U-Type Flange Butterfly Valve

Waits valve U-Type Flange Butterfly Valve is durable, small in size, lightweight, and composed of only a few parts. In addition, it can be quickly opened and closed. When the flange butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance for the medium to flow through the valve body, so the pressure drop generated by the valve is very small, and it has better flow control characteristics. The sealing types of the U-Type Flange Butterfly Valve are elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded in the valve body or installed around the butterfly plate.

Feature

1. The butterfly valve has a simple structure, small volume, light weight, and is composed of only a few parts. In addition, simply rotate 90 ° to quickly open and close, making it easy to operate. At the same time, the valve has good fluid control characteristics.

2. The structure is simple and compact, and can be quickly opened/closed 90 °.

3. Extremely low operating torque, energy-saving.

4. The flow curve tends towards a straight line, indicating excellent regulation performance.

5. Wide range of material selection, suitable for various media.

Simply rotate 90 ° to quickly open and close, easy to operate. At the same time, the U-Type Flange Butterfly Valve has excellent fluid control characteristics.

The lifespan of metal sealed valves is usually longer than that of elastic sealed valves, but it is difficult to achieve complete sealing.

Comparison between U-Type Flange Butterfly Valve and Double Clamp Butterfly Valve

1. Material (similarity):

Valve body: gray cast iron; Ductile iron; Carbon steel.

Valve disc: ductile iron (nickel plated or nylon coated); 304/316 stainless steel; Aluminum bronze.

Valve stem: 410/416/304/316 stainless steel.

Valve seat: EPDM rubber; Nitrile rubber; teflon; Fluororubber; Heparen; Chloroprene rubber; Metal valve seat.

2. Pressure (similarity):

CLASS 125/150； PN10/16/25

3. Application scope:

The U-Type Flange Butterfly Valve is different from clamp or lug butterfly valves in that it uses flange connections and has a shorter end face length.

If butterfly valves need to be used for flow control, the most important thing is to choose the correct size and type of valve. The structural principle of butterfly valves is particularly suitable for making large-diameter valves. Butterfly valves are not only widely used in general industries such as petroleum, natural gas, chemical, and water treatment, but also in cooling water systems of thermal power plants.
