The Sun Hydraulics DVCB8FN (DVCB8FN) is a normally closed, 2-way directional cartridge valve featuring an integral pilot control cavity. It is designed for standalone use or to actuate larger pilot-operated directional cartridges or logic elements. The valve operates by shifting when there is flow through the pilot control cartridge installed in the T8A cavity. Proper installation requires first securing the main stage valve to its torque specification, followed by the T8A pilot control section. This valve is not bistable and can modulate between two positions, with pressure at port 3 potentially opposing valve opening, making port 3 unsuitable as a work port in some circuits; a 4-port version may be required for such applications. A pressure source at port 1 relative to port 3 is necessary for shifting the valve. The design allows for direct incorporation of an 8 control option pilot control valve into the directional cartridge via the T8A cavity, with options including solenoid, air pilot, and hydraulic pilot operations\u2014sold separately as Pilot Control Cartridges. The DVCB8FN utilizes Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. Key specifications include a T2A cavity, series 2 classification, a capacity of up to 15 gpm (60 L/min), and 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), with maximum leakage at 110 SUS (24 cSt) being 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). The valve features a hex size of 1-1/8 inches (28.6 mm) and requires an installation torque of 45-50 lbf-ft (61-68 Nm). The model weighs approximately .50 lb (.25 kg) and uses a Viton seal kit with part number 990202006.

This valve is a normally closed, 2-way directional cartridge that incorporates an integral pilot control cavity. It may be used by itself or to actuate larger pilot-operated directional cartridges or logic elements. The valve shifts when there is flow through the pilot control cartridge installed in the T-8A cavity.
- NOTE: The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- Pressure at port 3 may oppose the opening 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.
- There must be a pressure source at port 1, relative to port 3, to shift the valve.
- The -8 control option allows the pilot control valve to be incorporated directly into the end of the directional cartridge via the T-8A cavity. These pilot control cartridges are sold separately and include solenoid operation, air pilot operation, and hydraulic pilot operation. See Pilot Control Cartridges.
- Leakage listed in technical data is for each path.
- 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.
