THM – Z2S6, 10, 16, 22 – Check valves
Eliminate cylinder drift and secure your heaviest suspended loads with the THM Z2S Series Pilot Operated Check Valve. Designed specifically for the extreme demands of civil and road machinery, this vertical stacking sandwich valve guarantees leakage-free closure for one or two actuator ports. Capable of handling maximum operating pressures up to 315 bar and high-volume flow rates up to 300 L/min, the Z2S Series provides the uncompromising load-holding security required for complex fluid power systems.
Key Specifications
- Valve Type: Pilot Operated Check Valve (Sandwich Plate Design)
- Available Sizes: NG6, NG10, NG16, NG22
- Maximum Pressure: Up to 315 bar
- Maximum Flow Rate: Up to 300 L/min (Sizes 16 & 22)
- Mounting Standard: Conforms strictly to DIN 24 340 porting patterns
Engineering Advantages & Features:-
- Zero-Leakage Load Holding: Precision-engineered poppets provide an absolute, drop-tight seal. This locks hydraulic fluid perfectly in place, entirely preventing boom or bucket drift when the directional valve is in neutral.
- Space-Saving Vertical Stacking: The specialized sandwich plate design allows for seamless vertical assembly directly beneath directional control valves, drastically reducing manifold size and eliminating leak-prone external piping.
- Customizable Cracking Pressures: Available with 4 optional cracking pressure settings, giving engineers the flexibility to perfectly tune the valve's opening resistance to the exact pilot requirements of the circuit.
- Universal Standard Integration: Machined to exact DIN 24 340 standards, ensuring rapid, drop-in installation across standardized heavy-duty hydraulic blocks.
Primary Industry Applications:-
Engineered for the relentless conditions of the job site, the Z2S Series is the premier safety and control choice for:
- Heavy Civil & Road Machinery: Securing the massive lifting cylinders, leveling screeds, and steering mechanisms on large-scale asphalt pavers, motor graders, and road rollers.
- Earthmoving Equipment: Providing fail-safe load suspension for the main boom and stick cylinders on heavy tracked excavators and high-capacity trenching equipment.
