Description

Servo-controlled valve nominal diameter DN 10, which closes by means of buoyancy of a floater to control level in tanks. If liquid is drained from the tank, the float valve refills automatically and closes when the maximum level has been reached. 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. Applications Irrigation systems high pressure cleaning devices Ice machines Industrial appliances Characteristics redirection of flow by 90° operation largely independent from inlet pressure Easy to assemble and service Compact design for heated water up to 60 °C adjustable level height High operating safety through the use of high quality materials and 100% final testing of the products
