The Sun Hydraulics DPBMLWV (DPBMLWV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can be used independently or to activate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses a predefined setting. Port 4 can be blocked to prevent shifting, while port 3 functions as a work port. The valve is interchangeable with direct-acting versions, sharing the same cavities and flow paths. It is not bistable but capable of modulating between two positions, with pressure at port 4 directly affecting the valve setting. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. If pilot pressure exceeds the valve setting, pilot flow considerations may arise; in such cases, a direct-acting version could be preferable. The valve incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. Key specifications include a T21A cavity type, series 1 classification, and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum leakage at specified conditions being 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). Adjustment involves up to five clockwise turns to increase settings, with specific hex sizes for the valve and adjustment screw provided for precise installation and maintenance. The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for optimal performance.

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.
