Butterfly Valve

A butterfly valve is a valve that isolates or regulates the flow of a fluid.

The closing mechanism is a disk that rotates. Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. It is often said that butterfly valves can be used to regulate the flow.

Quality Control

A valve can be described as a mechanism that controls the passage of liquids through a pipe. Research states that valves being manufactured in China are amongst the top valve competitors in the valve industry.

Why Do I Need Wear Parts?

“Wear” is the last thing any business wants to experience with their machines. Apart from its unpleasant physicality, it could also be a sign that means your parts and/or components are about to break. You need wear parts to help prevent or prolong the wearing out of these parts and components – and that could be any type of wear parts such as pipes, liners, plates, etc.

What Kinds of Wear Plates Do You Offer?

Here at Sunny Steel, we put emphasis to the primary kinds and types of wear pipes and fittings – they include:
  • Ceramic Liner pipes and fittings
  • Ceramic tile lined pipes and fittings
  • Ceramic sleeve lined pipes and fittings
  • Cast basalt lined pipes and fittings
All of them have their particular uses, but these cover almost all the materials companies need to work on.

Merits and Salient Features

  • Extremely High Resistant to Abrasion, Erosion and Corrosion.
  • Resistant to most of the Chemicals, Alkalis and Acids.
  • Very Long life
  • Less Down time and Maintenance Cost.

What is double eccentric butterfly valve?

The double eccentric butterfly valve is also called high-performance butterfly valve, which is mainly used for drainage of water works, power plants, steel smelting, chemical industry, water source spring engineering, environmental facilities construction and other systems, especially for waterway pipeline, as regulation and closure equipment. Compared with the center line butterfly valve, the double eccentric butterfly valve has higher pressure resistance, longer service life and better stability.

Working principle: double eccentric butterfly valve is further improved on the basis of single eccentric butterfly valve. The structural feature is that the axis of the valve stem deviates from the center of the butterfly plate and the body. The effect of double eccentricity enables the butterfly plate to break away from the valve seat immediately after the valve is opened, greatly eliminates the unnecessary over extrusion and scratch phenomenon between the butterfly plate and the valve seat, reduces the opening resistance distance, reduces the wear and improves the service life of the valve seat. At the same time, the double eccentric butterfly valve can also use metal seat, which improves the application of butterfly valve in high temperature field.

Structural characteristics:

  1. It is reasonable in design, compact in structure, easy to install and dismantle, and easy to maintain.
  2. Eccentric structure is adopted to reduce the friction of sealing ring and prolong the service life of valve.
  3. Completely sealed, leakage zero. It can be used in ultra high vacuum condition
  4. Replace the sealing ring, butterfly plate, rotating shaft and other materials of valve plate, which can be used in various media and different temperatures.
