Intact tap connections, hose couplings and hoses form the basis of watering effectively. This is why Kärcher provides a complete range of accessories for connecting, disconnecting, controlling and repairing watering systems. For example Kärcher's control valve – the ideal solution for controlling the water flow from 0 to max. It features an ergonomic design for easy handling. The control valve can be used for connecting the hose and sprinkler or, with the 2-way coupling, for connecting two hoses. Kärcher's control valve is compatible with all available click systems and all common hose diameters.nn- For watering small to large areas and gardens.n- For watering large gardens.n- For watering food plants and useful plants (small beds, individual and potted plants).n- For watering ornamental plants (small beds, individual and potted plants).n- Cleaning gardening tools and garden furniture.
