The Sun Hydraulics DPCDLDV (DPCDLDV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits, allowing fluid to flow from port 1 to port 2 while blocking port 3. This valve is versatile and can be used independently or to actuate larger pilot-operated or logic cartridges. It operates by shifting when the pressure differential between ports 1 and 3 exceeds a preset level, with pressure at port 3 directly affecting this setting. Users should note that port 3 may not be suitable as a work port due to this characteristic; if necessary, a four-port version of the valve can address this limitation. The DPCDLDV is interchangeable with direct-acting versions, fitting the same cavities and maintaining identical flow paths. It features Sun's floating style construction, which minimizes internal binding risks from excessive installation torque or machining variations. The valve has a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of up to 15 gpm (60 L/min). It is not bistable but capable of modulating between two positions, with maximum leakage rates at specified conditions being minimal. Additional specifications include a control pilot flow ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), adjustment via clockwise turns for increased settings, and specific torque requirements for installation and locknut adjustments. The valve's design ensures reliable performance in various applications where precise control of moderate fluid flows is required.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
- 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.
