Originally patented in the late 1970’s, the Dome Valve® is unique in its ability to open and close with a tight pressure seal in pneumatic conveying systems for abrasive materials. No other valve can achieve as long of a life in harsh environments like the Dome Valve®. We are the original designers and patent holders of the Dome Valve®.
