- Double Pilot Operated Check Valves
- Typical application for this valve is load holding when pump is off
- The valve allows flow to pass form (V1) to (C1) and (V2) to (C2)
- The valve blocks flow form (C1) to (V1) and from (C2) to (V2)
- Blocked flow is released when pilot pressure is applied to port opposite valve (V1) and/or port (V2) accordingly
- The valve has a 6.7:1 pilot ratio, so at least 0.141 of the load pressure at port (C1) or (C2) is required at the pilot lines ports (V2) or (V1) respectively to open the flow passage to allow flow from ports (C1) or (C2) respectively
- The check is spring-biased at 50 PSI to assure holding in static or no-load conditions
- Hardened interal parts for long life
- Anodized aluminum body for corrosion protection
