This electric flange type soft sealing butterfly valve is consisted of valve body,valve disc and soft sealed valve seat.Capable of cutting off the fluid, the mid-line butterfly valve is generally used for the medium like water,oil,gas and other corrosive product with the temperature less than 80ºC.Benefits- The valve body of the wafer butterfly valve is symmetric by the center line. So the installation of the soft sealing butterfly valve is easy and convenient.
- Manufactured with PTFE,NBR or other materials, the valve seat will not fall off. Besides convenient replacement,the manual wafer rubber lined butterfly valve has good leak-proof and strength resistance performance.
- With integrated structure,the valve stem of the rubber lined butterfly valve has higher strength.The elaborate processing can prevent the medium from leaking effectively.
- The precise valve disc is polished .Well matched with the valve seat,the valve disc has outstanding sealing performance.
