Pilot to Open Check Valve
Uses of pilot-to-open Check Valves (CO):
- allows free flow from one port to another and prevent backflow
- Special note on Pilot-to-Open check vales: CO valves block reverse flow until a pilot pressure directly proportional to the load pressure is sensed at port 3 (Pilot). A pilot piston then pushes the check poppet off its seat, making them well suited for many clamp holding applications.
Specifications of Pilot-to-Open Check Valves (CO):
- Rated flow of up to 480 LPM
- Maximum pressure of 350 Bar
- Maximum leakage of 1 drop per min
- Cracking pressure of 0.3 Bar, but other cracking pressures can be offered upon request
- CO pilot ratio is 3:1, making it suitable for most applications
Special features of Pilot-to-Open Check Valves (CO):
- Extremely low leakage on closing relative to other Check valves
