Lipin Butterfly Valves:

Ultimate control solves all your problems
Butterfly valve is usually used in low-pressure pipeline opening and closing, butterfly valve opening and closing parts for the butterfly plate (circular), driven by 90° rotation of the valve stem to achieve the function of opening and closing, the diameter size can be customized according to customer needs, we currently do the maximum diameter of DN5000(250 "). When the butterfly plate of the butterfly valve is fully open at 90°, the thickness of the butterfly valve is the only resistance when the fluid passes through the valve, so the resistance and pressure are relatively small. The defect is that it is not suitable for media through high pressure. The structure of butterfly valve is characterized by small diameter, thin thickness and light weight. Compared with other valve price advantages, can be divided into concentric butterfly valve, eccentric butterfly valve, double convection butterfly valve, high performance butterfly valve.

Industrial Butterfly Valves

In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis with a rotation angle between 0° and 90°. When rotated to 90°, the valve is fully open. At this time, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated through the valve is very small, so it has good flow control characteristics.

A common application of butterfly valves is water conservancy projects. It is also used in pipelines transporting various corrosive and non-corrosive fluid media in engineering systems such as generators, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting, power generation and environmental protection, and is suitable for flow regulation. Since the pressure loss of butterfly valves in the pipeline is relatively large, about three times that of gate valves, when selecting butterfly valves, the impact of pressure loss on the pipeline system should be fully considered.

Butterfly valve operating principles:
  • 1.Rotation 90° movement：
    The valve stem drives the butterfly plate to rotate to achieve opening and closing.
  • 2.Straight through：
    When the butterfly plate rotates to 90°, the resistance is only the thickness of the valve disc, and the flow resistance is relatively small.

Key Components of Butterfly Valve

The butterfly valve consists of several key components: valve body, valve disc（butterfly plate）, valve stem and valve seat. Every component is an important guarantee for the valve during operation.
  • Valve body
    The butterfly valve body commonly has lug and butterfly plate types. The bolt holes on the lug match the bolt holes on the pipe flange.
  • Valve stem
    Different from other valves, the butterfly valve drives the valve disc through the rotation of the valve stem and does not require lifting movement.
  • Valve disc
    As the opening and closing part of the butterfly valve, the valve disc can be rotated 90° to achieve full opening and plays the most important role in opening and closing.
  • Valve seat
    the sealing component of the valve, which can be a fireproof valve seat, a flexible valve seat or a metal valve seat to prevent medium leakage

Choosing Butterfly Valves

  • Advantages of industrial Butterfly valves:

    The opening and closing torque is small and convenient, the structure is compact, and it is suitable for large diameters.

    Better sealing in low pressure environment

    Can pass through media containing particulate matter without clogging

    Simple structure, easy to install and flexible to operate

    Various types of butterfly valves can be customized to achieve different usages

    High efficiency in regulating water volume and water level

  • Disadvantages of Industrial Butterfly Valves:

    Due to limitations of structure and sealing materials, it is not suitable for use in high temperature and high pressure pipelines.

    The sealing performance is worse than that of ball valves and globe valves, and the sealing requirements are not high.

    Compared with the ball valve with 0 flow resistance, there is a valve disc as resistance

    The flow adjustment range is not large

Common types of butterfly valve classification

do you want one?
Lipin produces a variety of different types of valves, butterfly valve is also one of our main production valve, butterfly valve is suitable for a variety of different working conditions, usually used for the flow of water medium, suitable for manufacturing into a large caliber butterfly valve, the following are several types of butterfly valve classification.
Butterfly Valve Type By Valve Connection Design
Depending on the design of the pipeline, we also provide a variety of connection methods and connection design standards to ensure that our valves can fit perfectly.
Butterfly Valve Type By Disc Design
Butterfly valves can be distinguished from the direction of the butterfly plate, and we divide them into three different types
