GB welded gate valve

Overview：

The national standard welded gate valve is a type of gate valve that complies with Chinese national standards (GB/T, JB, etc.) and is connected to the pipeline by welding (butt welding or socket welding). Its core function is to cut off or connect pipeline media through the lifting and lowering of the gate, which has the characteristics of reliable sealing performance, low flow resistance, and high temperature and high pressure resistance. It is widely used in industrial fields such as power, metallurgy, chemical industry, and heating, especially suitable for working conditions that require welding installation and high medium cutting requirements (such as high-pressure steam pipelines and high-temperature oil pipelines).

Nominal diameter：10mm～2000mm and 1/2"～80".

Working pressure：0.25MPa～76.0MPa/150Lb～4500Lb/10K～320K.

Adopting standards：GB, DIN, API, ANSI, JIS, BS, etc.
