|
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the butterfly valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc of butterfly valve is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of butterfly valve position.

| 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℃. |
| 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. |
