The Sun Hydraulics DVBB8FV (DVBB8FV) is a normally closed, 2-way directional cartridge valve featuring an integral pilot control cavity. This versatile valve can function independently or in conjunction with 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. Notably, this valve is not bistable and can modulate between two positions. The design requires a pressure source at port 1 relative to port 3 to facilitate valve shifting, although pressure at port 3 may counteract opening, potentially limiting its use as a work port. For applications where this is a concern, a 4-port version may be preferable. The DVBB8FV incorporates Sun's floating style construction, which helps minimize internal part binding due to excessive installation torque or machining variations. It fits into the T11A cavity and belongs to Series 1 with a capacity of up to 7 gpm (28 L/min) and can withstand 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 valve leakage at specified conditions being minimal at 2 in\u00b3/min (30 cc/min). The valve's hex size is .78 inches (22.2 mm), requiring an installation torque between 30 and 35 lbf\u00b7ft (41 and 47 Nm). Weighing only .50 lb (.25 kg), this model also supports various pilot control options\u2014sold separately\u2014such as solenoid, air pilot, or hydraulic pilot operation for enhanced flexibility in diverse hydraulic applications.

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.
