The role of the gate valve in the pipeline system and its material application differences

The core difference between cast steel gate valve and cast iron gate valve lies in the material characteristics and pressure capacity. Cast steel gate valve with high strength, corrosion resistance, petrochemical, natural gas and other high-pressure (> 1.6MPa), high temperature or corrosive media pipeline of choice. Cast iron gate valve is simple structure, low cost, widely used in water supply and drainage, municipal engineering and other low pressure (≤ 1.6MPa) system. Selection should be based on the working pressure, temperature and media characteristics, to ensure the safe and stable operation of the pipeline.
