Process Description
 Reducing valve, Pressure reducing valve 
 
 There are two types of reducing valves, direct acting and pilot operated. Both use globe or angle style bodies. Reducing valves used on smaller piping diameter units are cast from brass; larger piping diameter units are made from ductile iron. Direct acting valves, the more popular type of a water pressure reducing valves, consist of globe-type bodies with a spring-loaded, heat-resistant diaphragm connected to the outlet of the valve that acts upon a spring. This spring holds a pre-set tension on the valve seat installed with a pressure equalizing mechanism for precise water pressure control.

 Valves are widely used in the field of water treating equipments industry, chemical equipments industry, petrifaction industry, petroleum equipment industry, papermaking industry, mining equipment industry, electricity equipment industry, liquefied gas equipment industry, food equipment industry, pharmacy equipment industry, water supply and drainage system, mechanical equipment valve, electronic industry valve, civil construction valves, industry pipeline valves, GE parts, industry equipments, fire fighting system, filter equipments, environmental protection equipments. Besides these, they can also be used for nuclear power industry, thermal power equipments, building industry and the special industries.

 Usually used material for valves: gray iron, ductile iron, WCB, LCC, carbon steel, casting steel, SS304, SS316, CF8, CF8M、CF3、CF3M, duplex stainless steel and special steel. Pressure grade: 0.6~32.0Mpa, inside nominal diameter: DN15~DN2000, applicable temperture:-150℃~+700℃.

 Reducing Valve Technological Process


 We will produce valves according to the International Production Standard. All valves and it's components will be tested, including pressure testing, tightness testing and whole body debugging testing. All valves will have to pass the above testings before delivery. We warmly welcome customer representatives to come to inspect the valves any time!
 Our company is export-oriented, and the Valves have already been sold to Australia, United States, Canada, UK, (Britain, England), Holland, France, Germany, Denmark, Sweden, Finland, Russia, Spain, Portugal. Italy, etc.
