Evidence scope

The retained official product route documents: Alfa Laval documents Unique DV-ST Ultrapure as an aseptic modular diaphragm valve for pharmaceutical, biotechnology and hygiene applications. This dossier uses that cited route as the editorial scope. [S9]

The retained research coverage separates company identity from the named product evidence. It does not turn one model or series into a claim about unlisted company-wide operations. [S11]

  • Alfa Laval Unique DV-ST Ultrapure aseptic modular diaphragm valves with manual or pneumatic operation. [S6]

Selection fit: Start with Unique DV-ST Ultrapure for its stated aseptic pharmaceutical, biotechnology or hygiene context, then verify body, diaphragm, actuator, pressure and steam conditions for the selected configuration with Alfa Laval. [S10]

Self Cleaning Filter

Documented series: ALF is available with stainless steel, fiberglass-reinforced polyester or rubber-lined carbon-steel casings and a stainless cylindrical filter basket.

Alfa Laval publishes the ALF self-cleaning filter to protect heat exchangers in industrial secondary-water cooling systems. [S14]

Documented specifications for Self Cleaning Filter
Materialstainless steel [S17]
  • ALF is available with stainless steel, fiberglass-reinforced polyester or rubber-lined carbon-steel casings and a stainless cylindrical filter basket. [S7]
  • Alfa Laval LKH Prime self-priming centrifugal pumps for hygienic process lines with entrained air and CIP duties. [S8]

Selection fit: Shortlist ALF for secondary-water cooling duties where heat-exchanger fouling, clogging and corrosion protection is the stated need. Confirm water quality, debris type, materials, mesh, flow, pressure drop, backflush disposal, maintenance kit and service directly with Alfa Laval before order. [S15]

Procurement fit

For diaphragm valves, the documented recommendation is to start with the Unique DV-ST Ultrapure series where an aseptic pharmaceutical, biotechnology or hygiene context applies, then verify body, diaphragm, actuator, pressure and steam conditions for the selected configuration with Alfa Laval. For self-cleaning filters, the ALF series is shortlisted for secondary-water cooling duties where heat-exchanger fouling, clogging and corrosion protection is the stated need. Water quality, debris type, materials, mesh rating, flow, pressure drop, backflush disposal, maintenance kit and service should be confirmed directly with the manufacturer before order placement.

Technical capabilities

The Unique DV-ST Ultrapure diaphragm valve is documented in stainless steel with a modular body, diaphragm and actuator or handle architecture using a weir-type arrangement. Stated diaphragm materials are EPDM, PTFE/EPDM and M-PTFE. Pneumatic versions are rated up to 10 bar depending on selection, and EPDM is rated for continuous-steam use up to 150 °C. The ALF self-cleaning filter is documented with casings in stainless steel, fiberglass-reinforced polyester or rubber-lined carbon steel, paired with a stainless cylindrical filter basket and a stated supply length of 110 m.

Markets and applications

The Unique DV-ST Ultrapure diaphragm valve is positioned for aseptic pharmaceutical, biotechnology and general hygiene service, with manual or pneumatic actuation suited to skid or process-line integration. The ALF self-cleaning filter is positioned for secondary-water cooling circuits where fouling, clogging and corrosion protection of downstream heat exchangers is the stated requirement. Both product lines are documented at the series level only, and specific project suitability, sizing and media compatibility are not publicly documented here and must be reviewed against the actual service conditions with Alfa Laval.

Evidence limitations

Items not publicly documented in the available source material and therefore not stated in this profile include pricing, regional availability, lead time, current certifications, agency approvals, dimensional drawings, full material traceability, surface finish grades, mesh ratings for the ALF basket, full pressure-temperature envelopes across all diaphragm variants, and any post-sale service agreements. The Unique DV-ST Ultrapure and ALF series designations are the only model codes on record. The reference list also names LKH Prime in procurement-fit context, but its technical specifications are not publicly documented in the supplied material.

Editorial summary

Alfa Laval is a Sweden-based manufacturer headquartered in Lund with documented product coverage in two categories relevant to this directory: diaphragm valves and self-cleaning filters. The diaphragm valve offering is represented by the Unique DV-ST Ultrapure series, described as aseptic modular units available with manual or pneumatic operation. The self-cleaning filter offering is represented by the ALF series, with stated stainless cylindrical filter basket construction. Specification details captured here are limited to what the referenced documentation discloses, and further product data should be requested directly from the manufacturer for engineering and procurement evaluation.

Frequently asked questions

What Diaphragm Valve product is documented for Alfa Laval?

The retained product material names Alfa Laval Unique DV-ST Ultrapure aseptic modular diaphragm valves with manual or pneumatic operation. The dossier keeps this as a product-level statement rather than using it as a claim about the company's entire catalogue. [S6]

Which published hygienic configuration should a buyer compare?

The cited product material records: Unique DV-ST Ultrapure has modular body, diaphragm and actuator or handle components, with a weir-type arrangement. Use the value as a product-level comparison point, while keeping the exact model and installation boundaries in the cited route. [S4]

Which published materials and stated limits should a buyer compare?

The cited product material records: The page lists EPDM, PTFE/EPDM and M-PTFE diaphragms; pneumatic versions are stated up to 10 bar depending on selection and EPDM continuous-steam use up to 150 °C. Use the value as a product-level comparison point, while keeping the exact model and installation boundaries in the cited route. [S5]

Which common buying fields are not published in the retained sources?

The retained source packet does not publish Annual sales, Certifications, Availability or stock. Those fields are intentionally left out of the procurement snapshot rather than inferred from a related series, a product image or the company identity. [S11]

Research notes

The retained first-party packet supports a richer product-level reading surface, but it does not yet contain 600 words of distinct cited content. This noindex dossier remains in reviewing status until additional source-backed facts are retained.
