Butterfly Valve Seat
Seat materialEPDM, NBR, PTFE, VITON, SILICONE
| Material Name | Temperature Range | Media Application | Main Properties | Typical Colour |
|---|---|---|---|---|
| EPDM | -10℃ to 110℃, High temperature resistance 130℃ | Steam, air, water, warm air, coolant | General EPDM rubber: is a good general-service synthetic rubber. It has good temperature resistance, corrosion resistance and aging resistance. | Black |
| NBR | -10℃ to 80℃ | Hydraulic oil, gasoline, water, silicon grease, silicone oil, diester lubricating oil, glycol system | Buna-NBR:(Nitrile Butadiene Rubber) has good tensile strength. Excellent oil resistance, air tightness and resistance to abrasion. It is also resistant to hydrocarbon products. | Black |
| PTFE(Teflon)/ RPTFE | -20℃ to 150℃ -20℃ to 180℃ | Strong acid and alkali and other corrosive media | PTFE has good chemical performance stability and surface will be not sticky. It has good chemical corrosion resistance, oxidation resistance, weathering resistance. R means Reinforced, which uses glass fiber to reinforce PTFE. | White |
| VITON | -20℃ to 180℃ | Mineral oil, silicone oil and silicone ester, gasoline, Strong acid | Viton is a fluorinated hydrocarbon elastomer with excellent resistance to most hydrocarbon oils and gases and other petroleum-based products. | Black |
| SILICONE | -10℃ to 150℃ | Food, high temperature medium | Silicone Rubber has good resistance to high temperature and low temperature and its chemical is stable, good sealing performance, at the high temperature, no deformation, no harmful substances, good tensile resistance. | Slightly white |
