Hydraulic Pilot Operated - Switching Isolator Valve - Check Valve (Bosch - Rexroth) , Without Drain Connection - Type SV. - Nominal Size NS20. - Qmax. = approx. 350 L/min. - Pmax. = 315 bar. - (P)(B)- Without Pre-Opening. · 模型 51185
The Bosch Rexroth SV20PB1-4X/ is the specific pilot-operated check valve for subplate mounting that matches your configuration without pre-opening . ✅ Confirmed Technical Specifications Parameter Specification Type SV (Pilot oil return internal) Nominal Size 20 (NG20) Maximum Operating Pressure 315 bar Maximum Flow Rate 350 L/min Mounting P – Subplate mounting Pre-opening B – Without pre-opening Porting Pattern ISO 5781-08-10-0-16 Weight Approx. 4.7 kg Cracking Pressure 2.5 bar Minimum Pilot Pressure 5 bar 💡 Understanding the "B" Version (Without Pre-Opening) The key feature of this valve variant is that it lacks the two-stage decompression mechanism. In valves without pre-opening (Version B), the pressure volume may be unloaded suddenly, leading to switching shocks, premature wear, and increased noise . This version is suitable for applications where controlled decompression is not critical.
