PNEUMATIC ACTUATOR OPERATED DOUBLE OFFSET DISC BUTTERFLY VALVE WAFER TYPE
“aline” Make Pneumatic Actuator Operated Double Offset Disc Butterfly Valve – Wafer Type Class 150 is specially engineered for high-performance flow control in demanding industrial applications. Featuring a double offset disc design, the valve minimizes seat friction during operation, resulting in longer seat life, lower operating torque, superior sealing performance, and reduced wear. It is actuated by a high-performance rack & pinion pneumatic actuator, providing fast, reliable, and maintenance-free quarter-turn operation.
The wafer-type body is designed for installation between ANSI Class 150 flanges, making it compact, lightweight, and easy to install. This valve is ideal for handling steam, hot water, compressed air, gases, oils, chemicals, and other industrial process media, where reliable shut-off and extended service life are essential.
