The Sun Hydraulics DPCBKHV (DPCBKHV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be utilized to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold. Notably, pressure at port 3 directly adds to the valve's setting, which may limit its use as a work port in certain circuits; if necessary, a 4-port version might be more suitable. The DPCBKHV is interchangeable with direct-acting versions, sharing cavity fit and flow paths, but it is not bistable and can modulate between two positions. The valve features Sun's floating style construction to prevent internal part binding due to excessive installation torque or machining variations. It has a capacity of 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with maximum valve leakage at 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). Adjustments are made via an internal hex screw with up to five clockwise turns increasing the setting. Installation requires specific torque settings: valve installation torque is between 45-50 lbf ft (61-68 Nm), and locknut torque ranges from 80-90 lbf in (9-10 Nm). The model weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for cartridge sealing. This pilot-operated valve is particularly beneficial when modulating flow is required without bistability concerns, making it ideal for applications needing precise control over hydraulic circuits within its specified operational limits.

Normally closed, 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.
