High pressure butt welded ball valve

High pressure butt welded ball valves have strong adaptability to pressure and temperature changes due to the valve seat being composed of carbon fiber reinforced Teflon sealing rings and disc springs, and will not produce any leakage within the marked pressure and temperature range. The machining process of the sphere is tracked and detected by advanced computer detectors, so the machining accuracy of the sphere is high. Due to the fact that the valve body material is the same as the pipeline material, there will be no uneven stress or deformation caused by vehicles passing through the ground, and the pipeline is resistant to aging. The sealing ring body is made of RPTFE material with a carbon content of 20%, ensuring complete leakage free (0%).

1、 Working principle of high-pressure butt welded forged steel ball valve:

The high-pressure welded forged steel ball valve has a 90 degree rotation action, and the plug body is a sphere with a circular through-hole or channel passing through its axis. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. They can be tightly closed with only a 90 degree rotation and a small rotational torque. Ball valves are suitable for use as switches and shut-off valves, but recent developments have designed them to have throttling and flow control functions, such as V-shaped ball valves.

The main characteristics of high-pressure butt welded forged steel ball valves are compact structure, reliable sealing, simple structure, convenient maintenance, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium, easy to operate and maintain. They are suitable for general working media such as water, solvents, acids, and natural gas, and are also suitable for harsh working conditions such as oxygen, hydrogen peroxide, ethylene, etc. They are widely used in various industries. The valve body of a ball valve can be integral or modular.

2. Characteristics of high-pressure butt welded ball valves:

1. All components of this product are forgings.

2. Adopting embedded valve seats. Install an O-ring behind the valve seat to ensure that the medium does not leak out.

3. Adopting a bottom mounted valve stem with an inverted sealing structure to ensure reliable sealing at the packing and prevent valve stem detachment.

2 piece ball valve flange end

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status
