ZKY42X Diaphragm Type Pressure Reducing Valve is one type of adjustable pressure reducing valves, which means the outlet pressure can be adjusted according to requirements. After setting up the outlet pressure value, the outlet pressure will reduce and keep on the preset one, which will not be changed because of the change of the pressure or flow before valve.
ZKY42X Diaphragm Type Pressure Reducing Valve has quality materials, reliable performance and long service life. It is applicable to be mounted on the pipeline (≥DN50).
