Configuration Options:
|
Name of Parts |
Material |
Advantages/Disadvantages |
|
Valve Body |
Bronze |
Bronze has the characteristics of low melting point, high hardness, strong plasticity, wear resistance, corrosion resistance, bright color, etc. |
|
Cast iron |
The tensile strength, ductility and toughness of cast iron are lower than those of carbon steel. Lower price than bronze and stainless steel |
|
|
Carbon Steel |
Low strength, low hardness, good plasticity and good weldability. |
|
|
Stainless Steel |
High corrosion resistance makes it usable in harsh environments. It is fire and heat resistant, resists scaling and maintains strength at high temperatures. |
|
|
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. |
|
Aluminum Bronze |
It has high strength and good wear resistance. It is used for high-strength screws, nuts, copper sleeves, sealing rings, etc., and wear-resistant parts. The most prominent feature is its good wear resistance. |
|
|
Valve Seat |
NBR |
Applicable medium 0-80℃ oil class |
|
EPDM |
Suitable medium -20-120℃ water, steam, etc
|
|
|
PTFE |
Applicable to corrosive media below 200℃
|
|
|
Hard alloy |
Suitable for high temperature and high pressure environment |
|
|
Valve Stem |
Stainless Steel |
Key advantages include its high corrosion resistance, making it usable in harsh environments. It is fire and heat resistant, resists scaling and maintains strength at high temperatures. |
|
Handle |
Cast Iron |
Cost less than bronze |

Result |
|
Reduce body thickness to reduce costs |
At high temperature and high pressure or during operation, the thin wall is easy to rupture or leak the valve, causing a safety hazard. |
Ensure that the thickness of the valve body meets the standard requirements, and there is no fraudulent behavior |
Use with confidence, meet user needs, and the product has a long service life |
|
To reduce costs, refurbish old valves to act as new valves and re-sell |
Refurbished valves are easy to cause shell cracking and leakage, and in severe cases, oil and gas pipelines will explode. |
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. |
|
Valve seat is made of waste rubber |
Not durable and waste of resources, once the valve seat is worn and damaged, the entire valve is considered waste |
The rubber valve seat is made of a new type of super wear-resistant rubber, and can be reused |
The rubber material is super wear-resistant and can be reused, and the valve can be used for a longer time |
|
The valve seat, valve stem, and valve disc are all fixed configurations, which cannot be disassembled and assembled individually, and cannot be replaced with individual parts. |
If a part is damaged, it can only be replaced as a whole, wasting resources and increasing costs |
Seat, stem and disc are standard parts |
Replacing accessories is simple and easy, saving time and effort. Not only reduce costs, but also save resources for the country |
