaust Valve (PV) is a hydraulic-pilot operated check valve with seat type construction. It allows free flow from port A to port B. Flow from port B to port A can be enabled by applying pilot pressure to it's port X. The decompression feature enables the valve to open in two stages ... WebJan 23, 2024 · Swing Check Valve.
