Product description
The valve type Z1FG is a throttle valve in sandwich plate design. It serves for flow limitation in channel P.
In case of throttling, the hydraulic fluid is directed through channel P1 via throttling point (1) formed by the control edge (2) and the throttle spool (3) to port P2. The throttle spool (3) can be axially adjusted via the spindle (4) for adjustment of the flow via the throttling point (1). The adjustment stroke is limited by the pin (5) in both directions. The flow depends on the pressure differential and viscosity.
