RS PRO, Bottom Entry, Float Valve, 1/2in

Use this RS PRO float valve to control liquid levels in your tank. It works by detecting variations in the liquid level and opening or closing accordingly. You can install it through a bottom inlet on most tanks and cisterns.


The valve is made of engineering resin, which has a tensile strength of 4 tonnes for a strong and long-lasting component. It has a filter that can be removed and cleaned easily. A half-inch male thread runs through the tail for a simple yet secure connection.


The valve has been authorised for use in installations conveying water from the public mains supply by the Water Regulations Advisory Scheme (WRAS). It can withstand pressures of 0.15 bar to 14 bar, making it suitable for a range of applications. This type of float valve can be found in reservoirs, storage tanks and condensate tanks.
