Rising stem ball valve

Main features: With rising stem and mechanical cam design to achieve the tilt and turn action, eliminates friction and abrasion between body seat and ball surface. Single seat design can eliminate the problem of excessive pressure trapped in the body cavity. Rising stem ball valves are widely used in those plants where are with high temperature, high pressure, frequent operation, zero leakage, emergency shutoff, hazardous medium isolation, etc. Some typical applications such as molecular sieves exchange valve, hydrogen dispenser inlet and outlet valve, emergency shutoff valve, measuring pipeline shutoff valve,etc.
