PNEUMATIC ACTUATOR OPERATED CENTRIC DISC BUTTERFLY VALVE WAFER TYPE
“aline” Make Pneumatic Actuator Operated Centric Disc Butterfly Valve – Wafer Type Class 150 is designed for reliable and efficient on/off flow control in a wide range of industrial applications. The valve features a concentric disc design with a resilient seat, ensuring bubble-tight shut-off, low operating torque, and long service life. It is integrated with a high-performance rack & pinion pneumatic actuator that provides fast, smooth, and maintenance-friendly operation.
The wafer-type body is compact, lightweight, and suitable for installation between ANSI 150# flanges, making it an ideal choice for pipelines where space and weight are important considerations. It is widely used in Water Treatment, Chemical Processing, Food & Beverage, Pharmaceutical, HVAC, Paper, Textile, Power Plants, Steel, Cement, Oil & Gas, and General Process Industries. Butterfly valves are commonly used for quick quarter-turn isolation and flow control.
