Overview
The GDQ-J series pneumatic high vacuum baffle valve is powered by compressed air and changes the direction of the air path through an electromagnetic directional valve. It pushes the cylinder piston up and down, drives the valve stem up and down, and opens or closes the valve plate, thereby achieving the purpose of connecting or cutting off the airflow in the vacuum system

The GDQ-J series pneumatic high vacuum baffle valve is powered by compressed air and changes the direction of the air path through an electromagnetic directional valve, pushing the cylinder piston up and down and driving the valve stem up and down to open or close the valve plate, thereby achieving the purpose of connecting or cutting off the airflow in the vacuum system. Pneumatic high vacuum baffle valves can be divided into two types based on their shaft seal structure: GDQ-J rubber seals and GDQ-J (b) bellows seals. The GDQ-J type is a corner pass type, and the GDQ-S type is a three-way type with a pre extraction port.
The applicable working medium is air and non corrosive gases.
