PRODUCT DESCRIPTION:
A butterfly valve is a mechanism that regulates the flow of materials within large pipe diameters by the quarter-turn rotation of a disc.
A rod feeds through the center of a disc and this rod is connected to an actuator that controls the motion of the disc. The disc position is either parallel or perpendicular to the flow media. A butterfly valve differs from other valves because the disc is always in the flow causing a pressure change for any position of the valve
Sound systems reply on dependable valves. Our butterfly control valve selection is made up of disc valves perfectly sized for various applications and made in precise accordance with industry standards.
