M70i and M80i sanitary ball valves for high-purity shut-off

M70I-AND-M80I

M70i and M80i sanitary ball valves for high-purity shut-off

The range is structured around line size as well as hygienic fabrication needs. M70i covers smaller sizes with forged 316L construction, while M80i extends the range into larger valve sizes with investment-cast 316L bodies and electropolished internal finish as standard. Both are aimed at high-purity shut-off duties rather than throttling control.

Choosing between M70i and M80i

The range is structured around line size as well as hygienic fabrication needs. M70i covers smaller sizes with forged 316L construction, while M80i extends the range into larger valve sizes with investment-cast 316L bodies and electropolished internal finish as standard. Both are aimed at high-purity shut-off duties rather than throttling control.

That distinction matters for buyers trying to match hygienic shut-off hardware to fabrication standards, media cleanliness and valve size without falling back to general-purpose ball valves that were not designed around dead-space reduction and drainability.

Typical high-purity media and duties

  • Clean steam and pure steam isolation
  • High-purity water and process liquids
  • CIP and SIP lines
  • Clean gases and utility branches
  • Manual or automated shut-off packages

Continue your high-purity valve selection

In high-purity systems, the shut-off valve has to fit the same hygienic and fabrication standards as the rest of the line, not just open and close reliably.
