The Sun Hydraulics DVBD8FN (Material Number: DVBD8FN) is a 3-way directional cartridge valve designed for versatile hydraulic applications. This valve features a configuration where port 1 is open to port 2, with port 3 blocked, and incorporates an integral pilot control cavity. It can function independently or be used to actuate larger pilot-operated directional cartridges or logic elements. The valve operation is initiated by flow through a pilot control cartridge installed in the T8A cavity, which allows for modulation between two positions rather than bistable operation. The bidirectional flow path between ports 1 and 2 offers flexibility in circuit design, though pressure at port 3 can oppose valve opening, potentially limiting its use as a work port. A pressure source at port 1 relative to port 3 is necessary for shifting the valve. The DVBD8FN supports the integration of various pilot control options directly into the end of the directional cartridge via the T8A cavity, with options including solenoid, air pilot, and hydraulic pilot operations. These pilot control cartridges are sold separately. The valve's construction employs Sun's floating style design to minimize internal part binding due to excessive installation torque or machining variations. Key specifications include a T11A cavity series, a capacity of 7 gpm (28 L/min), and a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum leakage at specified conditions being limited to 2 in\u00b3/min (30 cc/min). Installation requires a torque range of 30-35 lbf ft (41-47 Nm), and the model weighs approximately .50 lb (0.25 kg). A Viton seal kit is available for maintenance purposes under part number 990011006.

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.
- 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.
- 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.
