Due to the characteristics of the two-phase structure, through the correct control of the chemical composition and heat treatment process, the duplex stainless steel valve has the advantages of both the ferritic stainless steel valve and the austenitic stainless steel valve, and it combines the excellent toughness and the austenitic stainless steel valve. Weldability is combined with the higher st…

The eccentric hemispherical valve is a top-loading structure. The valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce the shutdown of the device and reduce the cost.…

Lift check valve refers to a valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and the dri…

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…
