IVAR - Клапан, затвор, затвор для системы

Pressure reducing valves Pressure reducing valves are widely used in private installations to separate the system from public waterworks, characterised by a pressure too high and variable for direct use in household plants.‎ In fact the pressure reducing valve is capable of reducing and stabilising downstream pressure even with upstream pressure variations.‎ IVAR proposes two types of pressure reducing valves, with different operating principles.‎ The PRV line is characterised by diaphragm devices, an extremely sensitive and reactive element.‎ Their operation is based on the contrasting action of two forces exerted respectively by a spring and by a diaphragm on a compensated control valve.‎ PRV reducers are also equipped with outlet pressure indicator and filter which can be cleaned without being removed.‎ Available in sizes DN 15, 20, 25, 32 and 40, also in version with pipe unions.‎ The reducers of the RDP line are devices with a sensitive piston element, characterised by their stability even at high pressures.‎ Both PRV and RDP reducers have compensated seat, so that the outlet pressure from the reducer is stabilised at a set value regardless of the upstream pressure value.‎ Further info from manufacturer on PRV IVAR
