PTFE Lined Valves for Vacuum Service: Buyer Guide | Vcore

Quick Summary: PTFE lined valves for vacuum service must be selected by the complete valve design, minimum absolute pressure, temperature during vacuum exposure, chemical composition and operating cycle. Chemical resistance and a positive-pressure rating do not establish vacuum suitability. Before ordering, obtain model- and size-specific confirmation of lining support, sealing performance and the applicable vacuum–temperature […]
PTFE Lined Diaphragm Valve vs Plug Valve for Corrosive Chemical Service

Quick Summary: When comparing a PTFE lined diaphragm valve vs plug valve for corrosive chemical service, the main selection factors are stem isolation, internal flow resistance, lining integrity, sealing materials, operating frequency, temperature and maintenance requirements. A lined diaphragm valve separates the stem and operating mechanism from the process medium through a flexible diaphragm. A […]
