The Sun Hydraulics DVBC8FN (DVBC8FN) is a 3-way directional cartridge valve designed with an integral pilot control cavity. This versatile valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic elements. The valve shifts when flow occurs through the pilot control cartridge installed in the T8A cavity, allowing it to modulate between two positions, though it is not bistable. It features a bidirectional flow path between port 1 and port 2, while pressure at port 3 may affect the valve's opening, potentially limiting its use as a work port. For applications requiring port 3 as a work port, a 4-port version of this valve is recommended. The DVBC8FN incorporates Sun's floating style construction to minimize internal binding due to excessive torque or machining variations. It has a cavity size of T11A and belongs to Series 1, with a capacity of handling up to 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), and the maximum leakage at 110 SUS (24 cSt) is specified at 2 in\u00b3/min (1000 psi or approximately 30 cc/min at 70 bar). For optimal performance, ensure proper installation torque values: the main stage valve should be torqued between 30-35 lbf ft (41-47 Nm), and the T8A pilot control section should be secured accordingly. The valve's hex size measures .78 inches (22.2 mm), and it weighs .50 lbs (.25 kg). Seal kits are available with Viton material under part number 990011006 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.
- 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.
