Advantages/Disadvantages |
|
Valve Body |
Grey cast iron |
The most common material in butterfly valves, mainly used in water systems, is easily corroded, has a short service life and is cheap. |
|
Ductile cast iron
|
The performance of the butterfly valve is comparable to that of carbon steel. It is generally used in water system pipes, and it is also a very widely used material in water systems at present. |
|
|
Carbon steel |
It can also be used in water systems, but it is not used much. Carbon steel butterfly valves have high temperature and pressure resistance. Generally, hard-sealed butterfly valves are mostly made of carbon steel. |
|
|
Stainless Steel
|
It has good anti-corrosion and anti-corrosion properties, and is also mostly used in pipelines that need anti-corrosion and anti-rust, and the cost is relatively high. |
|
|
Valve Disc |
Stainless Steel
|
Stainless steel has a strong ability to resist tension, wear and corrosion. Stainless steel is much stronger than copper in material. Stainless steel will not produce corrosion, pitting, rust or wear and high temperature resistance. |
|
Bronze |
Bronze has excellent low temperature resistance, good corrosion resistance, wear resistance, casting and excellent mechanical properties |
|
|
Valve Seat |
EPDM |
Suitable medium -20-120℃ water, steam, etc |
|
NBR
|
Applicable medium 0-80℃ oil class |
|
|
PTFE
|
Applicable to corrosive media below 200℃ |
|
|
Hard alloy |
Suitable for high temperature and high pressure environment |
|
|
Hand Wheel |
Cast Iron |
Cost less than bronze and cast steel |

Consequence |
|
Jerry-build, the wall thickness of the valve body is not processed according to the standard |
Uneven thickness, and material, the valve body is easy to be damaged, and the service life is short. |
Strictly in accordance with the standard processing, uniform thickness, and material |
Use with confidence, meet user needs, and the product has a long service life |
|
Use iron, carbon steel to manufacture valves and repair scrap valves as shoddy valve products. |
Such products generally have large errors in hardness and accuracy. It is easy to cause the shell to crack, and the phenomenon of running, running, dripping and leaking occurs, and in severe cases, it will cause the explosion of the oil and gas pipelines. |
According to customer requirements to manufacture new valves, never shoddy. |
Meet the hardness and precision requirements of standard valves, Ensure the quality of the valve and ensure the normal operation of the equipment. |
|
The manufacturer considers the cost and purchases unqualified standard bolts |
Leaving hidden dangers on the valve can easily lead to accidents. |
According to customer requirements, use standard bolts. |
Use it with confidence, reduce safety hazards and reduce the accident rate. |
