The aluminum bronze C95800 globe valve is made of aluminum bronze material, which is a force-sealed valve, so when the valve is closed, pressure must be applied to the clapper to force the sealing surface to not leak. When the medium enters the valve from below the valve flap, the resistance to be overcome by the operating force is the friction force between the stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the stem The diameter should be large, otherwise the failure to bend the valve stem will occur.
The C95800 aluminum bronze has high strength and elasticity, high corrosion resistance in the atmosphere, fresh water, sea water and some acids, can be processed in hot and cold pressure, and can be welded by electric welding and gas welding.
