Wafer Type Butterfly Valve

Butterfly Valves are having wide range of applications in Process Industries, Water Treatment, Sewage Plants, Power, Petrochemicals, Steel Plants and allied industries in a very large quantity. All type of Butterfly Valves is available with control type lever, Manual Gear, Pneumatic and Electric Actuators. We offer Butterfly Valves in cryogenic type of design. Our butterfly valves are made up of high quality raw material and are designed to actually optimize its efficiency and they provide long lasting tightness and are highly reliable. They are very easy and fast to open.

A Butterfly Valve is a flow regulating disc valve. According to the BVAA, a Butterfly Valve is “a Valve in which the obturator rotates about an axis at right angles to the direction of flow and, in the open position flow passes around the obturator.” Butterfly Valves Manufacturer operate similar to Ball Valves in their 90-degree rotation and allow for quick shutoff.

Butterfly valves are recently have been in trends due to their very thin profile between flanges that makes the valves lighter in weight and create very small instant footprint. And this design of the valve makes its cost lower if compared with other valves. There are various types of butterfly valves and each of them has very unique design and features, for more information contact us right now.
