HYDC10-40 (Dual Pilot Operated Check Valve)
Description:
A cartridge-style dual pilot-operated check valve.
A cartridge-style dual pilot-operated check valve.
Operation:
The valve will block flow from ① to ②, and from ④ to ③. Flow is allowed in the opposite direction when pressure is applied to port ② and/or ③. The valve has a 3:1 pilot ratio, so at least 1/3 of the load pressure at port ① or ④ is required at the pilot lines (port ③ or ②) to open the flow passage to allow flow from port ① or ④.
