PILOT OPERATED CHECK VALVES. They are non-modulating valves which allow free flow through the check valve into the actuator (V2 to C2) and then block the reverse flow until they feel a pilot pressure directly proportional to the load in the pilot line, so that the pilot piston can push the check poppet off its seat.

The isolator valve type Z2S is a releasable check valve in sandwich plate design. It is used for the leakage-free blocking of one or two actuator ports, also in case of longer standstill times. In direction A① to A② or B① to B②, there is a free flow; in the opposite direction, the flow is blocked.
flow is possible only when sufficient pilot pressure is applied at V2 or V1, which act as cross connected pilot ports, and the pilot piston lifts the poppet from its seat overcoming cylinder port pressure. In case of valve application in redundancy systems it is especially recommended to use version with sealed pilot piston.
Pilot operated check, single. VSO-SE. RE 18307-01. Edition: 09.2019 Replaces: 11.2018. 05.52.79 - X - Y - Z. Description. Flow is allowed to pass from V2 to C2 when pressure at V2 rises above the spring bias pressure and the poppet is pushed from its seat.
Check valve | SV; SL 5/18 RE 21468, edition: 2018-06, Bosch Rexroth AG Function, section The isolator valve type SV/SL is a pilot operated check valve for subplate mounting or threaded connection. It is used for the leakage-free blocking of one actuator port, also in case of longer standstill times. The valve basically consists of a housing (1 ...
The isolator valve type Z2S is a releasable check valve in sandwich plate design. It is used for the leakage-free blocking of one or two actuator ports, even for long standstill times. In direction A1 to A2 or B1 to B2, there is a free flow; in the opposite direction, the flow is blocked.
