The Sun Hydraulics DPBMKWV (DPBMKWV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile in application, capable of operating independently or as an actuator for larger pilot-operated directional or logic cartridges. The valve shifts based on the pressure differential between port 1 and port 4, with the option to block port 4 to maintain its position. Port 3 can function as a work port, and the valve's design allows for interchangeability with direct-acting versions due to identical cavity fittings and flow paths. The DPBMKWV incorporates Sun's floating style construction, minimizing internal binding risks from installation torque or machining variations. It offers a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The valve is not bistable but can modulate between two positions. It features a maximum leakage rate of 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar) and requires an installation torque of 30-35 lbf\u00b7ft (41-47 Nm). The adjustment mechanism includes an internal hex screw with a locknut requiring a torque of 80-90 lbf\u00b7in (9-10 Nm). This cartridge valve is suitable for applications where precise control over switching devices in hydraulic circuits is needed. Its robust design, combined with adjustable settings and low leakage rates, makes it ideal for maintaining system stability under varying pressures. Additionally, the use of high-quality Viton seals ensures durability and reliability in demanding environments.

Normally open, pilot-operated, 2-way directional cartridges are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the setting.
- Port 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- When pilot pressure exceeds the valve setting, pilot flow may be a consideration. See performance curves for pilot consumption vs. load pressure above the valve setting. If this is a problem, the direct acting version of this valve would be a solution.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
