Industrial Oil/Water/Vapor Manufacturer&Supplier Stainless Steel Ball Valve

Product Description

The stainless steel ball valve only needs to be rotated 90 degrees and the torque is small to close tightly. The completely equal body cavity provides a straight-through flow path with minimal resistance to the medium. The main feature of the ball valve is that it is compact in structure, easy to operate and maintain, stainless steel ball valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.


The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.
Simple structure, small size and light weight.
Tight and reliable, the sealing surface material of the ball valve is widely used plastic, good sealing, and the working principle of stainless steel ball valve has also been widely used in the vacuum system.
Easy to operate, quick to open and close, and only needs to rotate 90°from full open to full closeed, which is convient for long-distance control.
Easy to maintain, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, and when the medium passes, it will not cause erosion of the sealing surface of the valve.
It can be used in a wide range of applications, from small to a few millimeters and several meters in diameter, from high vacuum to high pressure.



Stainless steel ball valve is a new type of valve that is widely used. It works by rotating the spool to keep the valve open or blocked. Only 90 degrees of rotation and a small torque are required to close tightly. The completely equal body cavity provides a straight-through flow path with minimal resistance to the medium.

A ball valve has 7 essential parts that make up its structure:

• Body and cover (3): These are the pressure retaining parts, being the container for the internal parts of the valves. The body is where all the parts are assembled.
• Ball (4): It is the element located in the flow passage that allows (or prevents) the flow inside the line, through a 90º turn on an axis perpendicular to the flow direction.
• Stem (1): This is the element that actuates the ball, and can be manually or automatically operated (electrically or pneumatically).
• Handle: This is the lever that allows the ball to be operated through the stem.
• Seats (5): These components, made of different materials, are positioned to hold the ball between the sealing surfaces of the seat itself, thus allowing the fluid to be hermetically sealed.
• Body seals: These are the elements that prevent fluid leakage to the outside between the body and the valve cover. They can be made of various materials.
• Valve stem seals (2): Valve stem seals are the sealing elements that are placed between the valve body and the valve stem to prevent leakage of fluid to the outside. They can be made of different materials.
