Lined Valves
PFA/PTFE/FEP-lined protection for the most aggressive chemical service
Purpose-built for corrosive and ultra-pure media, these fully-lined ball, plug, butterfly, and check valves use PFA, PTFE, or FEP linings to protect wetted surfaces. Designed for zero contamination and long service life in acid, caustic, and chlorine applications.
When metal valves corrode in weeks, lined valves deliver years of reliable service. Zero contamination of process media and no corrosion products in the flow stream.
As an authorized Crane / Resistoflex partner, we offer lining material selection, compatibility consulting, and spare lining kits for in-plant maintenance.
Engineered
where it matters
Full PFA/PTFE lining
Complete isolation of wetted surfaces from corrosive media — no metal contact with process fluid.
Zero contamination
Ultra-smooth fluoropolymer surfaces prevent product contamination in pharmaceutical and chemical processes.
Multi-valve range
Ball, plug, butterfly, check, and diaphragm valves all available in lined configurations for full-line coverage.
Antistatic design
Conductive path from handle to body prevents static charge build-up in flammable or explosive environments.
Permeation-resistant
Advanced PFA grades resist permeation by HCl, bromine, and chlorine gas that degrade standard PTFE.
Fire-safe option
Secondary metal seat provides fire-safe shut-off per API 607 when fluoropolymer lining is compromised.
