Complete guide to installing valve handwheels, wrenches, locking devices, and position indicators per API 6D / ISO 14313 standards. Learn key requirements for operating force limits, dimensions, torqu

The structure of a gate valve body is determined by its connection methods to the pipeline and valve bonnet. Based on manufacturing techniques, gate valve bodies can be classified into several types:

The design of a gate valve body is determined by its connections to the pipeline and the valve bonnet. Common manufacturing methods include casting, forging, forged-welding, cast-welding, and pipe pla

Welded flange steel gate valves are suitable for cutting off or connecting media on pipelines in various working conditions such as petroleum, chemical, and thermal power plants with nominal pressures

The structure of a gate valve body is determined by its connections to the pipeline and the valve cover. In terms of manufacturing methods, the body can be produced by casting, forging, forged-welding

Knife-shaped slurry gate valve is made into two types of non-rising stem and rising stem according to different diameters (non-rising stem DN50~900mm and rising stem DN50~900mm). Full-circular DC chan

Knife gate valves excel in harsh industries like pulp/paper and chemicals. Their full-bore, clog-proof design and unique U-seal ensure reliable flow control and tight shut-off with minimal maintenance

The general category mainly based on JB/T2203-1999 "Structural Length of Gate Valves". At present, most domestic safety valve manufacturers design and produce according to this standard. Working princ
