product description 

The pressure reducing valve is mainly used for steam pipe, from the role of decompression regulator. Pilot-dependent valve. The main valve and pilot valve composed of two parts. The main valve from the valve seat, the main valve disk, piston, spring and other components. Pilot valve mainly by the valve seat, disc, diaphragm, spring, adjusting spring and other components. This product has been greatly improved on the basis of ordinary pressure reducing valve, increasing the piston area and changing the throttling structure. Change the seal form, increase the over-current area, etc., which greatly improve the performance in terms of improving sensitivity, flow, life and so on. This product is mainly used for steam pipe, suitable for large flow rate changes, large changes in the inlet pressure of the steam pipeline.
