A butterfly valve is a quarter-turn rotary motion valve that is used to stop, regulate, and start the flow. Butterfly valves are a quick open type. A 90° rotation of the handle can completely close or open the butterfly valve.

Flange butterfly valve refers to a type of butterfly valve whose connection method is flange. This connection method is considered the most common one at present.

The butterfly plate of the flanged butterfly valve is installed in the diameter direction of the pipeline. The flanged butterfly valve is simple in structure, small in size and light in weight.

The opening and closing part of the flanged butterfly valve is a flange. The movement direction of the flange is perpendicular to the direction of the fluid. The flanged butterfly valve can only be fully opened and fully closed and cannot be adjusted or throttled.

Large flanged butterfly valves are usually equipped with gearbox type actuator, where the handwheel is connected to the stem via a gearbox. This will reduce the force but at the same time reduce the speed of the operation. The flanged butterfly valve should be installed in the open position.

Flanged butterfly valve is a kind of butterfly valve. It is the same as the flanged butterfly valve, which is another common connection method of butterfly valve and has a wide range of uses. The disc of flanged butterfly valves is a plate, swinging with valve shaft to turn on or off valves.

A flanged butterfly valve is usually cylindrical in shape, which is typically installed in a pipe system or as an inlet or outlet to some type of closed system.

Lug butterfly valves are throttling valves that turn in a quarter-turn rotary motion. Lug butterfly valves control the media flow in a system. The operators use these lug butterfly valves in different media and applications. When you operate a lug butterfly valve,

A lug butterfly valve is a kind of butterfly valve with a body that has “lugs” or hole protrusions around its circumference that provides passages for bolts.

The lug butterfly valve is connected between two pipe flanges with stud bolts. The structure of lug butterfly valve is simple, small in size and light in weight, which consists of only a few parts. Moreover, lug butterfly valve can be opened and closed quickly by rotating 90°.
