In this article,  Bundor Valve will introduce to you what material the manual butterfly valve is.
Q: What material is the manual butterfly valve? What materials do manual butterfly valves have?
Bundor Valve: Manual butterfly valve is a very common type of butterfly valve, and it has a wide range of uses. Whether it is water, air, oil, dust, etc., manual butterfly valves are used. Manual butterfly valves of different materials can be used in different working conditions.

The main components of manual butterfly valve are valve body, valve seat, butterfly plate, valve shaft and drive.

First of all, the material of the valve body. The valve body materials of manual butterfly valves are gray cast iron, ductile iron, cast steel, stainless steel, etc. The performance of the material is stainless steel> cast steel> ductile iron> gray cast iron.

However, if it is in a low pressure environment, The performance of ductile iron is comparable to that of cast steel, and the cost of using ductile iron is lower.

The second is the seat material. According to the seat material, manual butterfly valves are divided into two types: soft seal and hard seal. The seat materials of the soft-sealed manual butterfly valve are mainly rubber and fluoroplastics. The rubber seat can be used in weak acid and weak alkaline media such as water, steam, oil, etc., with good sealing performance; the fluoroplastic seat is used for strong corrosiveness. Medium.

Hard-sealed manual butterfly valves are mostly made of alloy steel, stainless steel, etc., which are suitable for high temperature and high pressure environments, but have poor sealing performance.

Then comes the butterfly plate material. The butterfly plate material of the manual butterfly valve is mainly ductile iron and stainless steel. Sometimes in order to adapt to the more complicated medium environment, the butterfly plate needs to be coated or coated with tetrafluoroethylene material.

Next is the valve shaft material, which is basically stainless steel.

Finally, the driving material of the manual butterfly valve. There are two main operating modes for manual operation, the handle and the worm gear. The handle materials are mainly cast iron, carbon steel, stainless steel, aluminum alloy, etc.; the worm gear head is mostly made of cast iron.
