The Sun Hydraulics DPCALBV (DPCALBV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be used independently or to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 exceeds the set threshold, with pressure at port 3 directly influencing this setting. However, due to fatigue strength limits, maximum pressure at port 3 should not exceed 3000 psi (210 bar). The DPCALBV is not bistable and can modulate between two positions. It features Sun's floating style construction to reduce the risk of internal binding from excessive torque or machining variations. This valve fits into a T2A cavity and belongs to series 2 with a capacity of 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 up to 5000 psi (350 bar). The control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), while maximum valve leakage at viscosity levels of 110 SUS (24 cSt) is limited to 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). The adjustment for increasing the setting involves approximately five full clockwise turns. Installation requires specific torque values: valve installation torque should be between 45 and 50 lbf-ft (61-68 Nm), while locknut torque ranges from 80 to 90 lbf-in (9-10 Nm). The valve's hex size is approximately \\(1 \\frac{1}{8}\\) inches (28.6 mm), with an adjustment screw internal hex size of \\(5/32\\) inches (4 mm), and locknut hex size of \\(9/16\\) inches (15 mm). Weighing just .60 lb (.30 kg), it also accommodates Viton seal kits for enhanced durability and performance in various hydraulic applications.

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.
