• Water pressure reducing valves and check valves are part of the group of safety and protection valves used in making water supply and heating systems. Water pressure reducing valves are designed to reduce the pressure in domestic and industrial water supply systems. The reducing valve maintains a constant set outlet pressure (controllable) in dynamic and static modes irrespective of changes in the inlet pressure. Installing this product helps to avoid damage caused by excess pressure and hydraulic impacts, as well as to reduce water consumption.

    PROFACTOR® offers two types of pressure reducing valves which are different in design: the diaphragm and the valve-piston type. The valve-piston reducing valves have the outlet pressure factory setting of 2.5 bar, the diaphragm reducing valves - of 3 bar. The setting may be changed without the need to dismantle the device by setting the necessary outlet pressure in the range of 1-4 bar for valve-piston reducing valves and 1-6 for diaphragm reducing valves.

It is intended for control of the heat carrier flow in the heating systems while preserving the continuous rate of the flow. The required system temperature is achieved by feeding up of the necessary amount of liquid from the return pipe of the boiler.

It is applied if necessary to increase the temperature of the heat carrier supplied to the boiler from the return pipeline (e.g.) for solid-fuel boilers.
The valve operates according to the double bypass principle allowing to a portion of the hot heat carrier supplied from the boiler to be immediately admixed to the return pipeline with bypassing the heat transfer circuits. This decreases the risk of low-temperature corrosion of the boiler thus extending its service life.
Valves are compatible with servomotors: ELODRIVE ST10; STM10; Barberi P27T, M03, M04
