The Basement Gate Valve (BGV) enables dry vacuum pumps operating in harsh processes to be kept running during maintenance, maximizing reliability and up-time. The valves have been designed with a wedge sealing system that avoids the complex mechanism of traditional gate valves. The benefit is that no oil, grease, or moving parts are within the vacuum, thereby reducing the risk of the mechanism being damaged by contamination of the lubrication in dusty processes. The simplified gate sealing design makes for quick and easy maintenance. Both manual and pneumatic valves are available.
