Inch valves are used in hydrostatic propel systems of mobile machines as an override control of variable pump which is fitted with speed-dependent control.
They are produced in two-way and three-way versions.
Inch valves serve for braking or quick stop and for slow smooth take-off of a mobile machine when the pump main control is not in function.
Two-way inch valves IV 08-2, IV 08-2H
Inching function represents controlled connection of pump control pressure with tank. The valve is operated either mechanically (IV 08-2) or hydraulically (IV 08-2H).
Three-way inch valve IV 08-3
Inching function represents controlled equalizing of pressure in the pump servo-cylinder.
