What is a Forged Gate Valve?

Forged steel gate valve is a kind of gate valve whose parts are made of forging material. The gate of the forged steel gate valve moves along the vertical direction of the center line of the passage. It is mainly used for shut-off functions in the pipeline. The forged steel gate valve is a widely used valve. It is generally used for the shut-off device with a size≤2”.

ZECO is a forging gate valve manufacturer. Forged gate valves are suitable for various industrial conditions, and can be used for the installation of ground pipelines and underground pipelines. Because forged valves have better corrosion resistance than cast ones, they can avoid the high cost of frequent replacement caused by corrosion. According to the connection mode, forged gate valve can be divided into four types: threaded connection, socket welding connection, butt welding connection, and flange connection. The threaded connection is one of them, which can be mainly used for internal thread connections or external thread connections, and pipeline thread connections. The threaded connection is usually used for the middle and low-pressure pipelines; Socket welded connections are suitable for high-pressure pipelines, usually found in small diameter forged gate valves less than 2 inch; Butt welding is also suitable for high-pressure pipelines, but it usually occurs in large diameter forged gate valves of more than 2 inch; Flange connection can be divided into integral flange and welding flange two kinds, according to the specific working conditions of users to choose; Forging gate valve is mainly used for cutting off, so it can be applied to the pipeline with bidirectional flow of the medium.
