PTFE-Lined Valves

PTFE-Lined Valves

Lined valves are the safe and reliable solution to any level of corrosion hazard.

Lined valves can be used as more economic alternatives to high-grade alloys in corrosive applications in the chemical, pharmaceutical, petrochemical, fertilizer, pulp and paper, and metallurgical industries.

The lining of the valves and fittings ensures an extremely high chemical resistance and longevity. The valves are leak-free and have minimal operating and maintenance costs. In addition to the standard FEP+PTFE lining, we can also offer anti-static lining from PFA+PTFE.

BERG offers a complete range of lined ball valves, ball check valves, swing check valves, diaphragm valves, butterfly valves, sight glasses, as well as lined pipes and fittings.

Special designs and materials are also available on request.
