HD – Z2S – Check Valve Hydraulically Pilot Operated
Unlock unparalleled precision and elevate the safety of your hydraulic systems with the HD Z2S Series Hydraulically Pilot Operated Check Valve. Available through Thm Hydraulics, this highly efficient valve is designed to deliver reliable, absolute flow control for critical load-holding applications. Engineered specifically as a sandwich plate valve for vertical stacking assemblies, the Z2S series provides a 100% leak-free closure for one or two actuator ports. Capable of handling intense operating pressures up to 315 bar and massive flow capacities up to 450 L/min, this valve acts as an essential system upgrade, guaranteeing secure load retention and controlled reverse flow in demanding industrial environments.
Core Technical Specifications:-
- Component Architecture: Hydraulically Pilot Operated Sandwich Check Valve
- Model Type: HD-Z2S
- Maximum Operating Pressure: Up to 315 bar
- Maximum Flow Capacity: Up to 450 L/min
- Mounting Style: Sandwich plate for vertical stacking assemblies
- Standardization: Porting pattern to DIN 24 340 Form A, ISO 4401, and CETOP-RP 121H
Key Features & Engineering Advantages:-
- Fail-Safe Load Holding: Provides absolute, leak-free closure of one or two service ports. This ensures that hydraulic cylinders remain securely locked in position under heavy loads, preventing any drifting or sudden drops when the system is idle or during a power failure.
- Controlled Reverse Flow: Utilizing a hydraulically piloted mechanism, the valve allows the check function to be overridden by pilot pressure, enabling smooth and controlled fluid return when it is time to retract the cylinder or reverse the load.
- Space-Saving Vertical Stacking: The sandwich plate design allows the valve to be stacked directly beneath your directional control valves on the manifold block. This eliminates the need for bulky external piping, saving valuable space and reducing potential leak points.
- Universal Standard Compatibility: Strictly adheres to global DIN, ISO, and CETOP mounting patterns, ensuring this valve serves as a seamless, high-performance "drop-in" integration for standard manifold blocks worldwide.
- High-Flow Efficiency: Despite its compact vertical profile, the internal geometry is optimized to handle massive fluid volumes up to 450 L/min with minimal pressure drop, ensuring your actuators operate at peak efficiency.
Ideal Industry Applications:-
The leak-free reliability and compact stacking design make the HD Z2S Valve the premier choice for:
- Heavy Industrial Presses: Securing the massive weight of press platens in the raised position during idle times, ensuring maximum operator safety.
- Mobile & Lifting Equipment: Safely locking the boom, arm, and outrigger positions on excavators, cranes, and heavy-duty loaders.
- Injection Molding & Plastics: Maintaining precise, uniform mold-locking pressure throughout the entire high-speed injection cycle without needing continuous pump operation.
- Machine Tooling & CNC: Providing critical, space-saving circuit isolation in the compact, high-density manifolds of automated manufacturing centers.
Why Choose the HD Z2S Series?
- Upgrade Your System Safety: Protect your equipment and your workforce. When the Z2S valve closes, the load stays exactly where you put it, eliminating the dangers of internal fluid slip.
- Shrink Your System Profile: The sandwich plate design gives you advanced pilot-operated control without adding a single inch of external steel tubing to your machine.
- Global Mounting Standard: Because it fits standard DIN/ISO/CETOP patterns, upgrading your current manifold to include this safety check valve is a simple, bolt-on process.
