Butterfly Valve

A Butterfly valve is a quarter-turn rotational motion disc valve, which is used to stop, regulate, and start the flow. Butterfly valve consists of a circular metal disc or plate built with a stem through the middle or attached offset. A metal disc or plate in the body of the valve is positioned perpendicular to the flow in the closed position and rotated 90° aligning with the flow in the fully opened position.

This type of valves has gained popularity over the years due to their thin profile, lightweight design that requires considerably less space, as compared to other valves. There are used in all type of industries application even in High-pressure and temperature services

Butterfly valves can be operated manually, electronically or pneumatically. Large Butterfly valves are usually equipped with gearbox type actuator, where the hand-wheel by gears is connected to the stem.

Butterfly valves are easy and fast to open. A 90° rotation of the handle provides a complete closure or opening of the valve. Large Butterfly valves are usually equipped with a so-called gearbox, where the hand wheel by gears is connected to the stem. This simplifies the operation of the valve, but at the expense of speed.
