C4 steel valves
Product performance and features
C4 steel ball valves and nitric acid is special ball valve, is designed and developed by the workers in Shanghai special valve of nitric acid medium, C4 steel with good corrosion resistance in nitric acid. C4 (nitric acid is special ball valve) of steel ball valve ball is floating, under the effect of medium pressure, the fitness ball produce certain displacement and compression at the outlet seal surface, guarantee the outlet seal. C4 (nitric acid is special ball valve) of steel ball valve features: 1, small flow resistance, ball valve is the smallest of all valve fluid resistance in the class a, even reducing ball valve, the fluid resistance is small. 2, C4 (nitric acid is special ball valve) of steel ball valve sealing performance is good. Ball valve seat (ring) generally use the elastic materials such as teflon, easy to guarantee the seal, and valve sealing force with medium pressure increases. 3, C4 (nitric acid is special ball valve) of steel ball valve stem seal and reliable. When the ball valve open/close the valve stem only rotate 90 ° movement, so the valve stem packing seal is not easy to be destroyed, and the valve stem pour sealing sealing force with medium pressure increases. 4, do 90 ° rotation of ball valve opening and closing, so easy to achieve automatic control and remote control, ball valve electric device can be configured, pneumatic equipment, hydraulic equipment.
