New media separated valve series
The valve housing in fluid contact is made from thermally resistant poly phenylene sulphone (PPSU). Thus, it can withstand temperatures up to 98 °C / 208 °F. The material is approved by KTW (hot water) and W270 (microbiology). Furthermore, NSF 169 approved variants are available and other certificates can be achieved upon request.
In comparison to brass components, which may run the risk of lead contamination, the plastic valves are 100 % lead free. For food and beverage applications, this also shows the advantage that the plastic material does not affect the taste of the dispensed fluid. A further advantage occurs during operation, as the cooling of hot water in plastic components is much lower compared to brass and, therefore, delivers a more consistent temperature. In addition, the plastic surface shows less tendency to the build-up of calcium carbonate (lime scale).
A general benefit of lever valves is furthermore the hydraulic and electrical separation between liquid and valve parts. As well as media separation, lever valves also benefit from a reduced dead space. Due to their design, they are also robust and resistant to the effect of particles. A further advantage is the distance between the fluid path and solenoid, resulting in a thermal separation, allowing the handling of temperature sensitive media.
Therefore, lever valves are particularly suitable for dosing tasks and fluid delivery of liquids in food and beverage applications as well as temperature sensitive, aggressive, particle loaded or high-purity liquids in medical or analytical instrumentation or industrial applications.
