Spare parts
Sleeves of Pinch Valves
Sleeves are the top spare part of pinch valves. Corrosion resistance, abrasion resistance and anti-pressure ability of pinch valves all depends on ability of sleeves. This advantage makes pinch valves much easy to maintain.
We provide high strenth sleeves and different rubber materials are available.
Material of Sleeves
| Code | Name | Temperature | Feature |
|---|---|---|---|
| SBR | Styrene Butadiene Rubber | -40°C -100°C | Excellent abrasion resistance, anti-acid and alkali; bad resistance to oil and strong acid. |
| NR | Natural Rubber | -40°C - 80°C | Excellent abrasion resistance, good elasticity, anti-acid and alkali; bad resistance to oil and strong acid. |
| EPDM | Ethylene-Propylene-Diene Monomer | -40°C - +120°C | Good heat resistance, acid and alkali resistance, resistance to polar solvents; bad resistance to aliphatic hydrocarbon and aromatic hydrocarbons |
| NBR | Nitrile Rubber | -30°C - 100°C | Resistance to gasoline and aliphatic hydrocarbon; bad resistance to polar solvents, poor electrical insulation. |
