HD – Z1S – Check Valve
Streamline your manifold design and ensure absolute fluid control with the HD Z1S Series Check Valve. Supplied by THM Hydraulics, this highly efficient valve is specifically engineered as a sandwich plate component for use in vertical stacking assemblies. Designed to permit unrestricted flow in one direction while providing a 100% leak-free closure in reverse, the Z1S series effortlessly manages operating pressures up to 315 bar and flow rates up to 100 L/min. By integrating directly into your vertical stacks, this valve eliminates the need for bulky external piping, offering a compact, leak-proof solution for complex industrial and mobile hydraulic circuits.
Core Technical Specifications:-
- Component Architecture: Sandwich Plate Check Valve (Non-Return Valve)
- Model Type: HD-Z1S
- Maximum Operating Pressure: Up to 315 bar
- Maximum Flow Capacity: Up to 100 L/min
- Mounting Style: Vertical Stacking Assembly
- Configurations: 8 distinct isolating functions available
Key Features & Engineering Advantages:-
- Space-Saving Sandwich Design: Engineered to be stacked directly under directional control valves on a standard manifold block. This vertical integration drastically reduces the footprint of your hydraulic circuit and minimizes potential external leak points.
- 8 Versatile Isolating Functions: Highly customizable to fit your exact schematic. With 8 different internal configurations, you can choose to isolate the flow in the A, B, P, or T lines, giving your engineering team total control over circuit protection.
- Absolute Leak-Free Closure: Features a precision-ground poppet and seat mechanism that ensures zero fluid bypass when the valve is closed, perfectly maintaining pressure for load-holding or accumulator circuits.
- Optimized Flow Dynamics: Despite its compact vertical profile, the internal galleries are designed to handle up to 100 L/min with minimal pressure drop, ensuring your actuators receive the full power of the hydraulic fluid.
- Rugged 315 Bar Endurance: Forged from high-strength materials to withstand the continuous, high-intensity pressure cycles typical of heavy industrial machinery.
Ideal Industry Applications:-
The compact stacking design and leak-free reliability make the HD Z1S Check Valve the premier choice for:
- Machine Tooling & CNC: Providing critical circuit isolation in the compact, high-density manifolds of automated lathes and milling centers.
- Compact Hydraulic Power Units (HPUs): Saving vital space in small-scale power packs used for material handling and mobile equipment.
- Industrial Automation: Protecting sensitive directional valves from load-induced back-pressure in robotic assembly lines and conveyor systems.
- Plastics & Rubber Manufacturing: Ensuring precise pressure retention for auxiliary clamping and ejector functions on injection molding machinery.
Why Choose the HD Z1S Series?
- Shrink Your System Footprint: By stacking the check valve vertically, you free up valuable horizontal space on your manifold block, allowing for smaller, lighter machine designs.
- Tailored Circuit Protection: With 8 different isolating functions, you aren't forced into a "one-size-fits-all" solution. You can block reverse flow exactly where your circuit demands it.
- Zero Plumbing Headaches: Sandwich plates eliminate the need for cutting, threading, and installing external steel lines, dramatically speeding up your machine assembly time.
