1.1.Product name:ductile iron pressure reducing valve, Ductile Iron pressure reducing valve,Ductile Iron Epoxy Coating Pressure relief/reducing Valve, pressure reducing valve
. 1.2Product introduction
This valve is designed and manufactured by our company according to the advanced product of the same type in the United States, France and China. The valve body adopts the streamlined design with less internal head loss and large flow. The transmission mode adopts the hydraulic operation, and the pipeline pressure is used to automatically control the up and down movement of valve disc, control the valve opening, and adjust the downstream pressure, so as to maintain the downstream pressure above the pilot valve spring set value. When the downstream pressure exceeds the set value, the valve will shut down automatically, and guarantee the constant outlet pressure.
The product is the ideal product used for domestic water, fire system and water supply system.
2. Structural
The valve consists of the main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge etc. The pilot valve, needle valve, ball valve and pressure gauge are connected to the main valve with pipe, so it is collectively called as the pipe control system, as shown in the below picture.
1. Needle valve; 2. Pressure reducing valve; 3. Ball valve
