Pipes and Fittings

Butterfly valves are throttling valves used to control flow through a circular disc by turning the valve’s main axis at ninety degree or right angles towards the direction of flow in the pipe. These valves use an inflatable seat to seal with air pressure, thus requiring less torque and a smaller actuator, resulting in lower overall valve cost.

The demand for actuated butterfly valves is growing because actuated butterfly valves can provide: precise, repeatable control for industrial process, complex automatic sequencing for process control. These important industrial fittings control the flow of gas or liquid by means of a disk, which turns on a diametrical axis inside a pipe or by two semicircular plates hinged on a common spindle, which permits flow in a single direction. These compactly designed valves offer a rotary system movement of less than 90 degree. The valves are manufactured in materials including stainless steel, plastic, ceramic and PVC.
