Product Details

Y43W/H steam pressure reducing valve

Product overview/Product outline

Y43W/H series steam pressure reducing valve is suitable for steam pipeline. Through the adjustment of the pressure reducing valve, the inlet pressure can be reduced to a certain required outlet pressure. When the inlet pressure or flow rate changes, the pressure reducing valve relies on the energy of the medium itself to automatically meet the predetermined value after the valve, so as to adapt to the requirements of the working condition.
