Product Description
Rexroth SV Series Pilot-Operated Check Valves
Product Overview: The Rexroth SV series is a high-performance pilot-operated check valve designed for the reliable locking of actuators in hydraulic systems. It allows free flow in one direction and provides a perfect poppet-style seal for zero-leakage in the reverse direction. By applying a pilot pressure signal, the internal spring force can be overcome to allow reverse flow. Its robust subplate mounting design complies with ISO 5781 standards, making it widely used in injection molding machines, hydraulic supports, and various pressure-holding circuits.
Featured models: SV10, SV15, SV20, Part Numbers R900520859, R900502808 (SV15GB3-4X), SV20GB3-4X, and SV10PA1-30.
Key Technical Advantages:
Zero-Leakage Pressure Holding: Features a hardened steel poppet and seat design to ensure absolute sealing in the closed position.
High Pressure Capability: Designed for operating pressures up to 31.5 MPa (315 bar), suitable for heavy-duty industrial cycles.
Variable Opening Ratios: Offers various pilot piston area ratios to facilitate easy decompression and opening based on system requirements.
Integrated Decompression: Select models feature a pre-opening (decompression) function to effectively eliminate hydraulic shock and vibration during initial opening.
Standardized Mounting: Compliant with international interface standards, allowing direct replacement of existing SV10PA or SV15GB valves.
