Rectangular Vacuum Valves

Bellows-sealed rectangular gate valves feature a patented L-motion link assembly and dual shafts without springs in the actuator to enable faster, smoother actuation with significantly reduced vibration. This design also results in less wear, less particulate generation and faster cycle times. The dust seal on the vacuum side of the bonnet flange virtually eliminates process particulate from entering the bellows, leading to long cycle life.
