A forged steel gate valve is a type of gate valve whose parts are made of forged material. The slider of the forged steel slider moves along the vertical direction of the center line of the passage. It is mainly used for the shutdown function in the pipeline. A forged steel gate valve is a widely used valve. It is generally used for closure devices with size ≤ 2 inches.
Features of forged steel slide valves
Forged steel slides usually have a reduced diameter. Compared with cast steel gate valves of the same size, the flow rate is slightly smaller, but the pressure and temperature range is wider than that of cast steel gate valves. Its sealing performance is much better than cast steel gate valves. It has a longer service life and the flow direction of the medium is not restricted.
Advantages of forged steel slide valves
- The fluid resistance of the forged steel slide is low, and the sealing surface is less rubbed and corroded by the environment.
- Forged steel gate valves are suitable for small diameter pipes of class 150 to 2500 with an operating temperature of -29 to 425°C (carbon steel) or -29 to 500°C (stainless steel) to shut off or turn on the fluid in the gas pipeline.
- Forged steel welded gate valves are simple in shape, short in length, easy to manufacture and widely used.
- The gate is mounted vertically on the valve body, and the flap of the globe valve is mounted horizontally on the valve body, so the length of the structure is shorter than that of the globe valve.
- The internal media channel of the forged steel slide valve body is straight, and the medium does not change its flow direction when flowing through the slide valve, so the fluid resistance is small.
- The flow direction of the medium is not restricted with a welded forged steel gate valve without disturbing the flow and reducing pressure. The sealing performance is very good, and the sealing surface suffers less erosion when fully opened.
Scope
Due to different materials, forged steel gate valves can be used for water, steam, oil, nitric acid, acetic acid, oxidative media, urea and other media.
