MODEL
DVCO
3-way, vent-to-operate, directional valve with drain to port 4 and integral T-8A
control cavity (1 blocked, 2 to 3 open)
SERIES 2 / CAPACITY: 60 L/min. / CAVITY: T-22A
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.

TECHNICAL FEATURES
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.
PERFORMANCE CURVES
Compound cartridge (pilot and main stage) assembly information is provided for reference only. Cartridges must be ordered separately and assembled at
point of use.
