Overview

The Caleffi 533430H 10mm 3/8" micro pressure reduction valve is made in Italy and Australia Watermark approved. The Caleffi 533430H pressure reduction valve features a pressure adjustment range of 80-400kPa with a factory setting at 300kPa. This pressure reduction valve controls pressures accurately in specialized low flow applications such as water fountains, beverage dispensers and coffee machines. 

The "H" in the model’s name indicates this is a high temperature rated Caleffi pressure reduction valve at 80°C VS the standard Caleffi at just a rating of 40°C. The pressure reduction valve works by employing a membrane design with a stiff pre-loaded spring, which is adjustable to give the valve a pressure setting range. The pressure reduction valve can be used in places of pressure limitings valves in most plumbing applications, providing more pressure range flexibility and reliability. 

The pressure reduction 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.
