In the food and beverage industry, precision and reliability are the cornerstones of quality. We’re proud to offer a suite of fluid control solutions that not only meet these challenges head-on but also redefine the standards of beverage dispensing.

Limescale, composed of calcium carbonate deposits, can accumulate in dispensing equipment, leading to a host of problems. It can cause valves to stick, disrupt the consistent flow of liquids, and create hygiene concerns due to the potential for bacterial growth in the accumulated deposits. For OEMs, this means a risk of warranty claims, increased service calls, and potential damage to your brand. The costs associated with limescale are multifaceted. They include increased energy consumption as equipment efficiency drops, higher labour costs for cleaning and maintenance, and the potential for lost sales during equipment downtime. Moreover, limescale can shorten the lifespan of components, leading to more frequent replacements and additional expenses.

Understanding the critical impact of limescale, we have engineered a solution that stands apart. Our Fluid Control compact valve series is a game-changer for fully automatic professional coffee and drinks dispense machines. These individual valves are designed to reduce the surface area that limescale can build up on by simplifying complexity, space, and weight, supporting long uptime and minimising general maintenance.

Made from high-performance materials that meet NSF, FDA, and BfR standards, our valves are engineered to deliver leak-free performance essential for controlling cold, hot, and carbonated water, as well as steam and aggressive processes.

With our innovative design, we prevent limescale build-up for a more hygienic dispensing process, extend the life of dispense equipment, and reduce maintenance with our premium components.

Our small footprint and manifolding options also allow equipment manufacturers to simplify their designs, optimising both fluid and electrical connections. Our valve manifolds can also be integrated with pressure and flow sensors to fully automate the central system providing essential feedback to the user on the fluidic system performance.
