The Sun Hydraulics DPBACWV (DPBACWV) is a versatile, normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device capable of functioning independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve activates when the pressure differential between port 1 and port 3 surpasses its preset threshold. Notably, pressure at port 3 directly adds to the valve's setting, possibly limiting its use as a work port unless utilizing the four-port variant. The DPBACWV is not bistable but can modulate between two positions as required. It accommodates maximum pressures of up to 3000 psi (210 bar) at port 3 due to fatigue strength constraints rather than hydraulic limitations. When pilot pressure exceeds the preset level, pilot flow considerations may arise; if so, opting for a direct-acting version could mitigate this concern. The DPBACWV features Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations in cavity/cartridge interfaces. Its cavity type is T-11A with a series designation of 1 and offers a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with maximum operating pressures reaching 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage at specified conditions is limited to 1 in\u00b3/min (15 cc/min). The valve requires an installation torque of between 30 and 35 lbf ft (41 and 47 Nm) and includes an adjustment mechanism that allows for pressure setting increases via clockwise turns\u2014up to a total of five-and-a-half turns. The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for maintenance purposes.

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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- 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.
