| Trunnion Ball Valve are the three different types of rotary valves used in industrial plants. |
| They are widely used in fluid-handling systems for flow control.These types of rotary valves are suitable for corrosive applications. |
| They are used in detergent, pharmaceutical, chemical, rubber, pulp and paper plants, water treatment systems, textile mills |
| And food processing plants, In general, ball valves offer many advantages when contrasted with other valve types. |
| 1. Free leakage of body Sealed construction |
| The connective position of valve body and bonnet is double sealed by gasket and O-ring,on this base,such factors as fire, |
| High temperature,shock and uneven opening or closing of the torque all can't induce external leakage. |
| 2. Low torque in operation |
| The self-lubricated bearings are installed at the friction of stem,resulting in wear resistance,fiexibility of operation and low torque. |
| When ball is full open or close position,the transmitter substance in center cavity of body can be released by drainage and emptying devices. |
| In addition,the over loaded pressure in the center cavity of valve can be released to low pressure end by self relief seat. |
