Gate Valve 2 inch gate valve can also be called 50mm gate valve or dn50 gate valve. Different countries have different expressions, but the size is the same. With its advantages of small size, small flow resistance, light weight, easy installation, and easy disassembly, the 2 inch gate valve completely solves the difficult problems of other types of valves such as large flow resistance, heavy weight, difficult installation, and large footprint. Applicable media: gold ore powder, tailings, pulp, wood pulp, fiber, dust, chemical treatment sewage, sedimentation tank, ore sand, slag, coal slime, asphalt, silo outlet, fruit, grain, cement slurry, slaughterhouse wastewater Wait. Application 1. This product is mainly used as an opener on gas and liquid medium pipelines to connect or cut off the medium flow, and is not suitable for adjusting the medium flow. It has the advantages of small flow resistance and labor-saving opening and closing. 2. Scope of application: petroleum, petrochemical, natural gas and other industries. 2 inch Gate valves are divided into flange gate valves, threaded gate valves and wafer gate valves according to the connection method. Flanged gate valve: Flange connection is that the valve body has flanges at both ends, corresponding to the flanges on the pipeline, and is installed in the pipeline by bolting the flanges. Threaded gate valve: It is a simple connection method and is often used for small valves. The valve body is processed according to each thread standard, and there are two kinds of internal thread and external thread. Corresponds to the thread on the pipe. Wafer gate valve: The valve is installed between two flanges. There are usually positioning holes on the valve body to facilitate installation and positioning. The valve and the two pipes are directly clamped together with bolts. The gate valve connected to the wafer is a knife gate valve. The materials of gate valves The materials of gate valves are: stainless steel, forged steel, cast steel, cast iron, copper (also divided into bronze, brass) and so on. Stainless steel gate valve material is divided into 304 stainless steel gate valve, 316 stainless steel gate valve and so on. Forged steel gate valve: Forged steel gate valve is suitable for small diameter pipelines of Class150 ~ 2500, working temperature -29 ~ 425 鈩?(carbon steel) or -29 ~ 500 鈩?(stainless steel), used to cut off or connect the medium in the pipeline . Cast steel gate valve: all gate valves that are cast into castings with metal steel materials are collectively referred to as cast steel gate valves. Cast iron gate valve: Cast iron gate valve is further divided into gray cast iron gate valve and ductile iron gate valve, which are mostly used in water system pipelines.Gate Valve website:http://www.ka-valve.com/gate-valve/
