The Z1S6T50-4X/V check valve belongs to the Z1S Check Valves series manufactured by Bosch Rexroth for hydraulic automation circuits that require reliable one-way flow control. It uses a straight-through design in valve size 6 that channels fluid only from T1 to T2, minimizing pressure loss in manifold blocks. A cracking pressure of 5 bar sets the opening point so downstream loads stay pressurized until that threshold is reached. The construction tolerates a maximum operating pressure of 350 bar, making it suitable for high-pressure clamping or punching systems. Mounting follows the ISO 4401-03-02-0-05 pattern, and the identical NFPA footprint T3.5.1 D03 allows direct interchange with CETOP 03 sub-plates. Because the unit can be installed in any position, designers have flexibility when arranging stacking valves and servicing assemblies.
The valve admits up to 40 l/min of hydraulic fluid, giving clear limits for pump sizing and avoiding excessive velocity through the seat. Acceptable viscosity spans from 2.8 mm²/s to 500 mm²/s so standard mineral oils and several synthetic blends can be used without altering response time. Operating fluid temperature may range between −20 °C and 80 °C, covering cold starts and sustained high-duty cycles. A cleanliness level of ISO 4406 20/18/15 is required to reduce wear on sealing edges and maintain consistent closure. Internal sealing elements are produced from FKM material, offering compatibility with elevated temperatures and common hydraulic media while retaining low leakage characteristics.
