Features
The Pneumatic Baffle plate valve of high vacuum is driven by compressed air through electromagnetic commutator to change direction of the gas pathway for the implementation of tanks driven alternatives valves open and close movement, or in a vacuum system to cut off or connect through air currents purposes. Working medium is applicable to non-corrosive gases and air. Pneumatic valves at high vacuum back plate are classed by axis structure into GDQ-J type rubber sealed and GDQ-Jb type corrugated pipes sealed two. GDQ-J for corner Link patterns, GDQ-S to bring the three links to pumping mouth patterns.

Features
The Baffle plate valve of high vacuum is an Integral vacuum system which is an important component in the vacuum system for cutting or connected by air currents. Working medium is applicable to non-corrosive gases and air. High vacuum valves baffle plate by obdurated axes can be classed as GD-J type rubber sealed and GD-Jb type corrugated pipes sealed two. GD-J for Kok Link patterns, GD-S to bring the three links to pumping mouth patterns.
