    Reliance Valves Nickel Plated Lever Ball Valves are used in water applications to allow appliances or sections of plumbing within a building to be switched off, without the need for draining the whole system. The brass ball valve reduces and stops water flow, creating an isolation after the valve position. Reliance quarter turn ball valve fittings are available with a blue or red handle to help distinguish usage (generally hot and cold) and are EN331 compliant.Typically, brass ball valves can be found at appliance outlets, such as washing machines and dishwashers to allow water supply to be cut off for installation and maintenance. We also offer in line washing machine valves with smaller handles which can be used in limited space areas.Reliance Valves Nickel Plated Lever Ball Valves can also be used under kitchen or bathroom sinks to allow users to control tap water flow. Used in place of a standard service or isolation valve, a quarter turn valve can provide a more robust, easy to use shut off option for temporarily stopping water supply. Due to the large handle, these valves are also recommended for use in specialist situations where the smaller screw type ball valves may not be suitable.The quarter turn ball valve is also available with Speedfit connections, for fast, secure and tool-free installation.Features and benefits Range of full bore ball valves Nickel plated PN40 or PN25 FBSP variants available Easy to use lever handle with clear colouring to designate usage: red and blue for hot and cold water in accordance with EN331 Not suitable for chilled water
