Lug Type Butterfly Valves with Stainless Disc

Lug type vulcanised butterfly valves are chosen because they are cheaper than other valve designs and, being lighter, need less support. The disc sits in the middle of the pipe. A shaft passes through the disc to an actuator outside the valve. Turning the actuator rotates the disc parallel or perpendicular to the flow. Unlike a ball valve, the disc always stays in the flow, so it causes a pressure drop even when open. This product is manufactured in ductile iron with a stainless disc.
