    Overview

    The Caleffi 533545 15mm 1/2" inline pressure reducing valve is made in Italy and Australia Watermark approved. The Caleffi 533545 pressure reducing valve features a pressure adjustment range of 100-600kPa with a factory setting at 500kPa. Caleffi is the one of only a rare few manufacturers in Australia offering a pressure reducing valve that can adjust to a pressure setting  as low as 100kPa, which is required for specialized applications.
    The pressure reducing valves are commonly installed in residential plumbing works such as after water meters or just before entering houses. The pressure reducing valves can ensure a stable water supply pressure supply, despite the fluctuations in the mains water supply pressure from the streets. 
    The pressure reducing valves can serve as a more reliable and versatile alternatives to more traditional pressure limiting valves, when used in hot water services such as electric, heat pump, gas storage and solar hot water heaters. The pressure reducing valve employs a membrane design inside with a stiff pre-loaded adjustable spring, opposed to a sliding piston mechanism found in a pressure limiting valve which often causes failures from clogging up. 
    In real world installations, it is sometimes found that pressure limiting valves cannot limit pressures sufficiently in places where unusually high street mains pressures are present. This can cause troubles with ECV and PTR valves leaking on hot water services. The pressure reducing valves can be used in such situations and offer a far better pressure control from our in field experiences over the years in our own plumbing jobs in Brisbane. 
    The pressure reducing valve comes with a BSP 6mm test plug inbuilt, where an optional pressure gauge can be inserted for pressure measurement at the outlet. The optional pressure gauge is shown in the photo gallery and can be bought for extra. It must be noted that the pressure gauge is only intended to be used as a measurement tool and must be removed after use, as it could rust inside out if left in a wet environment for prolonged periods of time.
