Features

â‘ The valve body adopts an integrated structure, realizing an ultra-short flange distance. The overall weight is greatly reduced, to about 50% of that of conventional ball valves of the same type.
â‘¡ Double-sided spherical sealing, meeting the zero-leakage standard.
â‘¢ Ball core passage is available in rectangular, V-shaped and O-shaped options.â‘£ Single-acting pneumatic piston actuator with spring return function, which automatically closes the valve in case of sudden air supply failure.
