CHA Industries uses a vertical sealing plane on all valves. This design is particularly important on the high vacuum valve. Falling particles will not land on the sealing surface, keeping it leak tight. For less wear and greater reliability, the CHA high-vacuum valve has fewer moving parts than any other in the industry. It also has less surface area than is normally found in valves using a siding gate.
