The pneumatic actuator drives the disc to rotate 90 degrees through the air source pressure. According to the working mode, it can be divided into two-position type and intelligent regulating type. That is, it can be used for two-position control to fully open or close the valve, or a valve positioner can be added to the actuator and the corresponding signal can be input to adjust the disc of the pneumatic butterfly valve from 0 to 90 degrees arbitrarily.\u003c\/p\u003e","brand":"PROTEC GAS","offers":[{"title":"Default Title","offer_id":42811558559821,"sku":null,"price":2300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/9089\/0829\/files\/Screenshot2026-03-23165015.png?v=1774306303","url":"https:\/\/protecgas.com\/products\/pneumatic-butterfly-valve","provider":"PROTEC GAS","version":"1.0","type":"link"}
