Pilot Check Module CETOP03 / NG6 Description The Z2DS series pilot operated check valve module are designed to give leak free closing of one or both service ports (A & B). When hydraulic oil flows from A(in) to A(out) the pilot operated check valve is freely opened, at the same time pressure is applied via a pilot spool to shift the check valve in B line to allow oil to flow from B(out) to B(in). When pressures are reduced the pilot spool is centred and both A and B check valves lock.
