Pneumatic high vacuum butterfly valve

The pneumatic actuator of GIQ-B series pneumatic high-vacuum butterfly valve is powered by compressed air, changes the direction of the air path through the electromagnetic reversing valve, promotes the mechanical transmission of the piston rack and gear, and drives the butterfly valve with angular stroke output torque. Opening and closing movement. 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, and feedback signal devices and electric valve positioning are optional. device. The applicable working medium is air and non-corrosive gas.
