The Sun Hydraulics DVBA8FN (DVBA8FN) is a versatile, normally open, 2-way directional cartridge valve featuring an integral pilot control cavity. This valve is designed for standalone use or to actuate larger pilot-operated directional cartridges or logic elements. It operates by shifting when there is flow through the pilot control cartridge installed in the T8A cavity. A key feature of this valve is its modulation capability between two positions rather than being bistable. Installation requires specific torque values: first for the main stage valve and then for the T8A pilot control section. It's important to note that pressure at port 3 can oppose valve opening, making it potentially unsuitable as a work port unless using the 4-port version of this valve. The DVBA8FN requires a pressure source at port 1 relative to port 3 for operation. This model incorporates Sun's floating style construction, which minimizes internal binding due to excessive installation torque or machining variations. It has a cavity size of T-11A, belongs to series 1, and offers a capacity of up to 7 gpm (28 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with a control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Leakage rates at maximum conditions are specified as 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). The valve's hex size measures 7/8 inches (22.2 mm), and the installation torque ranges between 30 and 35 lbf ft (41 to 47 Nm). The model weighs approximately .50 lb (0.25 kg) and includes a Viton seal kit option under part number 990011006.

This valve is a normally open, 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.
