Overview

The AW (Austworld) Right Angle Pressure Reduction Free Lead Valve is Australia Watermark approved with BSP 20mm 3/4" female internal threads and a pressure adjustment range of 150-600kPa (500kPa factory set). Pressure reduction valves are commonly installed in residential plumbing operations such as after water meters or just before entering houses. These inline pressure reduction valves maintain a consistent water pressure supply, despite the fluctuations in the mains water supply pressure from the streets. 

The pressure reduction valves serve as a more reliable and versatile alternatives to traditional pressure limiting valves, when used in hot water services such as electric, heat pump, gas storage and solar hot water heaters. The pressure reduction 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 reduction valves can be used in such situations and offer a far better pressure control from our infield experiences over the years in our own pluming jobs in Brisbane. 

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.

So much fun
Size: Large Set of 3
The dog and my wife love these. The spines keep your the drool you have to touch to the minimum. Very durable for a dog that loves his toys and destroys them. Squeak is fun but got a little much. Just stabbed knife into the squeezer hole and silenced them right up - still kinda squeaks, just without all that high pitch goodness.

Great for playful dogs
Size: Medium Set of 6
These are great! I unfortunately had to return them because my dog is 45 pounds and they’re too big for her. She couldn’t carry them constantly in her mouth. But the quality, colors, squeak, and bouncy effects are perfect for playful dogs or simply getting your dog to play more. I’m going to see if they have smaller sizes available. Great value too!

Not for chewers
Size: Medium Set of 6
Not for chewers, but I bet non chewers would like the. Good quality, bounce, fun color and texture. Fun while it lasted, but didn't last long with my 2 year old pitbull. We've been trying to find the replacement to his durable spiky ball that went down a sewage drain. Right now the Chuck-Its are the ones that last (minus just one)

Almost Indestructible!
Size: Medium Set of 6
My dog LOVES these balls, and it's all about the squeaker (which my husband hates). The size is great and I don't worry about it getting lodged in her throat. They are very durable too. We had one lone ball for YEARS and I forgot it ever squeaked, but it was still in tact. I searched for a replacement because I was so impressed with it. Very happy to have found it. I just ordered some for my son's dog too. The squeaker may eventually come loose, but it's worth the money to buy again!
