Parameter

Hard-sealed butterfly valve, also called flap valve, is a regulating valve with a simple structure, and it can also

be used for on-off control of low-pressure pipeline media. The hard seal butterfly valve mainly cuts off and

throttles on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which

rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.

Hard-sealed butterfly valve is suitable for conveying various corrosive and non-corrosive fluid media in the

pipeline of producer, gas, steam, natural gas, city gas, cold and hot air, chemical smelting engineering and

power generation environmental protection system, used to regulate and cut off the medium . The flow.

Hard-sealed butterfly valves can be divided into manual hard-sealed butterfly valves, pneumatic hard-sealed

butterfly valves, and electric hard-sealed butterfly valves.

Advantage

The hard seal butterfly valve is an eccentric metal seal structure, the sealing form is metal to metal seal, metal

seal ring to metal seal can be exchanged, stainless steel plate and graphite composite plate seal ring to metal seal.

The drive form of hard seal butterfly valve is in addition to electric : Manual, worm gear drive, pneumatic, etc.

This type of valve should generally be installed horizontally in the pipeline.

The butterfly plate of the hard seal butterfly valve is installed in the diameter direction of the pipeline. In the

cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the

rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is in a fully open state.

Describe

The hard-sealed butterfly valve is a valve that realizes the opening or closing of the pipeline by the rotation of

the circular butterfly plate (sealing part) with the rotation of the valve shaft. It is mainly used as a cut-off valve,

and can also be designed to have the functions of cut-off and throttling adjustment. Hard-sealed butterfly valves

are increasingly used in low-pressure large and medium-caliber pipelines. The butterfly plate of the hard seal

butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly

valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°.

When the rotation reaches 90°, the valve is in a fully open state.
