The Sun Hydraulics DVBP8FN (DVBP8FN) is a 3-way directional cartridge valve designed to manage fluid flow effectively in hydraulic systems. It features an integral pilot control cavity, allowing it to function independently or in conjunction with 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, which can be solenoid, air, or hydraulically operated and is sold separately. This model supports bidirectional flow between ports 1 and 2 and ports 2 and 3, with port 3 available as a work port. It requires a pressure source at port 1 relative to port 4 for operation. The DVBP8FN incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. With a capacity of up to 7 gallons per minute (28 liters per minute) and a maximum operating pressure of 5000 psi (350 bar), this valve suits high-pressure applications. It has a maximum valve leakage rate of 2 cubic inches per minute at 1000 psi (30 cc/min at 70 bar). The valve's installation requires specific torque values: the main stage should be torqued between 30-35 lbf ft (41-47 Nm), followed by the T8A pilot control section. This model weighs approximately .50 lb (0.25 kg) and fits into a T21A cavity with a hex size of .78 inches (22.2 mm). For maintenance, it uses Viton seal kits under part number 990021006. The DVBP8FN is not bistable but can modulate between two positions, providing reliable performance for various hydraulic applications requiring precise flow control and modulation capabilities.

This valve is a, 3-way directional cartridge (1 to 2 open, 3 blocked) 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.
