The SV10GB1-4X/ valve belongs to the Hy-Check Valves series from Bosch Rexroth and is installed in hydraulic systems to block reverse flow until a pilot signal opens the passage. It has a nominal size of 10 for compatibility with mid-range circuit manifolds. The connection is a threaded G port that follows ISO 228-1 threads, so standard fittings can be used without adapters. Flow is free from port A to port B, and reverse flow is held closed until pilot pressure is applied. The built-in spring sets a cracking pressure of 1.5 bar, allowing low resistance when the valve opens. The unit can be mounted in any position, which simplifies layout inside machinery. When supplied with the threaded body, the valve weighs 2.1 kg. The hydraulic fluid feeding the valve must meet ISO 4406 class 20/18/15 cleanliness to maintain internal sealing surfaces.
The pilot stage uses a control area of 3.8 cm² to generate force for valve actuation, and the pilot volume at port X is 2.5 cm³, which defines the volume that must be pressurized during switching. Continuous service is rated for operating pressures up to 350 bar, and the same 350 bar limit applies to the pilot port, so full system pressure can be used to open the valve. Valve release begins when pilot pressure reaches 5 bar. The design permits fluid temperatures up to 80 °C, allowing use with standard mineral oils. Pilot oil returns internally, eliminating the need for an external drain line. The mean time to dangerous failure is 150 years, indicating a long functional safety lifespan.
