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 golf shirt!
Size: Small, Color: White/Light Blue Stripe
My son loves this shirt! It has silky smooth wrinkle-fabric and is nice and cool on the golf course. It is true to size, hangs well (no clinging) and allows full range of movement. It washes great! I wash and dry in the machine and stains come right out.

Beautiful colors, nice golf shirt
Size: XX-Large, Color: Aqua Blue Stripe
I always read reviews before I purchase and this golf shirt had positive ones. I ordered one so I could see the fit (true to size), and see how it laundered. Both are a thumbs up from me. Beautiful vibrant color, at a price comparable or less than what you might find in store. The SPF protection is a plus. I will be ordering more.

Golf shirt
Size: Large, Color: Aqua Blue Stripe
I like the shirt is comfortable, but I thought the ad said three of them and Allie got one. Haven’t looked to see how much I paid for it.

I like these fleece-lined pants
Color: Black, Size: 32W x 32L
For these specific pants, the 32" inseam is accurate and fits as expected. The fleece lining was great in high 40's and did not feel too warm when the temp climbed into the 60's. I was impressed enough to buy a second pair. They appear to be well made and look great.

Perfect. Warmth without bulk
Color: Grey, Size: 34W x 30L
Perfect thickness and insulation level. Warmth without bulk. Stylish and do a good job disguising what they are. Cut is similar to "regular" or "straight" cut jeans. Will be ordering other colors...
