Overview

AW WSP40LF Solar Rated Non Return One Way Check Valve is spring loaded and designed to prevent the high-temperature backflow from the roof collectors present in solar hot water systems. In order to survive this high temperature working environment, the AW check valves are constructed with lead free DR brass body, silicone seals and high temperature rated full brass internals.

During the operation of solar hot water systems in summer, a stagnation condition can be created as the storage water tank reaches its maximum top out temperature usually around 60-70 degrees. In such stagnant conditions, the solar pump will stop water circulation and the solar roof collectors can reach 180°C in flat plate panels and 200+°C in evacuated tubes. This super heated water remains in liquid form due to the pressure in the solar hot water system and pushes down back to the water tank creating the backflow. This back flow can cause damages to the water pumps, flow meter and other components if not prevented. A standard check valve that is not solar rated will melt over time with the usual plastic internal components. A swing type check valve would create excessive flow resistance and poor seal. The AW WSP40LF spring loaded solar rated check valve is perfect in such installations, offering minimal pressure drop during water pump operation and long lasting seal even in continuous high temperature environment.

The AW solar check valves can be installed in either vertical or horizontal orientations and is WaterMark Approved for compliance in Australia. The solar rated check valves can be also used in low temperature rating steam applications.

Absolute horrible quality
Color: Black, Size: Medium
Do not purchase this track suit even if its on sale. The fabric material is so cheap, it feels like a tacky uncomfortable plastic bottle that's been stretched out over your body. The stitching feels very off and the thickness is somehow too bulky and looks baggy and at the same time feels too tight. Do yourself a favor and avoid, I'm returning this product.

Comfortable and Slick
Color: Grey, Size: X-Large
The track suit has been my tai chi workout go to. The fabric is light and non constrictive so I can move effortlessly. The material is soft and feels nice. Does not get too wrinkly when folded. The color is nice. Top fits nicely, true to size (6’ and 190 lbs). The bottoms are a bit baggy though but my bum is flat, so can complain. I think next time I would purchase separate pieces and go with XL top and L bottom. Perhaps mix the colors too so I don’t look like an orderly on break! I will caution on wearing this type of material over spandex or slippery underwear. I was walking my three large dogs and they got tangled and the leash snagged and pulled down my pants exposing my underwear to the world. Luckily, I had clean undies with no rips, although no one was around the trail we were on! This is my first Coofandy purchase and I would definitely purchase again.
