About this model

Same casting pattern as the ductile iron version, in stainless. The reason to take this one is the medium: chlorides, dilute acids, food and pharmaceutical duty, or a stainless line where a painted iron body would be the odd part out.

Because the body pattern is shared, DN50 to DN600 and both actuator types carry over unchanged. A stainless valve replaces an iron one on the same bolt holes.

Tell us the medium, the concentration and the temperature and the stainless grade is fixed from that. We do not quote a grade before the duty is known — the wrong one is an expensive mistake on a DN300 body.

Design features

  • DN50 to DN600 in one series
  • Stainless body, wafer pattern with lugged ports
  • Rising stem with a bolted gland
  • Handwheel, lever or pneumatic cylinder on the same yoke
  • Shares the flange drilling with the ductile iron version
  • Grade selected against the actual medium, not a default

Applications

  • Food and beverage — product and CIP circuits
  • Chemical — corrosive and chloride-bearing media
  • Pharmaceutical — cleanable wetted path
  • Water treatment — dosing and filter lines
  • Marine and offshore — salt-laden atmospheres

Packing

Port faces boarded, stem wrapped, actuator braced. Carton for the smaller sizes and a case above DN200. Neutral packing as standard; private label available.

Custom options

Tube and stem lengths outside the standard range, alternative seal materials and private labelling are quoted per order. Send the drawing or the dimensions you need and we will confirm what is possible before quoting.

Need this in a different length or material?

Stem length, outlet bore, seal material and labelling are the four things customers change most. Send your requirement and we will quote it.
