Based on the Bosch Rexroth technical documentation, a pilot-operated check valve meeting your specifications (NS10, subplate mounting, with pre-opening) is the SV 10 PA1-4X/... series. The "A" in the type code indicates the version with pre-opening for dampened decompression . ✅ Valve Specifications The SV10 PA1-4X/... valve meets your core requirements, as confirmed by the manufacturer's data sheet . Model Type: SV 10 PA1-4X/... (Pilot-operated check valve, NS10, subplate mounting, with pre-opening) Nominal Size: NS10 Maximum Operating Pressure: 315 bar Maximum Flow: 550 L/min (The valve's max flow exceeds your 150 L/min spec) Mounting: Subplate mounting ("P" in the type code) Pre-opening: Yes ("A" in the type code) 🔧 Understanding the Type Code The ordering code for this valve is structured as follows : SV 10 PA1-4X/ SV = Pilot-operated check valve with internal pilot oil return (without drain connection) 10 = Nominal size 10 (NS10) P = Subplate mounting A = Version with pre-opening (provides dampened decompression) 1 = Cracking pressure (1.5 bar standard; other pressures available) 4X = Component series 40 to 49 (unchanged installation dimensions) 💡 Function of Version "A" (With Pre-opening) The "A" version includes a two-stage opening mechanism that reduces switching shocks : When pilot pressure is applied to port X, the control spool first lifts a small ball poppet. This initial opening dampens the pressure surge in the actuator line. The main poppet then opens to allow full flow in the reverse direction. This prevents sudden, noisy decompression and reduces stress on system components .
