Z2FS16 Hydraulic Flow Adjustment Control Valves

Z2FS16 Hydraulic Flow Adjustment Control Valves 

Rexroth Z2FS16 Hydraulic Flow Adjustment Control Valves  is the modular dual unidirectional Throttle Valve to control one or two of the main flow of the oil port or pilot oil flow. Two symmetrically arranged check throttle valve limits the flow in one direction, and allowing the opposite direction to flow freely. The valve can be simultaneously connected to the two oil passages of the working oil chamber. Two symmetrical way throttle valve in one direction by adjusting the size of orifice cross-sectional area to regulate the flow through the check valve and back to the oil in the other direction.

Z2FS16 Hydraulic Flow Adjustment Control Valves 
By selecting a different installation location, or different models to throttle the way of internal or external, hydraulic fluid through the throttling point ( from the valve seat and the throttle poppet constitute ) via channel filling flow ports.
The axial orifice area of the valve throttle poppet can be adjusted, so as to adjust the throttle point.
The hydraulic fluid returned from the working oil port to push the valve seat, to overcome the biasing force of the spring to move throttle poppet, allowing the free flow of the fluid.
