Precision metal diaphragms act as the flexible sealing and force-transmitting element in high-purity valves. Reliable performance depends on the combined control of alloy condition, thickness, formed geometry, heat treatment, surface condition, assembly load and operating cycle.
Material Options
- UNS R30003 cobalt-based alloy — considered for demanding applications requiring high strength, corrosion resistance and fatigue performance, including customer-specified Phynox® or Elgiloy® grades.
- Alloy C22 / UNS N06022 — considered where aggressive process chemistry places additional demands on corrosion resistance.
- Other corrosion-resistant alloys — reviewed according to the drawing, process media and qualification requirements.
Project Support
- Strip and raw-material sourcing with certificate review
- Material condition, diaphragm profile and stack configuration review
- Forming and heat-treatment process coordination
- Surface finish, polishing, cleaning and packaging requirements
- Dimensional inspection and project-specific qualification documentation
Information Required for Quotation
Please provide the valve application, drawing, diaphragm diameter and thickness, formed profile, number of diaphragms per stack, process media, pressure, temperature, target cycle life, surface and cleanliness requirements, prototype quantity and estimated annual demand.
Final material availability, manufacturing route, tolerances, testing and documentation are confirmed for each project before supply.
