Anti rust ability of butterfly valve passed ASTMB-117 and CNS8886 salt spray test
All butterfly valves are subject to heat treatment and stress relief treatment, with good fatigue resistance
The body is made of carbon steel, and the surface is treated with dactyl rust
Bottom anti slip and reverse bolt design
Simple installation, with height pad to fix the use height
The diameter of the butterfly valve is greater than 0.8 times the height from the downforce to the rated deflection, and the downforce of the butterfly valve is greater than 50% of the rated deflection
Butterfly valve deflection 25mm~125mm Shanghai Dongfeng Environmental Protection Supply Zhongzhen brand metal electric butterfly valve fan electric butterfly valve low-frequency damping electric butterfly valve electric butterfly valve electric butterfly valve advantages: 1. The shape of the electric butterfly valve can be arbitrarily selected, so that the stiffness in the upper, lower, left, right, front and back directions can be obtained through the reasonable design of valve components, which can greatly simplify the structure of the electric butterfly valve
