Pneumatic Metal Seated Ball Valve

ALIS Valves offers Pneumatic Metal Seated Ball Valves for industrial applications requiring reliable flow isolation, automated operation and durable performance under demanding process conditions. These valves feature a spherical ball with a central bore that rotates to open or close the flow passage, providing effective on-off control for compatible process media. The metal-to-metal seating arrangement uses metallic sealing surfaces designed to withstand demanding operating conditions, including applications where elevated temperatures, abrasive media or conventional soft-seat limitations may be concerns. A pneumatic actuator uses compressed air to operate the ball, enabling remote control and integration with industrial automation and process control systems. Depending on the application, the valve body, ball, seat materials and surface treatments can be selected to suit the required pressure, temperature and process media. Suitable actuator configurations and control accessories can also be specified according to the required operating function.

Pneumatic Metal Seated Ball Valves are used in oil and gas facilities, refineries, petrochemical plants, power generation units, steel manufacturing and other industrial systems requiring robust pipeline isolation. Depending on the selected materials, pressure rating and sealing configuration, they can be specified for compatible liquids, gases and other process media within their rated operating limits. Important selection factors include valve size, working pressure, operating temperature, process media, body and ball materials, metal seat design, allowable leakage rate and operating torque. Metal-seated designs may have different shut-off performance from soft-seated valves, so the required leakage class should be confirmed during specification. Buyers should also consider compressed-air supply pressure, actuator sizing, control accessories and the required fail-safe action, such as fail-open or fail-closed where applicable. Selecting the appropriate valve and pneumatic actuator combination helps support dependable isolation, automated operation and reliable performance under the intended working conditions.
