HD – DBW – Pilot Operated Pressure Relief Valve
Bring intelligent, automated pressure control to your heavy-duty circuits with the HD DBW Series Pilot Operated Pressure Relief Valve. Sourced as one of the top-quality premium hydraulic products available in India, this valve combines massive flow capacity with the precision of electronic automation. By integrating a built-on directional spool valve, the DBW series allows your system to instantly unload pump pressure to the tank via solenoid actuation, saving massive amounts of energy during idle cycles. Engineered to seamlessly manage flow rates up to 650 L/min and operating pressures reaching 350 bar, this highly adaptable valve offers the ultimate blend of mechanical safety and digital control for the nation's most demanding industrial applications.
Core Technical Specifications:-
- Component Architecture: Pilot Operated Pressure Relief Valve with Electrical Unloading
- Model Type: HD-DBW….50/….
- Maximum Operating Pressure: Up to 350 bar
- Maximum Flow Capacity: Up to 650 L/min
- Actuation/Control: Solenoid operated unloading via built-on directional spool valve
- Pressure Ranges: 50, 100, 200, 315, and 350 bar configurations
- Pressure Adjustment: 3 distinct optional adjustment elements
- Mounting Styles: Sub-plate mounting, Threaded connection, and Manifold mounting
Key Features & Engineering Advantages:-
- Instant Solenoid Unloading: The integrated directional spool valve acts as an electrical bypass. When triggered by your PLC or an operator switch, it instantly unloads the main system pressure directly to the tank at near-zero pressure. This is essential for emergency stops, safe machine start-ups, and reducing heat generation during idle phases.
- Monumental Flow Venting: The pilot-operated internal stage ensures that even when dumping up to 650 liters of fluid per minute, the valve opens and closes smoothly, eliminating violent hydraulic shock that can destroy pumps and steel piping.
- 5 Highly Tuned Pressure Ranges: Choose the exact pressure threshold your system requires—from a sensitive 50 bar up to a crushing 350 bar limit—ensuring the valve is perfectly calibrated to your specific circuit.
- Ultimate Mounting Versatility: Seamlessly integrate the valve into any setup. Choose Sub-plate mounting for clean, standardized layouts, Threaded connection for rapid in-line installations, or Manifold mounting to sink the cartridge directly into a custom control block.
- 3 Custom Adjustment Elements: Tailor the valve’s mechanical tuning mechanism to your operational environment, ensuring the maximum pressure setting remains secure against heavy machine vibration and unauthorized adjustments.
Ideal Industry Applications:-
The electrical unloading capability and massive 650 L/min capacity make the HD DBW Series the premier choice for:
- Large-Scale Hydraulic Power Units (HPUs): Serving as the master pressure relief and energy-saving unloading valve for central power packs driving entire factory floors.
- Heavy-Duty Forging & Pressing: Safely managing the intense pressure build-up during metal stamping, and allowing the main pump to idle efficiently between press cycles.
- Injection Molding & Plastics: Precisely controlling holding pressures and instantly dumping system pressure during the mold-opening and part-ejection phases.
- Primary Material Processing: Managing the extreme hydraulic forces required in steel rolling mills, large-scale mining crushers, and heavy scrap balers across India.
Why Choose the HD DBW Series?
- Slash Your Energy Costs: By automatically unloading the pump when pressure is met or the machine is idle, you eliminate wasted energy, reduce fluid temperatures, and extend the lifespan of your entire hydraulic ecosystem.
- Bridge the Gap to Automation: The built-in solenoid gives your digital control systems direct command over mechanical fluid power, allowing for highly synchronized, automated machine cycles.
- Total Integration Flexibility: Whether you are building a custom block from scratch or retrofitting an old hard-piped machine, the three mounting styles guarantee a perfect, leak-free fit.
