The soft sealing valve gate itself is a kind of valve with strong sealing performance. Its characteristics are widely reflected in other aspects. Compared with valves of other materials, it has many advantages in industrial production and can be used with confidence, so for For many manufacturers, it is a better choice.…

The cryogenic valve adopts the long-necked bonnet superior. The output liquid low-temperature medium, such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc., is not only flammable and explosive, but also needs to be gasified when heated up, and its volume expands hundreds of times when gasified. …

When used for cutting off, the plug valve has a slightly better adjustment ability than the ball valve, but the advantages are limited. Although the sealing surface of the plug valve is much larger than that of the ball valve, the sealing effect is good, so the torque is too large and the action is not flexible enough. Due to the influence of the weight of the cock itself, it is difficult for the …

Forged steel ball valves are steel used for casting castings. A type of cast alloy. Cast steel is divided into three categories: cast carbon steel, cast low alloy steel and cast special steel. Cast steel refers to a kind of steel casting produced by casting method. Cast steel is mainly used to manufacture some parts with complex shapes, which are difficult to be forged or formed by cutting and req…

Flanged forged steel ball valve has the function of rotating 90 degrees. The cock body is a sphere with a circular through hole or channel on the shaft. Ball valves are mainly used to block, distribute and change the flow direction of the medium in the pipeline. Just turn it 90 degrees to close the small torque tightly. Ball valves are suitable for use as on-off and globe valves, but recent develo…

The material of the two-piece forged steel ball valve is forged, and its density is much higher than that of castings. Especially suitable for the manufacture and processing of high pressure ball valves. The closing ball of the high pressure forged steel ball valve rotates around the centerline of the valve body to open and close. A ball valve is arranged at the end of the metal valve seat, in whi…

Low temperature forged steel ball valves are mainly used to close or connect the pipeline medium in the pipelines of various systems of thermal power plants. Applicable medium: non-corrosive medium, such as water or steam. Compared with other valve products, the forged steel ball valve has the characteristics of high temperature and high pressure, and the unique self-sealing design makes the seal …
