DIN Male Thread vs. Tri-Clamp Butterfly Valves: Which to choose?

Connection Type	Best Feature	Primary Application
DIN Male Thread	Extremely secure, handles high vibration and pressure drops well.	European brewery systems, high-pressure liquid transfer.
Tri-Clamp (TC)	Tool-less, rapid assembly and disassembly.	Frequent cleaning lines, North American dairy systems.

How to maintain the EPDM seal in a sanitary butterfly valve?

Routine CIP Cleaning: Ensure cleaning temperature does not exceed 135°C (275°F) for standard EPDM.
Visual Inspection: Periodically check the valve seat for swelling or micro-cracks caused by harsh acids.
Replacement: If the valve handle becomes too tight to turn, depressurize the line and replace the elastomer seal using our OEM repair kits.

Do you provide material test reports (MTR) for bulk valve orders?

Yes. As a verified ISO/CE certified manufacturer, Aomite provides complete Material Traceability Reports (MTR) for all 304/316L stainless steel bulk orders to ensure full compliance with your hygienic pipeline requirements.
