The Sun Hydraulics DPCBOHN (DPCBOHN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile in application and can be used independently or 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 being directly additive to this setting. This feature may restrict the use of port 3 as a work port in certain circuit designs, suggesting that a four-port version might be more suitable for such applications. The DPCBOHN is not bistable and can modulate between two positions, offering flexibility in control. This valve incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It fits into cavity T2A and belongs to series 2, with a capacity of 15 gpm (60 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). The control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), and the maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). The adjustment mechanism allows for up to 5.5 clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments ensuring secure operation. With a model weight of approximately .60 lb (0.30 kg), this cartridge valve offers reliable performance in hydraulic systems requiring precise pressure modulation without excessive pilot flow consumption above the valve setting limits.

Normally closed, 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.
