centered with solenoid A removed. F
models are spring offset to port A and
respond to an increasing signal by
reducing the flow rate. The KTG’s spool
can be infiniy positioned to achieve
throttling (restriction) of the fluid flow.
The primary function of these valves is to
direct and meter fluid flow in proportion to
current received by the solenoid. This fluid
flow controls the velocity, direction, and
acceleration

or deceleration of a work cylinder
or fluid motor.
These valves are designed to fill the
performance gap between conventional
control actuator direction and speed while
eliminating shock caused by rapid
acceleration and deceleration of machine
loads.
In addition to improving machine
performance and life, these proportional
valves substantially simplify system design
by combining direction and flow control
capabilities in one package that mounts to
a standard NFPA/ISO subplate or manifold
interface.
The valve can also be readily tailored to a

vast array of applications by specifying the
KADG and KATG Valves
The above description of KDG and KTG
valves also applies to KADG and KATG
valves, with one exception. “KA” valves
have an integral amplifier, whereas KDG
and KTG valves do not.
The control amplifier of KA models is
housed in a sturdy metal enclosure
directly on, and prewired to, the valve.
Factory-set adjustments of gain, balancing
deadband and dither ensure high
repeatability valve-to-valve. The only
electrical inputs required are power
supply (24V) and a voltage command
