The Sun Hydraulics DVBB8FN (DVBB8FN) is a normally closed, 2-way directional cartridge valve featuring an integral pilot control cavity. This versatile valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic elements. It operates by shifting when there is flow through the pilot control cartridge installed in the T8A cavity. It's important to note that this valve is not bistable and can modulate between two positions. Installation should begin with the main stage valve torqued correctly, followed by the T8A pilot control section. The DVBB8FN requires a pressure source at port 1 relative to port 3 for operation, though pressure at port 3 may oppose valve opening, potentially limiting its use as a work port. For applications where this is a concern, consider the 4-port version of this valve. The design incorporates Sun's floating style construction to minimize internal binding from excessive torque or machining variations. Key specifications include a T11A cavity, Series 1 classification, and a capacity of 7 gpm (28 L/min) with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and maximum leakage is rated at 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). The valve has a hex size of 7/8 inch (22.2 mm) and requires an installation torque between 30 and 35 lbf ft (41 to 47 Nm). It weighs approximately .50 lb (.25 kg) and uses Viton seal kit number 990011006 for maintenance.

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.
- 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.
- 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.
