Eaton Vickers® K(B)FD/TG4V proportional valves are

KBFD/TG4V-5

designed to provide a controlled oil flow in direct proportion to a command signal. They are available inA range of proportional directional and throttle valves with integral control electronics

.

Factory-set adjustments of

two types; a double solenoid version that will provide gain, spool deadband compensation and offset ensure reversible flow to an actuator and a single solenoid throttle consistent repeatability valve-to-valve

.

version that provides a single direction of flow. The only electrical inputs required are power supply (24V) Hydrostats are available for load compensation and parallel and a voltage command signal of ±10V or 4-20 mA

.

Theflow path modules are available that will boost the flow amplifier is housed in a robust metal enclosure, sealed capacity of single solenoid throttle versions to nearly twice against ingress of water and other fluids

.

Electrical that of the standard valve. connections are via a standard 7-pin plug

.

Additionally, both of these valve types can be supplied with or without an integral amplifier built directly onto the valve. A spool position monitor pin allows the function of the valve to be electrically monitored

.

Ramp functions, if required, can be generated externally
