The SV 10 PB1-4X/ valve series from Bosch Rexroth is an isolator valve designed for leak-free blocking of one actuator port, and it meets your stated requirements. ✅ Valve Specifications The search results for your specified configuration are detailed in the table below. Parameter Specification Source(s) Model Type SV 10 PB1-4X/ (or similar) Nominal Size NS10 (also known as NG10 / CETOP 5) Maximum Operating Pressure 315 bar Maximum Flow up to 550 l/min (surpasses your 150 l/min requirement) Mounting Subplate Mounting ("P" in the type code) Pre-opening Without Pre-opening ("B" in the type code) Porting Pattern ISO 4401 and ISO 5781 standards 🔧 Understanding the Type Code The ordering code is structured to precisely define the valve. Here is how your requested specifications translate: SV: Pilot-operated check valve type. 10: Nominal size 10 (NS10). P: Designates subplate mounting. B: Indicates the version without pre-opening. 1: Denotes the standard cracking pressure (1.5 bar). Other cracking pressures are available. 4X: Component series 40 to 49 (installation dimensions remain unchanged within this series). 💡 Function of Version "B" (Without Pre-opening) As you specified without pre-opening (version "B"), the valve operates differently from its "A" counterpart. Function: When pilot pressure is applied at port X, the control spool moves and lifts the main seat poppet directly. Impact: The pressurized volume on the actuator side may be unloaded suddenly. This can lead to switching shocks and increased noise, which may cause premature wear on components. Version "B" is suitable for applications where controlled decompression is not a critical requirement. You may consider version "A" with pre-opening if your application benefits from dampened decompression to avoid switching shocks.
