The Sun Hydraulics DPCBKEV (DPCBKEV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 surpasses a specific setting, with pressure at port 3 directly adding to this setting. As such, port 3 might not be suitable as a work port in certain circuit designs, but a four-port version of this valve could address this issue. The DPCBKEV offers interchangeability with direct-acting valves, sharing the same cavities and flow paths. However, it is not bistable and can modulate between two positions. The maximum pressure at port 3 is recommended to be limited to 3000 psi (210 bar) due to fatigue strength considerations rather than hydraulic limits. When pilot pressure exceeds the set threshold, pilot flow becomes a factor; if excessive consumption occurs, switching to a direct-acting version may be beneficial. This valve incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. Key specifications include a T2A cavity, Series 2 classification, and a capacity of 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), while maximum leakage at standard conditions is limited to 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). The valve features adjustable settings with up to five clockwise turns for increased settings and requires specific torque values for installation and locknut adjustments.

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.
