The Sun Hydraulics DVBO8FN (DVBO8FN) is a 3-way directional cartridge valve featuring an integral pilot control cavity, designed for versatile hydraulic applications. This valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic elements. It operates by shifting when flow occurs through the pilot control cartridge installed in the T8A cavity. Port 3 serves as a work port, with bidirectional flow paths between ports 2 and 3, as well as between ports 1 and 2. The valve requires a pressure source at port 1 relative to port 4 to shift effectively. It incorporates an innovative Sun floating style construction to minimize internal part binding due to excessive installation torque or machining variations. The valve's specifications include a T21A cavity, series 1 classification, and a capacity of up to 7 gallons per minute (28 liters per minute). It can withstand a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 cubic inches per minute (0.11 to 0.16 liters per minute), with maximum valve leakage at specified conditions being approximately 2 cubic inches per minute (30 cc/min) at 1000 psi (70 bar). The DVBO8FN is not bistable but capable of modulating between two positions, and it supports various pilot control options available separately, including solenoid, air, and hydraulic operations within the T8A cavity. For installation, it requires specific torque values: the main stage valve should be torqued first followed by the T8A pilot section. The valve's hex size is .78 inches (22.2 mm), with installation torque ranging from 30 to 35 lbf-ft (41 to 47 Nm). The model weighs approximately .50 lb (.25 kg) and utilizes Viton seal kits for maintenance needs.

This valve is a, 3-way directional cartridge (1 blocked, 2 to 3 open) 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.
- The flow path between port 1 and port 2 is bidirectional.
- 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.
