Industrial valves are an indispensable key component in various industrial pipeline systems, and the seal is one of the most important sealing components in the valve structure. To meet the special needs of different working conditions and application scenarios, customized non-standard rubber seals came into being.
This customized seal can be personalized designed and manufactured according to factors such as the structure of the valve, the working environment, and the characteristics of the medium to ensure the reliable sealing performance of the valve system.
Product Features
- Highly customized design: It can be customized according to the drawings, dimensions, materials, and other parameters provided by the customer.
- Flexible material selection: It covers a variety of rubber materials such as nitrile rubber (NBR), fluororubber (FKM), silicone rubber (VMQ), etc.
- Excellent high-temperature resistance: Some materials can withstand high-temperature conditions above 200°C.
- Strong chemical corrosion resistance: Suitable for various industrial media, such as oil, acid, alkali, solvents, etc.
- Stable and reliable mechanical properties: Excellent compression resistance, tear resistance, wear resistance, and other properties.
- Diversified size specifications: It can be designed specifically according to the valve structure and installation space.
Material selection
(1) Nitrile rubber (NBR)
Advantages: oil resistance, wear resistance, good mechanical strength. Suitable for most industrial occasions.
Disadvantages: poor heat resistance, generally ≤100℃. Not suitable for strong acid and strong alkali environments.
(2) Fluororubber (FKM)
Advantages: high-temperature resistance (≤200℃), excellent chemical resistance. Suitable for harsh working conditions.
Disadvantages: high hardness, poor elasticity. Relatively high price.
(3) Silicone rubber (VMQ)
Advantages: wide temperature range (-60℃~200℃), good weather resistance, and electrical insulation.
Disadvantages: mechanical strength and wear resistance are slightly worse than nitrile rubber.
Application Accessories
Customized non-standard rubber seals are widely used in various industrial valves, such as：
Pipeline valves such as gate valves, stop valves, ball valves, butterfly valves
Regulating valves such as regulating valves, safety valves, pressure reducing valves
One-way flow valves such as check valves and non-return valves
As the key sealing component of the valve, the seal ring forms a complete valve sealing system with the valve core, valve seat, valve cover, etc.
Applicable Media
Customized non-standard rubber seals can be widely used in various industrial media, such as:
Gases: air, nitrogen, oxygen, natural gas, etc.
Liquids: water, oils, acid and alkali solutions, alcohols, esters, etc.
Solid suspensions: mud, coal powder, mineral sand, etc.
According to the specific properties of the medium, choosing the right rubber material is the key.
FAQ
Q: How to choose the right rubber material?
A: It is necessary to comprehensively consider factors such as operating temperature, medium characteristics, and mechanical strength. Generally, nitrile rubber has the widest range of applications, while for more demanding environments, fluoro rubber or silicone rubber with excellent high-temperature resistance and chemical corrosion resistance can be selected.
Q: What information do I need to provide for custom non-standard seals?
A: Mainly, you need to provide parameters such as valve model, structural dimensions, installation space, operating temperature, and medium properties. We will design and manufacture them based on this information.
Q: How long is the delivery time for custom non-standard seals?
A: It depends on the specific order requirements, usually completed within 2-4 weeks. For urgent orders, we can also shorten the delivery cycle.
Q: What is the price of custom non-standard seals?
A: The price will vary depending on factors such as material, size, and quantity. We will provide a reasonable quotation based on your specific needs. Bulk orders usually enjoy more favorable prices.
In short, custom non-standard rubber seals can be designed according to different working conditions to help industrial valve systems achieve reliable sealing.
