The Sun Hydraulics DVBN8FV (DVBN8FV) is a normally closed, 2-way directional cartridge valve featuring an integral pilot control cavity. This versatile component can function independently or in conjunction with larger pilot-operated directional cartridges or logic elements. The valve shifts when flow occurs through the pilot control cartridge installed in the T8A cavity, offering bidirectional flow between port 2 and port 3. Port 3 can be utilized as a work port, and the valve requires a pressure source at port 1 relative to port 4 for shifting. Notably, this valve is not bistable; it modulates between two positions and incorporates Sun's floating style construction to minimize internal binding due to excessive torque or machining variations. The DVBN8FV supports a capacity of 7 gpm (28 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It features a T21A cavity and requires specific installation torque values: main stage valve at 30-35 lbf ft (41-47 Nm) followed by the T8A pilot control section. The maximum allowable leakage at 110 SUS (24 cSt) is specified as 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). The valve weighs approximately .50 lb (.25 kg) and utilizes Viton seal kits for cartridge sealing. For enhanced functionality, various pilot control cartridges can be incorporated directly into the end of the directional cartridge via the T8A cavity, including options for solenoid, air pilot, or hydraulic pilot operation. These control cartridges are sold separately. The DVBN8FV is designed with a hex size of .78 inches (22.2 mm), ensuring compatibility with standard installation tools.

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.
- Port 3 can be used as a work port.
- The flow path between port 2 and port 3 is bidirectional.
- 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.
- There must be a pressure source at port 1, relative to port 4, 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.
