NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.

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.

TECHNICAL FEATURES

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.

Pressure at port 3 may oppose the opening of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4

port version of this valve may be a solution.

There must be a pressure source at port 1, relative to port 3, 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.
