Product Description

The high-performance Double Offset Butterfly Valve, used in slightly higher-pressure systems, is offset from the centre line of the disc seat and body seal (offset one), and the centre line of the bore (offset two). This creates a cam action during operation to lift the seat out of the seal resulting in less friction than is created in the zero offset design and decreases its tendency to wear. Butterfly Valve is similar to that of a Ball Valve, which allows for quick shut off. Butterfly valves are generally favored because they cost less than other valve design, and are lighter weight so they need less support. The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open.FLange Double Offset Hard Seal Butterfly Valve
