Diaphragm specification
Confirm the fluoropolymer face, backing elastomer and any process-required documentation.
Fluoropolymer-lined diaphragm valve
PFA-Lined Diaphragm Valves
DN15–DN300 lined diaphragm valves with manual and pneumatic configurations. Diaphragm materials, backing construction and the full service profile are reviewed together.
Isolation mechanism
A flexible diaphragm separates actuation from the lined flow path
This valve family may be screened when a diaphragm mechanism and fluoropolymer-lined wetted construction fit the process concept. The exact diaphragm assembly remains a service- and model-specific decision.
- DDiaphragm isolation mechanism
The diaphragm separates the operating mechanism from the catalog-described lined flow path.
- CConstruction-dependent materials
Fluoropolymer and elastomer backing references vary; the complete diaphragm specification is required.
- PManual or pneumatic route
Pneumatic selection requires the control function, air supply, fail action and cycling information.
