The Sun Hydraulics DPCMCWN (DPCMCWN) is a normally open, pilot-operated, 2-way directional cartridge valve used in moderate flow circuits. This versatile component can function independently or actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the preset threshold. Port 4 can be blocked to prevent shifting, while port 3 serves as a work port with a maximum allowable pressure of 3000 psi due to fatigue strength limits. The valve's design allows for interchangeability with direct-acting versions, fitting the same cavities and maintaining identical flow paths. The DPCMCWN is capable of modulating between two positions rather than being bistable, making it suitable for applications requiring precise control. It features Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. The valve has a cavity size of T22A and belongs to series 2, with a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). For optimal performance, consider pilot flow consumption when the pilot pressure exceeds the valve setting; if this becomes an issue, switching to the direct-acting version may be beneficial. The DPCMCWN includes specific adjustment features: a screw internal hex size of 5/32 in., locknut hex size of 9/16 in., and requires an installation torque between 45-50 lbf ft (61-68 Nm). The model weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for maintenance.

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.
