Hydraulic Pilot Operated - Switching Isolator Valve - Check Valve (Bosch - Rexroth) , Without Drain Connection - Type SV. - Nominal Size NS25. - Qmax. = approx. 550 L/min. - Pmax. = 315 bar. - (B)- Without Pre-Opening. · 模型 51181
The Bosch Rexroth SV 25 P B 1-4X/ valve matches the specifications you provided: a pilot-operated check valve, nominal size 25 (NS25), subplate mounting (P), and the version without pre-opening (B). ✅ Valve Specifications The technical data confirms the following details for this configuration : Parameter Specification Type SV (Pilot-operated check valve with internal pilot oil return) Nominal Size 25 (NS25) Maximum Operating Pressure 315 bar Maximum Flow Up to 550 l/min (your specified 350 l/min is within capacity) Mounting P – Subplate mounting Pre-opening B – Without pre-opening Porting Pattern ISO 5781 Cracking Pressure 2.5 bar (standard for code 1) 🔧 Ordering Code Breakdown Your specifications translate into the following ordering code, which follows the structure documented in the technical data sheet : SV: Pilot-operated check valve with internal pilot oil return. 25: Nominal size 25. P: Subplate mounting. B: Version without pre-opening. 1: Standard cracking pressure (2.5 bar; other cracking pressures are available with code 2, 3, or 4). 4X: Component series 40 to 49. /*: Placeholder for additional options like seal material. 💡 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 pressurized 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 a critical requirement.
