Series 21.010.110

Product catalog summary

Product Overview: The document provides detailed information about the Float Valve, DN 10, manufactured by A.u.K. Müller GmbH & Co. KG. This valve is designed for controlling liquid levels in tanks through a servo-controlled mechanism that utilizes the buoyancy of a floater.

Applications: The valve is suitable for tank filling, irrigation systems, high-pressure cleaning devices, ice machines, and various industrial appliances.

Key Characteristics: The valve features a servo-controlled mechanism, a 90-degree flow redirection, and operates largely independent of inlet pressure. It is compact, easy to assemble and service, and suitable for heated water up to 60°C. The valve ensures high operating safety through the use of high-quality materials and 100% final testing.

Technical Specifications: The valve body is made of PA 66 glass fiber reinforced material, with EPDM membrane and sealings. It is a 2/2-way single chamber valve with an adjustable float body position and a filter fitted in the inlet. The valve operates within a pressure range of 0.3 to 10.0 bar and has a Cv-value of 28 l/min.

Options and Versions: Various versions are available upon request, including different flow restrictions and materials for specific components like the float cylinder and filter. The document also outlines the potential approvals such as KTW/W270 and WRAS.

Performance and Recommendations: The document includes a typical performance curve and recommendations for flow restrictions based on the tank's water surface area and required inflow rate.

The outlet jet is directed on to a guide, which pushes the lever to closed. This effects a relative constant flow, covering a wide pressure range. An overflow of small tanks will be prevented during the initial filling. By reaching a sufficient level within the tank during refill, the final closing procedure is due to the buoyancy of the float body. Valves of this design are single chamber valves with the inlet ninety degrees to the outlet. The valve, having a glass fibre reinforced polyamid housing, can be manufactured with various connections and is suitable up to 60° by using a PE-floater. © copyright A.u.K.

Product Information Float Valve, DN 10 Guide lever Flow regulator in inlet The individual flow rate has to synchronised with the water surface area within tank at float level height No flow restriction. A restriction of the pressure range (e.g. 0,5 - 8 bar) may be recommended, if the rise of the water level within the tank may lead to an overflow by a gush of water. Flow restriction above 1,5 bar to approx. 35 l/min. Flow restriction above 1 bar.
