NEW product: Assisted lift, servo-controlled valves

Specifically for high flow valve applications with little or no differential pressure, A. u. K. Müller has developed assisted lift servo controlled valves, series 31.010 and 31.013 with nominal width DN 10 and 13. Made from plastics, the valve body consists of glass-reinforced polyamide, which is suitable for hot and deionized water. For the metallic internal components in media contact, corrosion-resistant stainless steel is used. The overall system is approved for use with drinking water according to KTW/W270. WRAS and ACS can be realised on customer request.

Technically assisted lift, servo-controlled valves are perfectly suited for valve applications where the differential pressure is very low or almost zero. The functional principle is based on the mechanical coupling of the valve membrane to the plunger. Therefore, the valve acts as a direct operated valve in the low-pressure range and a servo-controlled valve in the high-pressure area. Thus, at high pressures, relatively high flow rates can be achieved. Furthermore, a high reliability over a wide pressure range is accomplished since the function is independent of the differential pressure between the inlet and outlet.

Therefore, the assisted lift, servo valves are ideally suited for low-pressure applications requiring a high volume flow as for example in tanks.

The 2/2-way solenoid valves are available with various connectors and furthermore the user can select from different coil systems for common voltage and frequency ranges.

The advantages at a glance

• Combining the positive features servo-assisted and direct switching valves

• Opens without differential pressure, normally closed without differential pressure

• Nominal widths DN 10 and DN 13

• Suitable for hot water up to 90 °C/194 °F

• Applicable with potable water; certified according to KTW/W270

• By applying the servo principle smaller and energy-saving coils can be used compared to direct acting valves

• Universal use for high flow applications at low pressures as in tanks or circulation systems
