Anti rust ability of ball valve has passed ASTMB-117 and CNS8886 salt spray test
All ball valves are heat treated and stress relieved, 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 ball valve is greater than 0.8 times of the height from the downforce to the rated deflection, and the downforce of the ball valve pressure is greater than 50% of the rated deflection
Ball valve deflection 25mm~125mm Shanghai Dongfeng Environmental Protection Supply Zhongzhen brand metal pneumatic butterfly valve fan pneumatic butterfly valve low frequency damping pneumatic butterfly valve pneumatic butterfly valve pneumatic butterfly valve advantages: 1. The shape of the pneumatic 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 pneumatic butterfly valve
