The Sun Hydraulics DPCBLCN (DPCBLCN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds its set threshold, with additional pressure at port 3 directly affecting the setting. However, due to pressure limitations at port 3, it may not be suitable as a work port; in such cases, a 4-port version might be necessary. The DPCBLCN is interchangeable with direct-acting versions as they fit identical cavities and share flow paths. It is capable of modulating between two positions rather than being bistable. The maximum allowable pressure at port 3 is capped at 3000 psi due to fatigue strength limits, not hydraulic operating constraints. The valve incorporates Sun's floating style construction to mitigate internal binding risks from excessive installation torque or cavity machining variations. It fits a T-2A cavity in Series 2 with a capacity of up to 15 gpm (60 L/min) and factory settings established at 4 gpm (15 L/min). The DPCBLCN can withstand a maximum operating pressure of 5000 psi (350 bar) and has control pilot flow rates ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). Valve leakage is kept minimal at less than one in\u00b3/min under standard conditions. For adjustment, the valve requires up to five full clockwise turns to increase its setting, utilizing an internal hex screw size of ^5/32 inch (4 mm), while installation involves torquing the valve hex size of 1 ^1/8 inch (28.6 mm) between 45 and 50 lbf-ft (61-68 Nm).

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.
