The Sun Hydraulics DVBM8FV (DVBM8FV) is a normally open, 2-way directional cartridge valve featuring an integral pilot control cavity. This versatile component can function independently or be utilized to actuate larger pilot-operated directional cartridges or logic elements. The valve transitions when flow occurs through the pilot control cartridge installed in the T8A cavity. Port 3 serves as a work port, with a bidirectional flow path between port 2 and port 3. Installation requires precise torque application: first for the main stage valve, followed by the T8A pilot control section. The valve is not bistable and modulates between two positions, necessitating a pressure source at port 1 relative to port 4 for shifting. The \"8\" control option allows direct incorporation of the pilot control valve into the directional cartridge via the T8A cavity, with separate purchase options including solenoid, air pilot, and hydraulic pilot operations. The DVBM8FV employs Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. It fits into a T-21A cavity and belongs to Series 1 with a capacity of 7 gpm (28 L/min) and 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), while maximum valve leakage at 110 SUS (24 cSt) is specified at 2 in\u00b3/min (1000 psi or approximately 30 cc/min at 70 bar). Its hex size measures .78 inches (22.2 mm), requiring an installation torque of 30-35 lbf ft (41-47 Nm). The model weighs .50 lb (.25 kg) and utilizes Viton seal kits for maintenance.

This valve is a normally open, 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.
- 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.
- 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.
