Pilot Operated Check Valve
Home > Directional control valve > Pilot Operated Check Valve CPDG‧CPDT series > Pilot Operated Check ValveModel CPDT-04
Feature:- This pilot controlled check valve allows flow in one direction and prevents flow in the reverse direction unless cracking pressure is required to open the valve so then it allow the flow freely reverse. If the cracking pressure is closed, then the internal pressure in the system could be maintained.
- Two-steps design of pilot controlled check valves has been interchanged which is able to operate via lower pressure so then it reduces the noisy occurred by impulse so the quality is more advanced.
- These check valves allow free flow in one direction and prevent reverse flow in the reverse direction until operated by a pilot pressure to allow free reverse flow.
- The specified cracking pressure is required to open the valve to allow free flow direction.
