Vulcanized butterfly valve seat with Good elasticity and High reliability
Advntages of the vulcanized rubber valve seat:
Because of using of symmetrical channel structure, and rubber valve seat is made of high precision vulcanization, so whatever the direction of the medium, the seal can effectively cut off the flow from the pressure surface. SML rubber lined butterfly valve seats maintain superior sealing performance under high pressure.
The upper and lower valve shaft hole of the valve seat have double o - ring sealing ring structure, together with the up and down two sealing platform, ensuring that the butterfly valve shaft leakage won’t be happened during opening and closing. So whatever changes internally in the pipeline, the leakage won’t be happened.

Material Quick Selection Table:
| Material | Suitable Temp. | Characteristics |
| NBR |
-35℃~100℃ Instant -40℃~125℃ |
Nitrile rubber has good self-expanding properties, abrasion resistance and hydrocarbon-resistant properties. It can be used as a general material for water, vacuum, acid, salt, alkali, grease, oil, butter, hydraulic oil, glycol, etc. Can not be used in places such as acetone, ketone, nitrate, and fluorinated hydrocarbons. |
| EPDM |
-40℃~135℃ Instant -50℃~150℃ |
Ethylene-propylene rubber is a good general-purpose synthetic rubber that can be used in hot water systems, beverages, dairy products, ketones, alcohols, nitrates, and glycerin, but not in hydrocarbon-based oils, inorganics, or solvents.
|
| CR |
-35℃~100℃ Instant -40℃~125℃ |
Neoprene is used in media such as acids, oils, fats, butters and solvents and has good resistance to attack. |
| FKM |
-20℃~180℃
|
Fluororubber is a good hydrocarbon-resistant base oil, fluorinated hydrocarbon rubber for oily gas and other petroleum products. It is suitable for water, oil, air, acid and other media, but it can not be used for steam, hot water or thicker than 82 °C. Alkali system. |
| SR | -70℃~200℃ | Silicone rubber is resistant to high temperature, low temperature and stable chemical properties, and is widely used in industries such as strong acid, weak alkali and food. |
Special materials: carboxylated nitrile rubber, hydrogenated nitrile rubber, corrosion-resistant ethylene-propylene rubber, steam-resistant fluoroelastomer, chlorosulfonated polyethylene |
