| Control Valve Description |
 |
| Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.The opening or closing of control valves is usually done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on electric, or pneumatic signals. |
| 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℃. |
