1 Piece Stainless Ball Valve

Zhejiang Dafugui 1  piece stainless ball valve Introduction 

A 1 piece stainless ball valve" is a type of ball valve typically composed of a single-piece valve body and valve core, both made of stainless steel material. It has the advantages of a simple structure, small size, and light weight compared to multi-segment structure ball valves. This type of ball valve is suitable for pipeline switching and flow control and is widely used in fields such as petroleum, chemical, natural gas, and water treatment.

Zhejiang Dafugui 1  piece stainless ball valve Feature And Application

The structure of a ball valve can vary depending on its intended use. One type of structure is the load-bearing ball valve, which has good sealing properties but places all the load of the ball on the outlet sealing ring. As such, it's essential to consider whether the sealing ring material can withstand the working load of the medium. This structure is generally used in low to medium pressure ball valves.

Another type of ball valve is the fixed ball valve, where the ball is stationary and does not move under pressure. The floating seat of the valve moves under medium pressure, tightly pressing the sealing ring onto the ball to ensure a seal. This structure usually has bearings on the upper and lower shaft of the ball, resulting in low operation torque and making it suitable for high-pressure and large-caliber valves.

To further reduce operating torque and improve the reliability of the seal, there's an oil-sealed ball valve. In this type of valve, special lubricating oil is injected between the sealing surfaces under pressure, creating a layer of oil film that enhances the seal and reduces operating torque. This structure is particularly useful for high-pressure applications.
