Pneumatic butterfly valve is in the industrial production line of a control component, it belongs to automatic control valve, no manual operation, so this kind of valve is usually used in the environment is not suitable for manual operation.
Pneumatic butterfly valve through the locator, solenoid valve and other devices to absorb dry, lubricated gas, and then transfer these gases to the pneumatic actuator cylinder, used to form a driving pneumatic actuator work gas source. When the air source in the cylinder body passes into the air chamber of the pneumatic actuator, the air pressure ACTS on the piston, and the thrust generated drives the output shaft to rotate. Drive stem and disc rotation at the same time to complete a butterfly valve opening and closing action.
Add a valve positioner to the pneumatic butterfly valve can also achieve accurate opening adjustment butterfly valve. In addition, intelligent locator can also be used to connect with the field bus, so as to detect the working state of pneumatic butterfly valve, and provide diagnosis.
