The Sun Hydraulics DPBMLAV (DPBMLAV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a pre-set value, with the option to block port 4 to prevent shifting and use port 3 as a work port. The valve's design allows for easy interchangeability with direct-acting versions, as they fit the same cavities and share identical flow paths. Notably, pressure at port 4 directly adds to the valve's setting, allowing for modulating capabilities between two positions rather than being bistable. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. If pilot flow becomes an issue when pilot pressure surpasses the valve setting, switching to a direct-acting version may resolve it. The valve incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a cavity size of T-21A, series 1 capacity of 7 gpm (28 L/min), and factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Valve leakage is minimal at a rate of up to 1 in\u00b3/min (15 cc/min) under conditions of 110 SUS (24 cSt) viscosity and a pressure of up to 1000 psi (70 bar). Additional features include an adjustment range requiring up to five clockwise turns and specific torque requirements for installation and locknut adjustments.

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.
