The definition, material and application of PTFE lined ball valve

What is the definition of PTFE lined ball valve?

PTFE lined ball valve is a kind of valve, the inner sphere and the pipe are lined with fluorine plastic (PTFE) and other materials, which can prevent the medium from corroding and leaking the valve. The ball of the PTFE lined ball valve can rotate 360 degrees to achieve rapid fluid cutting and flow regulation. PTFE lined ball valves are suitable for pipeline systems that transport corrosive media such as acids, alkalis, salts, and organic solvents, and are widely used in chemical, pharmaceutical, food, metallurgy, and electric power industries.

What are the materials of PTFE lined ball valves?

Different lining materials are suitable for different media. When selecting the material, you should choose it according to the nature of the medium and the working environment conditions.

Body: cast steel, ductile iron, stainless steel, etc. The surface is usually sprayed with plastic or rubber.

Lining: fluoroplastic (PTFE), chloroprene (CR), fluororubber (FKM) and other materials, with excellent corrosion resistance.

Seals: PTFE, fluororubber (FKM) and other materials, with good sealing performance, high temperature resistance and corrosion resistance.

Ball: stainless steel, chromium-molybdenum steel, titanium alloy and other materials, with high hardness and corrosion resistance.

Handle: cast aluminum alloy, stainless steel and other materials, easy to operate.

Where is the PTFE lined ball valve used?

PTFE lined ball valves are suitable for transportation systems of various chemical media, such as petroleum, chemical, pharmaceutical, food and other industries. Its main feature is that the inner cavity of the valve body is made of PTFE lined material, which can effectively resist the erosion of strong acids, strong alkali, and highly corrosive media. It has excellent corrosion resistance, making it widely used in control systems of various corrosive media. Such as: acids, bases, salts, oxidants, organic solvents, etc.
