The Sun Hydraulics DVCN8FV (DVCN8FV) is a normally closed, 2-way directional cartridge valve with an integral pilot control cavity, designed for versatile hydraulic applications. It can function independently or be used to actuate larger pilot-operated directional cartridges or logic elements. The valve operates by shifting when flow is present through the pilot control cartridge installed in the T8A cavity. Port 3 serves as a work port with a bidirectional flow path between ports 2 and 3. Installation requires precise torque application: first, the main stage valve, followed by the T8A pilot control section. The valve is not bistable but can modulate between its two positions; a pressure source at port 1 relative to port 4 is necessary for operation. The design includes an option for incorporating the pilot control valve directly into the directional cartridge via the T8A cavity, with separate purchase options for solenoid, air, or hydraulic pilot operation controls. This valve features Sun's floating style construction to reduce internal part binding due to excessive installation torque or machining variations in cavity/cartridge production. It fits within a T22A cavity and belongs to Series 2 with a capacity of 15 gpm (60 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges between 7 and 10 in\u00b3/min (0.11 \u2013 0.16 L/min), while maximum valve leakage at 110 SUS (24 cSt) is specified at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The valve has a hex size of 1-1/8 inches (28.6 mm) and requires an installation torque of between 45 and 50 lbf-ft (61 \u2013 68 Nm). Weighing approximately .50 lb (.25 kg), it utilizes Viton seal kits available under part number 990022006.

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.
- 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.
