Product Description

The soft seated wafer butterfly valve of Witts has the following designs during design and production, and has been improved in terms of performance:
1-High elastic valve seat rubber
The rubber content of the EPDM valve seat is 50%, and it has been tested for more than 10,000 times in simulation opening and closing tests without leakage.
Shore A hardness/degree 72 ±3,200% tensile stress/Mpa≥6, tensile strength Mpa≥15, elongation at break/%≥350, permanent deformation at break/%≦10, tear strength/KN.m-1≥35, compression permanent deformation (70℃*22h, compression rate 25%)/%≦20.
Compared with the narrow-edge valve seat, the wide-edge valve seat has a wider contact surface with the pipeline flange, with a diameter of about 20 mm, and better installation sealing performance.
2-The butterfly plate and the valve shaft are connected without pins, which can completely avoid leakage and corrosion caused by installing pins. The valve shaft is easy to disassemble, which is convenient for replacing the valve seat.
3-The valve body is equipped with an anti-flying device, which is better and safer to use in the pipeline.
