Pneumatic high vacuum butterfly valve

The pneumatic actuator of GIQ-AB series pneumatic high vacuum butterfly valve is powered by compressed air. The direction of the air path is changed by the electromagnetic reversing valve, the mechanical transmission of the piston rack and gear is driven, and the angular stroke output torque is used to drive the butterfly valve to open and close, so as to achieve the purpose of connecting or cutting off the air flow in the vacuum pipeline. The valve plate of the valve adopts a clamping structure, which clamps the sealing ring of the valve plate, and has the function of fine-tuning the main seal. It is a new type of pneumatic high-vacuum butterfly valve controlled by a pneumatic actuator, which is divided into double-acting and single-acting (spring return) cylinders. Feedback signal device and electric valve positioner are optional. The applicable working medium is air and non-corrosive gas.
