Our comprehensive range of water solutions includes products that are specifically designed to provide backflow protection for Fluid Category 4 risks. These are fluids that pose a significant danger to health because of the concentration of toxic substances that they contain. This includes, for example, any fluid with pesticides (including herbicides and insecticides), chemical or carcinogenic substances or environmental organisms of potential health significance.
Our Fluid Category 4 products include Pent-A-Boost booster pumps, reduced pressure zone (RPZ) valves, Autofill units and DB pipe interrupters. To prevent contaminated water flowing backwards, the solutions feature an air gap Type AF or equivalent, or a mechanical valve arrangement. These systems are required for a variety of applications, including commercial heating systems, bottle washing apparatus, dyeing equipment, commercial dishwashing machines and brewery and distillation plants.
You will find our full range of RPZ valves and other Fluid Category 4 products on this section of our website. We are also able to manufacture bespoke assemblies, so if you can’t see solutions that match all of your practical requirements, don’t hesitate to contact us with your specifications.
