Pressure Reduction Valves are fitted in water systems to moderate and stabilise mains water pressure, which is at times too high for domestic appliances. The valves are pre-set at 500KPa which is the most widely used setting for domestic appliances. However the pressure reduction valves can be easily adjusted to suit your needs from a range of 150KPa to 600KPa.
