A procurement guide to the factors that determine the pressure rating of stainless steel ball valves. Learn about body material, wall thickness, seat design, and standards from Zhejiang Bolaisi Valve Co., Ltd.

Discover why ball valves are essential for water treatment and desalination plants. Technical analysis of corrosion resistance, high-cycle reliability, and sealing performance from Zhejiang Bolaisi Valve Co., Ltd.

Valves are the core control components of industrial fluid pipeline systems. They are widely used in water treatment, chemical industry, oil & gas, municipal engineering, metallurgy, power generation and other industries, performing functions such as medium shut-off, opening, flow regulation, backflow prevention and safety pressure relief. Incorrect valve selection may lead to leakage, equipment damage, system shutdown and even safety accidents. This paper systematically introduces the types of industrial valves, model interpretation, basic structure, material selection, actuators and frequently asked questions, providing scientific references for project selection, procurement and technical evaluation.Zhongjiang Bolaisi Valve Co., Ltd. has a professional sales and technical team, capable of providing you with accurate selection recommendations.
