Custom Cut Off ball Valve Manufacturers

Zhejiang Lasen Intelligent Equipment Co., Ltd. Is Custom Cut Off O-ball, V-ball, Three-way Ball Valve Suppliers Online. It Offers Cut Off Va

The BR.W8 series ball valve has excellent cutting performance. When fully open, its flow path and pipeline inner diameter are basically the same, and the fluid pressure loss is minimal. Therefore, it is suitable for cutting and control of various liquids, gases, slurry and other fluids. Ball valves can be divided into O-ball, V-ball, three-way ball valves, and eccentric rotary valves to meet different working conditions and on-site requirements. The O ball has a simple structure, small volume, smooth flow channel, low flow resistance, and high flow capacity, without any flow direction requirements for the medium. The V ball can add adjustment functions on the O ball and is more suitable for medium with high viscosity. Three way ball valves and eccentric rotary valves can play their unique roles under specific working conditions, such as the diversion and confluence of three way ball valves, and the cutoff and adjustment function of eccentric rotary valves on particulate media. The conventional materials for ball valves are carbon steel and stainless steel, and special alloy materials such as Ti, Hastelloy C, duplex steel, etc. can also be selected according to on-site conditions. Metal lining F46 or PFA can also be added to cope with corrosive media. The maximum nominal pressure of this series can reach 2500Lb, and the maximum diameter can reach DN500.
