The Sun Hydraulics DPBCKWV (DPBCKWV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It features one blocked port and an open flow path between ports 2 and 3, making it suitable for applications where switching devices are needed. This valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 exceeds the pre-set value, with pressure at port 3 directly adding to the setting. This characteristic means that port 3 may not be usable as a work port in certain circuits; if this is a concern, a 4-port version might be more appropriate. The DPBCKWV model incorporates Sun's floating style construction to minimize binding risks due to excessive installation torque or machining variations. It is not bistable but can modulate between two positions as required by system conditions. When pilot pressure exceeds the valve setting, pilot flow becomes a consideration; performance curves provide guidance on pilot consumption versus load pressure above the valve setting. Key specifications include a cavity of T-11A, series 1, and a capacity of 7 gpm (28 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and maximum valve leakage at specific conditions is limited to 1 in\u00b3/min (15 cc/min). Adjustments can be made via an internal hex screw with specific torque requirements for installation and locknut adjustments. The model weighs approximately .60 lb (0.30 kg) and uses Viton seals for durability under various conditions.

Pilot-operated, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
- Port 3 can be blocked to prevent the valve from shifting.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
