Core Positioning

Core Design & Performance Advantages

1. 315bar High-Pressure Rated Stable Performance

   Adopts a high-strength forged valve body and precision-machined internal core components, with an optimized pressure regulating spring and sealing structure, supporting a 315bar rated working pressure. It can stably limit the maximum pressure of high-pressure hydraulic circuits, effectively avoid overpressure damage to hydraulic pumps, pipelines and executive components, and ensure the safe operation of the entire hydraulic system under heavy-load working conditions.

2. Pilot-Operated + Solenoid Control Dual Design

   Integrates the advantages of pilot-operated pressure regulation and electromagnetic on-off control: the pilot valve realizes precise and fine-tuned pressure setting with low operating force, and the main valve completes large-flow pressure relief to adapt to the high-flow demand of medium and large hydraulic systems; the 6EW110N9K4 AC solenoid valve realizes electric control of the relief function, enabling remote on-off control of the pressure relief circuit and seamless connection with industrial control systems (PLC/button station) for intelligent hydraulic system management.

3. Standard 6EW110N9K4 Universal Electric Control Configuration

   The 6EW110N9K4 solenoid module supports AC110V industrial power supply, with reliable electromagnetic actuation, fast response speed and strong anti-interference ability. The N9K4 sealing and structural design meets the IP protection grade of industrial hydraulic equipment, ensuring stable operation in harsh working environments such as vibration, dust and oil pollution, and reducing the failure rate of the electric control part.

4. Full Compatibility with DBW Series (DBW10/DBW20/DBW30)

   As the core large-size model of the DBW30 series, it shares the same industrial hydraulic matching parameters, installation interface standards and control logic with the DBW10 (small-size) and DBW20 (medium-size) series. It supports seamless drop-in replacement and flexible assembly, and can be perfectly matched with other DBW series relief valves to form a complete pressure protection system covering small, medium and large flow hydraulic circuits, meeting the diversified pressure relief needs of different specifications of industrial hydraulic systems.

5. Fast Pressure Relief & Low Pressure Fluctuation

   Optimized main valve spool and flow channel structure, with large through-flow area, realizing fast pressure relief when the hydraulic system exceeds the preset pressure, effectively suppressing pressure shock and ensuring the stability of the hydraulic system; the precision-machined valve core and valve sleeve matching, with excellent sealing performance, effectively reduce internal leakage and pressure loss, and the pressure regulation deviation is small, maintaining the stable working pressure of the hydraulic circuit.

6. Industrial-Grade Durability & Easy Maintenance

   The one-piece valve body has excellent fatigue resistance and corrosion resistance, adapting to long-term continuous operation of high-pressure, heavy-load industrial hydraulic equipment; the modular design of the solenoid valve, pressure regulating knob and other components enables quick disassembly, inspection and replacement without professional debugging tools, and the pressure setting is simple and intuitive, greatly reducing the maintenance time and cost of the equipment.
