Product description
The valve type Z.FG is a throttle valve in sandwich plate design. It is used for the flow limitation of one or two actuator ports.
Two symmetrically arranged throttle valves limit flows in both directions.
In case of throttling, the hydraulic fluid is directed through channel A1 or B1 via throttling point (1) formed by the control edge (2) and the throttle spool (3.1) to actuator A2 or B2. The throttle spool (3.1) can be axially adjusted via the spindle (4) for adjustment of the flow via the throttling point (1). The flow depends on the pressure differential and viscosity.
In version "P", throttling is realized in channel P. Channels A and B have free flow. In version "A" or "B", the channel without throttling has free flow.
