Due to seven years of experience in cooperating with Rexroth from 1979, Huade has incorporated cutting-edge technology from Rexroth. Huade® check valve Z2S 6 can completely replace the same series offered by Rexroth. It has a better price. The factory has passed ISO9001, ISO14001, and OH SAS18001. Huade® hydraulic valves are used in the military industry due to reliable performance. It is more advanced in technology and more durable than the similar products in this line. It is a well-know national brand in China.

Features:
▶ For use in vertical stacking assemblies
▶ For the leak free closure of one or two service ports
▶ Porting pattern to Din 24 340 form A, ISO4401 and CETOP - RP 121H
Application:
This check Valve Z2S is used for vertical stacking installation. It can seal one or two working oil ports without leakage as needed.
Hydraulic pilot operated check valves type Z2S are of sandwich plate design. They are used for the leak-free closure of one or two service ports, even for long periods of time. Free flow occurs from A1 to A2 or B1 to B2. Flow in A1 B1 the opposite direction is blocked. When fluid flows from A1 to A2, the spool (1) is pressured and is pushed to the right, thereby opening the ball poppet valve (2) which then opens the poppet(3). In order to ensure correct closing of the valve, the A2 B2 service ports of the directional valve must be connected to tank in the neutral position.
