What is the difference between M70i and M80i sanitary ball valves?

The M70i uses a forged 316L body for sizes ½" to 2" with <1% ferrite content. The M80i uses investment cast 316L for sizes 2½" to 4" with <5% ferrite content. The M80i also comes electropolished as standard, while the M70i is mechanically polished with electropolishing available as an option.

Can these valves be automated with pneumatic actuators?

Yes. Both models include ISO 5211 mounting pads as standard, allowing direct attachment of Spirax Sarco BVA200 series pneumatic actuators and LSB type limit switches. Contact PC Engineering for actuated valve assemblies.

Are material test reports included with the valves?

Yes. Spirax Sarco provides MTRs and certificates of compliance as standard with every M70i and M80i valve, meeting documentation requirements for validated pharmaceutical and high purity systems.

What surface finish options are available?

The M70i is supplied mechanically polished to 0.5 micron Ra (20 micro-inch) as standard, with electropolishing to 0.375 micron Ra (15 micro-inch) available on request. The M80i is electropolished to 0.375 micron Ra as standard.

Are these valves suitable for steam service?

Yes. The high temperature Dyneon TFM™ seats make both models suitable for continuous clean steam and pure steam service, as well as CIP/SIP cycles.

Overview

The Spirax Sarco M70i and M80i sanitary ball valves are precision-engineered for high purity process applications where system integrity and product quality are critical. Manufactured from 316L stainless steel and designed in accordance with ASME BPE standards, these valves meet the stringent requirements of pharmaceutical, bioprocessing, food and beverage, and semiconductor industries.

The M70i covers smaller line sizes (½" to 2") with a forged 316L body, while the M80i handles larger requirements (2½" to 4") using investment cast 316L construction. Both models feature true port design that precisely matches connecting tubing diameters, eliminating dead spaces where bacteria and media deposits can accumulate. This ensures free draining and reduces contamination risk.

Spirax Sarco supplies material test reports (MTRs) and certificates of compliance as standard, addressing documentation requirements essential in regulated high purity environments.

Key Features

True port design – Internal diameter matches tubing size, eliminating dead spaces and enabling free draining
316L stainless steel construction – Low ferrite content (<1% M70i, <5% M80i) per ASME BPE requirements
FDA and USP Class VI compliant seals – High temperature Dyneon TFM™ seats and cavity fillers as standard
Orbital welding compatible – Tube weld end tangent lengths per ASME BPE for consistent, fully penetrated welds
ISO 5211 mounting pads – Standard actuator and limit switch mounting capability
Lockable handle – Included as standard for safety and process control
Cavity filler design – Eliminates crevices around ball that can harbour bacteria
