How to Choose a Trunnion Mounted Ball Valve for Industrial Pipelines | Pressure Rating, Body Material, End Connection
Pressure ratings are typically selected between Class 150 and 2500; Conventional body material is WCB carbon steel, while CF8M stainless steel is specified for corrosive media; BW (Butt Weld) ends are recommended for high pressure, and RF (Raised Face) flanges for low pressure. During installation and mating, flange bolts must be tightened in a diagonal […]
What’s the Difference Between Soft Seat and Metal Seat Side Entry Ball Valves | Temperature Range, Sealing Performance, Wear Resistance
Soft-seated side-entry ball valves (such as PTFE) are suitable for temperatures below 200°C and can achieve Class VI zero leakage, but they have poor wear resistance. The pipeline must be purged before operation to prevent particles from scratching the valve seat. Metal-seated valves (such as those with tungsten carbide coatings) can withstand high temperatures up […]
