BUTTERFLY VALVES

MstnLand provides high performance butterfly valve products, including Hard seal and soft seal butterfly valve, triple offset/double offset/centric butterfly valve, Lug type /Wafer type/Hoop type/Flanged ended butterfly valve and three-way butterfly valve. Especially our Bi-directional seal butterfly valve can be tested at 1.1 times design pressure with zero leakage at both directions.

Butterfly valve is a kind of valve that takes a disc as closing part (butterfly board) which rotates around the valve axis to achieve opening and closing. The valve is mainly used for cut-off and throttling on pipeline. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. The flow of medium may be controlled by changing deflection angle of butterfly board.

Butterfly Valves Overview

What is a butterfly valve？

Butterfly valve, also known as flap valve, is a regulating valve with simple structure. The butterfly valve uses a disc type hoist to rotate back and forth by about 90 ° to open, close or adjust the medium flow. Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals and radioactive media.

Butterfly valve is not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving torque, simple and rapid in operation, but also has good flow regulation function and closing sealing characteristics. It is one of the fastest-growing valve varieties in recent decades.

Why we call it a butterfly valve?

Some valves are named for their shapes, such as ball valves, globe valves, needle valves, etc. Other valves are named for their rotating forms and functions gate valves, plug valves, pinch valves, slide valves, etc. Butterfly valves are also named for their rotating form.
