HD – M-SR Cartridge – Check Valve
Streamline your custom manifold block designs and guarantee absolute fluid control with the HD M-SR Series. Available through THM Hydraulics, this right-angled cartridge check valve is engineered specifically for deep integration into complex hydraulic blocks. Designed to permit high-volume, unrestricted flow in one direction while providing a 100% leak-free closure in reverse, the M-SR series effortlessly manages extreme operating pressures up to 315 bar and massive flow rates up to 400 L/min. By utilizing a compact cartridge architecture and offering six customizable opening pressures, this valve empowers engineers to build highly efficient, space-saving, and leak-proof hydraulic systems.
Core Technical Specifications

Key Features & Engineering Advantages:-
- Optimized Manifold Integration: The right-angled cartridge design is built specifically to be machined directly into custom hydraulic manifold blocks. This completely eliminates the need for external piping or bulky subplates, resulting in a highly compact and clean system layout.
- Absolute Leak-Free Seating: Features a precision-ground internal poppet that ensures zero fluid bypass when the valve is in the closed position, making it perfect for load-holding and accumulator isolation.
- Highly Customizable Sensitivity: With 6 different opening (cracking) pressures available, you can perfectly calibrate the valve's resistance to match the exact sequencing, anti-cavitation, or back-pressure requirements of your specific circuit.
- Massive Flow Efficiency: Despite its compact footprint inside the manifold, the internal geometry is optimized to handle massive fluid volumes up to 400 L/min with minimal pressure drop, ensuring maximum power delivery to your actuators.
- Rugged 315 Bar Endurance: Forged from high-strength materials to comfortably withstand the continuous, high-intensity pressure cycles typical of heavy industrial and mobile machinery.
Ideal Industry Applications
The compact cartridge design and leak-free reliability make the HD M-SR Check Valve the premier choice for:
- Custom Hydraulic Manifolds: Serving as the internal flow-control building blocks for specialized, multi-function power units across all industries.
- Heavy Industrial Presses: Providing critical, leak-free load holding within the integrated control blocks of massive metal forging and stamping equipment.
- Mobile & Construction Equipment: Saving vital space and weight on excavators, cranes, and loaders where compact block design is mandatory.
- Injection Molding & Plastics: Ensuring precise pressure retention for high-speed clamping and injection circuits without adding external bulk.
Why Choose the HD M-SR Series?
- Shrink Your Machine's Footprint: By hiding the check valve inside the manifold block, you reduce the overall size and weight of your hydraulic control center.
- Eliminate External Leaks: Fewer external valves mean fewer O-rings, subplates, and steel lines that can vibrate loose and leak under high pressure.
- Dial In Your Circuit: The choice of 6 cracking pressures ensures this valve acts exactly how your hydraulic schematic dictates, preventing erratic actuator movements.
