The Sun Hydraulics DPCMLWV (DPCMLWV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds its preset setting, and port 4 can be blocked to prevent shifting. Additionally, port 3 can serve as a work port. This model exhibits interchangeability with direct-acting versions, fitting identical cavities and flow paths. The pressure at port 4 directly adds to the valve\u2019s setting, allowing modulation between two positions rather than bistable operation. Port 3's maximum pressure should not exceed 3000 psi (210 bar) due to fatigue strength limits. The valve features Sun's floating style construction to reduce internal binding from installation torque or machining variations. It fits a T-22A cavity and belongs to Series 2 with a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), and it operates under a maximum pressure of 5000 psi (350 bar). Control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), while maximum valve leakage is rated at 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments are made via an internal hex adjustment screw with specified torque settings for both the valve and locknut components. Weighing approximately .60 lb (0.30 kg), it comes equipped with Viton seal kits for enhanced durability in hydraulic systems requiring reliable switching capabilities without bistable limitations.

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.
