Pressure reducing valves for controlling incoming water pressure and protecting plumbing systems. These valves reduce and regulate supply pressure to a level appropriate for the installation.

The range includes piston and diaphragm pressure reducers, models with or without a pressure-gauge connection and different sizes and configurations. Products are available from Caleffi, Watts, OR and Tiemme, with spare parts and accessories for selected models.

Choose according to operating pressure, connections, dimensions and the technical requirements of the plumbing system.
