Imported pneumatic high vacuum butterfly valve (Germany Robert brand)
Product introduction
The pneumatic actuator of the German Robert imported pneumatic high vacuum butterfly valve is powered by compressed air and changes the air path through an electromagnetic reversing valve. direction, promotes the mechanical movement of the piston rack and gear, and uses the angular stroke output torque to drive the butterfly valve to open and close. In order to achieve the purpose of connecting or cutting off the air flow in the vacuum pipeline, it is a new type of pneumatic butterfly valve controlled by a pneumatic actuator, which is divided into double-acting and single-acting (spring return) cylinders. Optional feedback signal device and electrical valve positioner are available.
