(,) Structural features and uses

This series of stainless steel pressure reducing valves are pilot piston type pressure reducing valves. It consists of two parts: main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, valve disc, diaphragm, spring, adjusting spring and other parts. This product has made great improvements on the basis of ordinary pressure reducing valves, enlarging the piston area and changing the throttling structure. The sealing form has been changed, the flow area has been enlarged, etc., thereby greatly improving the performance in terms of sensitivity, flow rate, life, etc. This product is mainly used in steam pipelines, suitable for steam pipelines with large flow rates, large flow changes, and large changes in inlet pressure.
