THM – DAW Pilot Operated Shut-off – Pressure valves
Optimize your hydraulic systems and strictly manage your pump efficiency with the THM DAW Series Pilot Operated Shut-Off Pressure Valve. Engineered for precision and reliable operation, this heavy-duty valve is designed to automatically unload the main pump to the tank when the set system pressure is reached, perfectly managing accumulator charging circuits or high-low pump systems. Capable of effortlessly processing maximum flow rates up to 240 L/min and sustaining extreme operating pressures up to 315 bar, the DAW Series ensures your power unit doesn't waste energy pushing fluid against a closed system. Equipped with a built-on directional valve for instant solenoid-actuated unloading, it is the ultimate automated pressure control solution for the heavy machinery that drives modern infrastructure and manufacturing.
Core Technical Specifications:-
- Valve Architecture: Pilot Operated Shut-Off / Unloading Pressure Valve
- Model Series: THM DAW
- Maximum Operating Pressure: Up to 315 bar
- Maximum Flow Rate: Up to 240 L/min
- Mounting Configuration: Subplate Mounting
Key Features & Engineering Advantages:-
- Solenoid Actuated Unloading: Features a specialized, built-on directional control valve that allows operators or automated PLC systems to instantly unload the pump via an electrical signal. This drastically reduces energy consumption, heat generation, and mechanical wear on the pump during idle machine cycles.
- Customizable Pressure Ratings: Engineered with 4 optional pressure ratings, allowing system designers to finely tune the valve to the exact shut-off and restart thresholds required by the specific hydraulic circuit.
- Space-Saving Subplate Mounting: Designed exclusively for subplate mounting, providing the absolute tightest, most leak-resistant mechanical seal possible while keeping your custom manifold blocks compact and organized.
- Heavy-Duty 315-Bar Resilience: Machined from premium materials to safely absorb the continuous hydraulic hammering and extreme pressure spikes inherent in heavy-duty 315-bar applications.
Ideal Industry Applications:-
The rapid solenoid unloading, massive 240 L/min flow capacity, and robust pressure regulation of the DAW Series make it an essential structural component for:
- Accumulator Charging Circuits: Serving as the primary pump unloading valve in the heavy-duty accumulator circuits of large-scale asphalt pavers, motor graders, and road milling machines.
- Industrial Hydraulic Power Units (HPUs): Providing automated, energy-saving pump unloading in the centralized power units of massive metal-forming presses, deep drawing presses, and plastic injection molding equipment.
- Heavy Earthmoving Equipment: Regulating high-low pump systems on massive tracked excavators and high-capacity wheel loaders, ensuring maximum digging power when needed and maximum efficiency during transit.
- Mobile Material Handling: Managing the complex hydraulic demands of multi-actuator industrial cranes and heavy-tonnage forklifts.
Why Choose the THM DAW Series?
- Peak Energy Efficiency: Automated solenoid unloading ensures your pump only works when it has to, drastically reducing fuel or electricity costs.
- Uncompromising Precision: Four specialized adjustment methods guarantee exact pressure scaling for your specific application.
- Manifold Optimization: The secure subplate design saves critical space in crowded engine bays and industrial power units.
