The Sun Hydraulics DVCN8FN (DVCN8FN) is a normally closed, two-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. The shifting mechanism of the valve is activated by flow through the pilot control cartridge installed in the T8A cavity. It allows bidirectional flow between port 2 and port 3, with port 3 also serving as a work port. Installation requires specific torque values for both the main stage valve and the T8A pilot control section. The DVCN8FN is not bistable but can modulate between two positions, requiring a pressure source at port 1 relative to port 4 to shift. The design incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. With a capacity of 15 gpm (60 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve offers robust performance for demanding applications. The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The DVCN8FN fits into a T22A cavity and has a series designation of '2'. Its installation torque ranges from 45 to 50 lbf-ft (61 to 68 Nm), with an overall model weight of .50 lb (0.25 kg). A Viton seal kit is available under part number 990022006 for maintenance needs.

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.
