Typical Industrial Case: Dairy CIP Automation

A leading European dairy plant upgraded to stainless steel sanitary butterfly valves (Model 25, SS316, PTFE seat) to automate Cleaning-in-Place (CIP) lines, boosting process uptime by 23%, minimizing contamination risks. Valves supplied passed EN10204-3.1 traceability, 3A and FDA compliance, and delivered 120,000 cycles maintenance-free.

6. Cost Comparison: SS Butterfly Valve Pricing & Value Analysis

The choice between ss butterfly valve, ss 304 butterfly valve, ss body butterfly valve and pvdf butterfly valve depends on the media, environment, and required standard. Below is a real-world indicative price comparison based on international market data (Q2 2024) for DN80/PN16/hand lever valves:

Bulk order, international certification requests, or special alloys (Duplex, Alloy 20) may increase the ss butterfly valve price by 12–28% above the base range.
