Product overview of ITALY ball valve
one of the products in the pneumatic ball valve series. Also known as pneumatic ultra-thin ball valve. It is a new generation of ultra-short flange distance ball valve developed by our company through introducing Italian technology for domestic design. V-shaped and O-shaped. Pneumatic pair Clip Ball valve with compact structure, small size, light weight, easy installation and other characteristics. Pneumatic pair Clip Ball valve is a new type of ultra-short flange distance ball valve, which is developed by absorbing Italian technology and domestic design.Pneumatic ultra-thin ball valve It adopts direct connection to implement the mechanism connection. It has the advantages of compact structure, small size, light weight, small frictional resistance, small backlash, stable and reliable operation, etc. Pneumatic ultra-thin ball valve can be widely used in petroleum, chemical, metallurgy, In fields such as power stations and light industries, automatic adjustment or cut-off control of oil, water, gas, and pulp or fibrous fluids.
