The Sun Hydraulics DPBMCBN (DPBMCBN) 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 surpasses the predetermined setting. Port 4 can be blocked to prevent shifting, while port 3 serves as a work port. Direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and maintaining identical flow paths. The valve features Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or machining variations. Key specifications include a cavity size of T-21A, a series capacity of 7 gpm (28 L/min), and a maximum operating pressure of 5000 psi (350 bar). The valve accommodates control pilot flows between 7 to 10 in\u00b3/min (0.11 to 0.16 L/min) and exhibits maximum leakage of 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustment is facilitated by an internal hex screw, with settings increased by turning clockwise up to 5.5 turns. The valve has an installation torque requirement of 30-35 lbf\u00b7ft (41-47 Nm) and uses a Viton seal kit for maintenance. This product is not bistable but capable of modulating between two positions based on pressure conditions. It\u2019s crucial to monitor pilot flow consumption when pressures exceed the valve setting, as this may affect performance unless using a direct-acting version as an alternative solution. Maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints.

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.
