GDQ-KF series straight-through pneumatic high-vacuum flapper valve uses compressed air as the power, changes the direction of the air path through the electromagnetic reversing valve, pushes the cylinder piston to move up and down, drives the valve stem to move up and down, and makes the valve plate open or close, so as to achieve The purpose of turning on or off the air flow in the vacuum system. The applicable working medium is air and non-corrosive gas.

GDQ-JS three-way pneumatic high vacuum flapper valve uses compressed air as the power to change the direction of airflow by controlling pneumatic components, with two-way interface and cylinder drive to make the flapper valve open and close, which is used to connect or cut off Airflow in vacuum lines. The applicable working medium is air and non-corrosive gas.

GD-J (b) series manual high-vacuum flapper valve is one of the important components in the vacuum system. The transmission part of the valve adopts a threaded structure, and the valve plate is opened and closed by manual rotation of the handwheel. Applicable media are air and non-corrosive gases.

GU series vacuum (pressure) ball valve is suitable for connecting or cutting off the medium flow in the pipeline in the vacuum system. The valve is a straight-through manual ball valve, which is sealed by a spherical surface, so it can be used in both vacuum and low pressure conditions, and can be installed at any position. The applicable working medium is gas or liquid with acid and alkali.
