Lead free solenoid valves

Safe drinking water installations

The Drinking Water Directive 98/83/EC defines a maximum lead content of 10 µg/l in drinking water for the European Union. This limit came into force on 01.12.2013.

In the USA the Safe Drinking Water Act came into effect in 2014. Along with the ‘Reduction of Lead in Drinking Water Act', the ‘Safe Drinking Water Act' limits the lead content to 0.25 % in total for all installation components such as pipes, fittings and fixtures used to convey or dispense drinking water.

Thus, the selection of suitable materials is one of the most important aspects of sustainable and safe drinking water installations. Therefore, lead-containing metal components such as brass should be eliminated to be on the safe side.

The solenoid valve manufacturer A. u. K. Müller have already been using plastic materials in contact with media for years. By using high-performance plastics, both the high mechanical stress on the valve and the strict requirements for components in drinking water applications can be fulfilled. Thus, the installer either from the sanitary, vending or food processing market is not left alone with questions regarding their use with potable water. The variety of servo, cartridge or direct-acting solenoid valves offered, as well as accessories such as strainers, pressure reducing valves, backflow preventers or distribution systems are available as certified versions according to KTW/W270, NSF61, WRAS and ACS.

By applying these distribution systems in combination with the valves it is also possible to implement completely lead-free systems. An example of this is the combination of compact valve series 18.000 with the push fit system FitSys 18 already in used in vending machines.

Control valve for potable water

Furthermore, the dosing of constant volumes or the design of controlled fluidic paths can easily and smoothly be realized without water hammer by the linear motor. The valve is also an efficient and optimal solution for low flow rates without a complete shut off function. With a pressure range from 0 – 10 bar the valve is used e.g. in hot and cold vending machines, in cl...

NEW: Servo-controlled angle valve DN 7

The elbow nozzle design of the new servo-controlled angle valve with the nominal orifice of DN 7 is a space saving solution particularly for narrow installation conditions. The materials in media contact are approved for drinking water and 100% lead-free. UL, WRAS, VDE certified variants are available. Furthermore, the valves are suitable for hot water up to 90 °C. Therefore, they are ideal as inlet valves in potable water applications.

Further advantages of the valve series is its short closing time, allowing a precise control, for example when filling tanks. Despite the high flow rate with a Kv value of 12.4 l/min and the short closing time, the valves fully meet the requirements of EN 60730 in terms of water hammer. Typically the angle valves are available with a G ¾ threaded inlet and a 11.5 mm noz...

The valve solutions consist of food-approved materials, which can be optionally equipped with a PTFE valve seat, inhibiting the build-up of lime scale and contributing significantly to the prolonged life of the components. The actuators of the valves are media separated by a membrane. The valves are offered either, as a cost effective one-piece valve housing, or as an e...
