Vcore Valve supplies rubber-lined valves for corrosive, abrasive and slurry pipeline applications. Rubber lining helps protect the valve body from chemical attack, erosion and wear when handling wastewater, seawater, acids, alkalis, slurry and other aggressive media.
Our rubber-lined valve options include rubber-lined butterfly valves, rubber-lined check valves, rubber-lined gate valves and customized lined valve solutions for chemical processing, water treatment, mining, slurry handling and industrial fluid control.
Valve selection can be based on working media, concentration, temperature, pressure, flow rate, particle content, connection standard and operation method. Send us your application conditions, and our team can help recommend a suitable rubber-lined valve solution.
Different rubber lining materials are suitable for different media, temperatures and operating conditions. Selecting the wrong lining material may reduce sealing performance, shorten valve service life or increase maintenance cost.
For rubber-lined valves, common lining options include EPDM, NBR, natural rubber and other elastomer materials depending on the working media. For stronger chemical corrosion, PTFE-lined or PFA-lined valves may be more suitable than rubber-lined valves.
| Lining Material | Suitable Conditions | Typical Applications |
|---|---|---|
| EPDM | Water, seawater, mild acids, alkalis and wastewater service | Water treatment, chemical wastewater, desalination and utility pipelines |
| NBR | Oil-containing water, selected hydrocarbons and general industrial media | Oily wastewater, industrial process water and pump discharge lines |
| Natural Rubber | Abrasive slurry and particle-containing media | Mining slurry, tailings, mineral processing and abrasive wastewater |
| Butyl / Special Rubber | Selected chemical media depending on compatibility | Chemical processing, acid/alkali transfer and corrosive process lines |
| PTFE / PFA Lining | Strong acids, solvents and highly corrosive chemical media | Chemical plants, corrosive fluid transfer and high-purity chemical systems |
Vcore Valve supports customized rubber-lined valve selection for corrosive, abrasive and slurry applications. Our team can help review your working media, concentration, temperature, pressure, particle content, flow conditions and installation requirements before recommending a suitable valve type and lining material.
Available customization options may include valve type selection, rubber lining material selection, flange standard confirmation, actuator matching, body material selection, pressure testing and project documentation support.
| Advantage | Why It Matters | Application Value |
|---|---|---|
| Corrosion Protection | Rubber lining isolates the valve body from corrosive media | Helps extend valve service life in wastewater, seawater and chemical pipelines |
| Abrasion Resistance | Suitable lining materials can resist particle wear | Useful for slurry, mining, tailings and abrasive wastewater service |
| Cost-Effective Body Protection | The valve body can be protected without using expensive alloy materials for every part | Helps reduce total procurement and maintenance cost |
| Flexible Valve Types | Butterfly, check, gate and customized lined valve options are available | Easier to match different pipeline functions |
| Project-Based Selection | Lining material, valve type, connection and operation method can be selected according to working conditions | Reduces selection mistakes before quotation |
Rubber-lined valves are mainly used where the valve body needs protection from corrosion, erosion or abrasive particles. They are especially suitable for water treatment, chemical wastewater, mining slurry, seawater systems and industrial process pipelines.
| Application | Suitable Valve Types | Key Requirements |
|---|---|---|
| Chemical Wastewater | Rubber-lined butterfly valves, check valves, gate valves | Corrosion resistance, reliable shut-off, lining compatibility |
| Water Treatment | Rubber-lined butterfly valves, rubber-lined check valves | Low maintenance, corrosion protection, easy installation |
| Mining and Slurry | Rubber-lined gate valves, slurry valves, check valves | Abrasion resistance, anti-wear lining, durable sealing |
| Seawater and Desalination | Rubber-lined butterfly valves, rubber-lined check valves | Saltwater corrosion protection, stable sealing, flange compatibility |
| Acid and Alkali Transfer | Rubber-lined or PTFE-lined valves depending on media | Chemical compatibility, lining selection, leakage prevention |
| Pump Discharge Lines | Rubber-lined check valves, butterfly valves | Backflow prevention, pressure resistance, erosion protection |
1. What are rubber-lined valves used for?
Rubber-lined valves are used for corrosive, abrasive and slurry media where the valve body needs protection from chemical attack, erosion or wear.
2. What valve types can be supplied with rubber lining?
Common rubber-lined valve types include butterfly valves, check valves, gate valves and customized lined valve solutions for industrial pipeline systems.
3. How do I choose the right rubber lining material?
Lining material selection depends on the working media, concentration, temperature, pressure, particle content and chemical compatibility. EPDM, NBR, natural rubber and special rubber materials may be selected for different applications.
4. Are rubber-lined valves suitable for strong acids and solvents?
It depends on the media concentration and temperature. For strong acids, solvents or highly corrosive chemical media, PTFE-lined or PFA-lined valves may be more suitable than rubber-lined valves.
5. Can rubber-lined valves be used for slurry service?
Yes. Rubber-lined valves can be suitable for slurry and abrasive media when the lining material, valve structure and flow conditions are correctly selected.
6. What information should I provide for quotation?
Please provide valve type, size, pressure rating, connection standard, working media, concentration, temperature, flow conditions, quantity and operation method.
