Flowflex Float valves provide a mechanism to fill water tanks, such as toilet cisterns. As the water level rises inside the tank, a float rises as well forcing the valve to shut and therefore stopping the flow of water. Our range of brass float valves can be used for water tanks, troughs.
Flowflex operates a quality management system audited by the British Standards Institute for the manufacture and supply of fittings and components for use in all applications of the HVAC industry.
All installers should ensure that the size of the valve matches the size of the tube, whilst also ensuring both are in good condition and free from damage and imperfections.
Flowflex valves are designed to connect BS EN 1057 tube.
