Wafer Type Metal Seated Butterfly Valve

ALIS Valves offers Wafer Type Metal Seated Butterfly Valves for industrial applications requiring durable flow isolation and reliable operation under demanding pressure and temperature conditions. These valves feature a rotating butterfly disc and a metal-to-metal seating arrangement designed to provide robust sealing performance in applications where conventional soft seats may not be suitable. The wafer-style body is designed to fit between compatible pipeline flanges and is secured using the specified bolting arrangement, providing a compact and space-efficient installation. Depending on the valve design, the body, disc and metallic sealing surfaces can be selected to suit the process media and specified operating conditions. Manual, pneumatic or electric actuation options may be available to meet different operational and automation requirements.

Wafer Type Metal Seated Butterfly Valves are used in power generation plants, oil and gas facilities, refineries, petrochemical industries, steel manufacturing, chemical processing and other industrial pipeline systems. Depending on the specified materials, pressure rating and temperature limits, they can be selected for compatible liquids, gases, steam and certain high-temperature process media. Important selection factors include valve size, pressure class, operating temperature, flange compatibility, process media, body and disc materials, metal seat construction, allowable leakage rate and operating torque. Metal-seated designs can have different shut-off performance from resilient-seated valves, so the required leakage class should be confirmed during specification. For automated installations, actuator sizing and control system compatibility should also be considered. Selecting the appropriate valve configuration helps support dependable isolation, resistance to seat wear and consistent performance within the intended operating limits.
