The EPDM butterfly valve design is novel and reasonable, the structure is unique, the weight is light, and the opening and closing is rapid.
The centre-pivoted butterfly valve have small operating torque, convenient operation, labor-saving and smart.It can be installed and maintained at any position.
The sealing material is resistant to aging, corrosion, and has a long service life.
The soft seated wafer butterfly valve seal can be replaced, and the sealing performance is reliable to achieve two-way sealing with zero leakage.
