THM – DB…K-Pilot Operated – Pressure Valve
Protect your complex hydraulic manifolds and ensure absolute pressure stability with the THM DB…K Series Pilot Operated Pressure Valve. Engineered as a highly compact, drop-in cartridge solution, this advanced pressure relief valve is designed to seamlessly integrate directly into custom hydraulic blocks. Capable of smoothly processing substantial flow rates up to 250 L/min while sustaining relentless maximum operating pressures up to 315 bar, the DB…K Series delivers the uncompromising over-pressure protection required by extreme heavy-duty fluid power systems. With four distinct pressure ranges and versatile adjustment options, it provides the precise, tailored system security necessary for the demanding civil, road, and earthmoving machinery that powers modern construction.
Core Technical Specifications:-
- Valve Architecture: Pilot Operated Pressure Relief Valve
- Model Series: THM DB…K
- Maximum Operating Pressure: Up to 315 bar
- Maximum Flow Rate: Up to 250 L/min
- Pressure Ranges: 50 bar, 100 bar, 200 bar, 315 bar
- Mounting Configuration: Cartridge Connection (Slip-in logic/cavity mounting)
Key Features & Engineering Advantages:-
- Space-Saving Cartridge Design: The specialized cartridge connection allows the valve to be inserted directly into a machined cavity within a hydraulic manifold. This entirely eliminates the need for bulky external subplates or leak-prone plumbing, drastically reducing the physical footprint and weight of your power unit.
- 4 Scalable Pressure Ranges: Available in 50, 100, 200, and 315 bar configurations. This allows system designers to perfectly match the valve's sensitivity to the exact safe-operating limits of the specific hydraulic circuit, preventing premature fluid dumping or dangerous over-pressurization.
- 4 Precision Adjustment Elements: Engineered with four optional pressure adjustment mechanisms. This gives technicians and engineers the flexibility to choose the exact tuning method—whether it requires secure, tamper-resistant factory settings or rapid, tactile adjustments in the field.
- High-Volume 250 L/min Capacity: The internal pilot and main poppet geometries are hydro-dynamically optimized to smoothly bleed off up to 250 liters of fluid per minute, ensuring immediate, bottleneck-free relief during sudden mechanical shock loads.
- Heavy-Duty Reliability: Machined from high-strength materials specifically selected to absorb continuous hydraulic hammering and the aggressive vibrations inherent in continuous outdoor mobile environments.
Ideal Industry Applications:-
The compact cartridge integration and robust 315-bar fail-safe protection of the DB…K Series make it an essential structural component for:
- Heavy Civil & Road Construction Machinery: Serving as the primary pressure relief element in the integrated manifold blocks of large-scale asphalt pavers, concrete slipform pavers, heavy motor graders, and road milling machines.
- Extreme Earthmoving Equipment: Safeguarding the massive boom, stick, and bucket cylinder circuits on high-capacity tracked excavators, trenchers, and wheel loaders from severe physical shock overloads.
- Heavy-Duty Material Handling: Providing critical, space-saving over-pressure protection for the heavy lifting winches and telescopic boom extensions on mobile industrial cranes.
- Compact Industrial Power Units: Managing system pressure in the dense, centralized hydraulic blocks of metal-forming presses and heavy automated manufacturing equipment.
Why Choose the THM DB…K Series?
- Manifold Optimization: The direct cartridge connection builds incredibly dense, leak-free custom hydraulic blocks.
- Uncompromising Safety: Instantly bleeds off dangerous pressure spikes to protect your entire hydraulic infrastructure.
- Tailored Performance: Multiple adjustment elements and four specific pressure ranges guarantee a perfect match for your circuit's dynamics.
