| Check valve, clack valve |
 |
| A check valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, and/or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. |
| 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℃. |
