Diaphragm valves use a flexible diaphragm to isolate the flow path from the actuator, making them well suited to corrosive, abrasive, or high-purity (e.g., pharmaceutical, biotech) services. Selection considers diaphragm material (PTFE, EPDM, etc.), body lining, and weir vs. straight-through pattern.
Q: What is a diaphragm valve used for?
A: Diaphragm valves are used for corrosive, abrasive, or hygienic services where the process fluid must not contact the actuator mechanism.
Q: What diaphragm materials are common?
A: Common diaphragm materials include PTFE, EPDM, and butyl, selected for chemical compatibility with the process fluid.
Guidance reflects general engineering practice for diaphragm valves; confirm against the project specification and applicable standards before procurement.
