JG Underfloor Angle Ball Valve is a service valve that isolates supply to the underfloor heating (UFH) manifold and control pack. The ball valve connects the main heating flow and return pipe to the mixing valve, while allowing the supply to the control pack to be safely isolated for maintenance purposes. The angle design allows it to be used in both vertical or horizontal pipe arrangements.
