Why choosing 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.
