Product Description

The following are some of the most worthy points in the design of electric lug soft seated butterfly valve, which have been fully considered in terms of materials, structure and performance.

1. High elasticity of valve seat rubber: The rubber content of EPDM valve seat is 50%. We attach great importance to quality, and more than 10,000 opening and closing simulations ensure that the valve is leak-free.

Other relevant performance data can be referred to as follows: 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.

Moreover, our valve seat is designed with a wide edge, with a diameter of about 20mm, which has a wider contact surface with the pipeline flange than the narrow-edge valve seat, and has better sealing performance.

2. Because installing pins may cause corrosion and leakage, we use a pinless connection between the butterfly plate and the valve shaft, which makes the valve shaft easier to disassemble and facilitates the replacement of the valve seat.

3. The valve body is equipped with an anti-scattering device, which is safer.
