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.

Great shirt, a bit large in arms
Color: A - Moon Gray, Size: Medium
I really like the cut and texture of the shirt. The only thing I would say is it is loose in the arms unless you’re a body builder. My arms are toned, muscular, but more lean than thick, so if you like a snug sleeve this is probably not for you. I’m 5’9” 180bs for reference and wear a medium.

Check the size chart and reviews!
Color: Black, Size: 3X-Large, Color: Black, Size: 3X-Large
Bought this for my husband and if i didnt check the reviews I would ordered it too small. He normally wears a XL in T-shirts but he has very large arms so the 3XL in this fits him comfortably. The material is a bit stretchy so he could have probably taken the 2XL but I am satisfied with how the 3XL looks on him. He looks so good!

Size discrepancy
Color: Wine Red, Size: Small
I like the look and feel of this shirt, but I originally bought a medium and it was too big, so I bought a small. Both shirts are the exact same size. It is labeled on the collar as a different size, but it's the same. If anything the small is slightly larger

Happy with my purchase
Color: Black, Size: X-Large
The material is good quality and it did great in the gentle cycle of my washing machine. I hung it to dry, no dryer. Looks great.
