What is A Lined Ball Valve?

A lined ball valve uses a fluoropolymer or ceramic lining applied to all wetted internal parts of the valve.

Lined valves combine the excellent mechanical properties of metallic bodies with the corrosion resistance of fluorocarbons, such as PFA and PTFE.

Lining the intricately shaped inside surfaces of a valve is certainly an engineering challenge, especially to achieve a uniform thickness and the highest lining quality, without cavities or inclusions.

The special lining process guarantees tight bonding between the lining and the inside of the body. This effectively prevents the lining from shearing off the body in part or being removed completely.

Special options, such as reinforced PTFE bellows seals or adjustable packings, can be accommodated. Bellows seals made of special metals, such as titanium or Hastelloy, are available as options as well.

Lined ball valves are ideally suited for corrosive applications, requiring very reliable performance, tight shutoff, constant torque and no maintenance. Lined ball valves can successfully be applied to a wide range of corrosive applications in industries such as chemical, petro-chemical, pharmaceutical, and pulp and paper.
