The Sun Hydraulics DPCALWV (DPCALWV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or serve to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the preset threshold, with pressure at port 3 directly adding to the setting. However, due to this characteristic, port 3 may not be suitable as a work port in certain circuits; a 4-port version of this valve could address such concerns. This valve is interchangeable with direct-acting versions, sharing cavity compatibility and flow paths. It features modulation capabilities between two positions rather than bistability, and its maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength constraints. Pilot flow considerations arise when pilot pressure exceeds the valve setting; if excessive pilot consumption occurs, switching to a direct-acting version could be advantageous. The DPCALWV incorporates Sun's floating style construction, minimizing internal part binding risks due to installation torque or machining variations. It fits a T2A cavity from Series 2 and offers a capacity of up to 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 valve leakage is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The adjustment mechanism allows for increasing settings through up to five clockwise turns, with specified torque values for installation and locknut adjustments ensuring secure operation.

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 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.
