Description

The DN 10 float valve in the straight-through version is a servo-controlled diaphragm valve that closes by the buoyancy of the float to regulate the level in containers. The float valve automatically replenishes the water when it is removed from the tank, thus keeping the level constant. If the water level rises and lifts the float in the container, the inflow is reduced in proportion to the position of the float lever. Overflowing of the tank as a result of too much inflow into the tank is thus effectively counteracted. The float valve is a 1-chamber globe valve made of glass-fibre reinforced polyamide. It can be manufactured with different housing connections. The float valve can be equipped with a multi-position lever. The universal lever can be adapted to a wide variety of tank geometries without tools. In addition, the lever can be shortened for use in smaller tanks. With the optional stainless steel float ball for the multi-position lever, the valve is suitable for heated water up to max. 90 °C. Applications high pressure cleaning devices (system separation according to EN 1717) washing systems Irrigation systems Ice machines Characteristics proportional behaviour (flow depends on position of float lever) Servo-controlled operation largely independent from inlet pressure Easy to assemble and service float adjustable on thread rod thread rod can be shortened at predetermined breaking points different lever lenghts available High operating safety through the use of high quality materials and 100% final testing of the products Technical data Function closed by buoyancy of float Fitting position float vertically downwards T-Ambient as per T-Medium
