The Sun Hydraulics DVBO8FV (DVBO8FV) is a versatile 3-way directional cartridge valve with an integral pilot control cavity, designed to operate as a standalone unit or to actuate larger pilot-operated directional cartridges or logic elements. This valve functions by shifting when there is flow through the pilot control cartridge installed in the T8A cavity. It allows bidirectional flow between ports 2 and 3, and between ports 1 and 2, with port 3 serving as a potential work port. The valve requires a pressure source at port 1 relative to port 4 to shift effectively. Notably, this valve is not bistable but can modulate between two positions. The DVBO8FV features Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations in the cavity/cartridge. It has a capacity of 7 gpm (28 L/min) and can handle a maximum operating pressure of up to 5000 psi (350 bar). The valve's 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 minimal at just 2 in\u00b3/min (1000 psi). For installation, the main stage valve should be torqued correctly before installing the T8A pilot control section into it. The DVBO8FV accommodates various pilot control options that can be incorporated directly into the end of the directional cartridge via the T8A cavity; these include solenoid operation, air pilot operation, and hydraulic pilot operation\u2014all sold separately. The valve has a hex size of 7/8 inches (22.2 mm) and requires an installation torque of between 30-35 lbf ft (41-47 Nm). It weighs approximately .50 lb (0.25 kg) and uses Viton seal kits, ensuring durability in various applications requiring reliable directional control within hydraulic systems.

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.
- 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.
- The flow path between port 1 and port 2 is bidirectional.
- 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.
