Series 120 Butterfly Valve

Designed for handling high volume solution flow, the Townley bi-directional Series 120 Butterfly Valve is an excellent choice for throttling or isolation service. This high-performance butterfly valve aligns to the center of the pipe perpendicular to the flow. Depending on the application the valve body can be lined with urethane or rubber for a bubble-tight seal.Series 120 butterfly valve
