- Discover Alfa Laval UltraPure for a Secure, Safe and Efficient Pharmaceutical Water System

Alfa Laval’s DV-ST valve is highly suitable for the demands of pharmaceutical water systems. The compact, lightweight diaphragm valve is modular in design, which enables a wide range of purpose-built configurations. It consistently delivers documented, reliable and contaminant-free performance due to specified sulphur content that contributes to superior weld quality and high-quality valve bodies with low delta-ferrite.

NEW: 4” version of the DV-ST has recently been added to the extended valve range meeting customer wishes. It is built on 3” components without compromizing Kv values, but adding the benefit of utilizing same diaphragm, handle and actuator for both 3” and 4” minimizing stock keeping.

Water is an essential ingredient to pharmaceutical manufacturing. Once purified, non-compendial water, purified water or water for injection must be stored and distributed in systems appropriately designed, installed, commissioned, and validated. Controlling the water quality in the distribution loop to ensure delivery to the point of use at the required flow and temperature can be challenging. This is why pharmaceutical manufacturers look for sustainable, energy-efficient solutions to deal with rouging, biofilm build up or other impurities in the water distribution loop.

Pharmaceutical water systems serve the purpose of maintaining water quality within acceptable limits. The water is delivered to the point-of-use at the required flow and temperature whilst providing ease of validation of all equipment, spare parts, and service kits, in order that the capital investment and operating expenses are minimized.

Relying on Alfa Laval as a single supplier to help meet the stringent demands of pharmaceutical water systems, it’s easy to comply with all the pharmaceutical requirements for safety, hygiene, economy, energy-efficiency and reduced waste simply by taking advantage of our vast pharmaceutical process expertise, broad and proven hygienic equipment and global service network.

Portfolio Manager for Valves and Automation at Alfa Laval, Paw Kramer comments: “using our high grade single layer EPDM diaphragm minimizes hidden cross contaminations or biofilm build up.”

Further benefits of using the Alfa Laval DV-ST UltraPure in water systems include:
- Ensuring safe, long-term operation of pharmaceutical water systems,
- Minimizing the risk of rouging due to high-quality welding,
- Saving energy, easing installation and making steam sterilization more efficient,
- Minimizing the risk of contamination from all standard valves due to a leak detection hole,
- Reducing energy use for heating and putting less stress on the piping due to reduced weight.
