The Frese ALPHA HCR (High Corrosion Resistant) valves are particularly designed and manufactured for automatic balancing in industrial applications.

An integral part of the Frese ALPHA HCR Valve is the ALPHA Flow Cartridge, whichs limits the flow to a specified level at all times, regardless of fluctuating pressure conditions.

The patented design of the stainless steel ALPHA flow cartridge introduces an interchangeable orifice plate for design flexibility and a resistant diaphragm for high accuracy operation. The Frese ALPHA HCR valve can also be installed with the ALPHA HCR cartridge for other highly corrosive applications.

Available as standard up to DN300 and with other materials up to DN125 on request. Frese ALPHA HCR valve guarantees the hydraulic balance of the system regardless of pressure fluctuations.

The introduction of the Frese ALPHA HCR pressure independent flow limiting valves enables Frese to offer the benefits of dynamic balancing to a variety of new, exciting industrial applications including oil & gas installations, petrochemical plants, pharma

installations and other industries where there is a need for high corrosive resistant balancing valves.

The Frese ALPHA HCR flow limiting valve works independently and therefore it can be installed in either single or multiple parallel distribution lines. Furthermore, the independent nature of the valve provides total system flexibility with no re-commissioning required

should the system be extended. In addition, it is also possible to use back flush processes with the Frese ALPHA HCR pressure independent flow limiting valve if necessary.
