Minimum flow valves are designed for use in recirculation systems of pumps supplying power boilers. They protect the pumps against hydraulic and thermal overload in case of low water consumption by the boiler, ensuring minimum flow in the bypass circuit of the pump (by-pass).
The valve type Z1B-M thanks to its construction, selection of materials and technology is a valve adapted to use in the most difficult working conditions, at a high pressure drop and risk of cavitation.
In the presented version, it can be used as a minimum flow valve in bypass systems (by-pass) of pumps supplying power boilers.
We can adjust the control valve to match your individual needs.
