DIAPHRAGM VALVES
PECM is used to machine the complex internal features of diaphragm valves, which are essential for sanitary applications in industries like food, pharma, and biotech. It is the ideal solution for creating the intricate weir and seat pocket.

Materials Machined
- Stainless steel (316L, etc.)
- Hastelloy and other corrosion-resistant alloys
- Nickel-based alloys
- Cast and Forged bodies
Market Sectors
- Pharmaceutical: Bioreactors and high-purity fluid systems.
- Food & Beverage: Dairy and food processing lines.
- Medical: Sterile processing equipment.
- Chemical Processing: Corrosion-resistant valves and pumps.
- Cosmetics: smooth, high-precision surfaces
Key Benefits & Numbers
- Faster Machining: Machines the entire internal geometry in a single, non-contact operation, reducing cycle time by over 80% compared to traditional finishing
- Sanitary Finish: Produces a smooth, burr-free interior that meets strict ASME BPE standards, essential for preventing bacterial growth.
- High Accuracy: Maintains dimensional tolerances with an accuracy of ±25 µm on complex internal shapes.
- Weld Correction: Can be used to correct internal distortion caused by welding, improving the internal surface roughness from Ra 1.6 µm down to Ra 0.2 µm.
Relevant Industry Standards
- ASME BPE: The primary standard for bioprocessing equipment and its components, specifying material, design, and fabrication requirements.
- ASTM E2536: Standard Guide for the Design, Manufacture, and Cleaning of Bioprocessing Equipment.
- ISO 2037: Welded stainless steel tubes for the food industry.
