Hydraulic Pilot Operated - Switching Isolator Valve - Check Valve (Bosch - Rexroth) , Without Drain Connection - Type SV. - Nominal Size NS30. - Qmax. = approx. 550 L/min. - Pmax. = 315 bar. - (G)(A)- With Pre-Opening. · 模型 51179
The Bosch Rexroth SV 30 G A 1-4X/ valve matches your specifications: a pilot-operated check valve with a nominal size of NS30, threaded connection (G), and the version with pre-opening (A). The maximum flow for this valve size is up to 550 l/min, which exceeds your specified 350 l/min requirement . ✅ Valve Specifications and Ordering Code Your specifications translate directly into the Rexroth ordering code, which is structured as follows : Parameter Code Meaning Type SV Pilot-operated check valve with internal pilot oil return (no drain connection) Size 30 Nominal size 30 (NS30/NG32) Connection G Threaded connection according to ISO 228-1 Pre-opening A Version with pre-opening for dampened decompression Cracking Pressure 1, 2, 3, or 4 Code 1 (2.5 bar standard) to 4 (10 bar max) Component Series 4X Component series 40 to 49 (dimensions remain unchanged) A complete ordering code for your configuration follows this pattern: SV 30 G A 1-4X/... . 📊 Key Technical Specifications (NS30 / NG32) The technical data confirms the following details for this configuration : Parameter Specification Maximum Operating Pressure 315 bar Maximum Flow Up to 550 l/min (your specified 350 l/min is well within capacity) Minimum Pilot Pressure 5 bar Cracking Pressure (Code 1) 2.5 bar (other options: 5, 7.5, 10 bar) Weight Approx. 10 kg Pilot Volume (Port X) 19.27 cm³ 💡 Understanding the "A" Version (With Pre-Opening) The version with pre-opening offers distinct operational benefits : Operation: When pilot pressure is applied at port X, the control spool moves and first lifts a small ball poppet (pre-opening), followed by the main seat poppet. Benefits: This two-stage setup provides dampened decompression of the pressure volume on the actuator side, effectively avoiding switching shocks and reducing noise. It also ensures secure unloading even with low pilot pressure, preventing premature wear on system components .
