Overview

The AW PLV20C-500 20mm (3/4") 500kPa male compression PLV pressure limiting valve is commonly used to regulate the supply cold water pressure to hot water services including heat pumps, electric, gas storage and solar water heaters across all mainstream brands in Australia such as Rheem, Vulcan, Rinnal, Dux, Aquamax, Thermann, Apricus and Solahart. 

The AW PLV pressure limiting valve features the same threads, fitments and similar physical sizes with many other valve manufacturers such as Reliance, AVG, Tomson, Nefa and Reflex. This makes the AW PLV pressure limiting valve a perfect direct replacement to an existing valve with no plumbing pipe modifications required. When the compression nuts and the copper olives are removed, this PLV pressure limiting valve can be used as male threaded valves.

The PLV pressure limiting valves usually come in 350, 500 and 600kPa ratings under Australian Watermark standard regulations. Each pressure specification is used on specific plumbing applications, depending the pressure rating requirement of the appliances. The PLV pressure limiting valve regulates the inlet water pressure by employing a sliding piston design internally and creates a pressure drop as the water passes through the valve. This piston design is directional and therefore there is an arrow on each pressure limiting valve body indicating the water flow orientation.  

Engineer's Notes

When a PLV pressure limiting valve fails, it is usually caused by the corrosion and debris clogging-up inside the valve body, preventing the piston's sliding actions over its usage life spans. In most cases, the water pressure and flow rate can drop significantly causing an unsatisfying user experience. In less common scenarios, the opposite can also happen and the pressure limiting valve may lose its pressure limiting ability, potentially blowing up appliances with over pressures. 

A PLV pressure limiting valve can only limit the dynamic pressure of the passing inlet water. The valve can not regulate a static pressure increase inside a water heater when the water heats up and expands, where PTR and ECV valves must be used instead for the pressure relief.

The 500kPa is a nominal outlet pressure rating under Australian Watermark Standard testing condition with a set inlet pressure. In real world situations, the actual mains supply water pressure can fluctuate and vary greatly from locations to locations. This presents a challenge for many hot water heater installations, especially when the street's mains pressure is too high. In this scenario, the PLV pressure limiting valve may fail to limit the inlet pressure below the hot water tank's pressure rating requirement. The PTR and ECV valves of the hot water service can leak excessively or even in a continuous stream as consequences. In such situations, pressure reducing valves can be used in the places of the pressure limiting valves to address this problem. 

The compression nuts at the ends of the PLV pressure limiting valve are used to connect to the Australian standard 20mm 3/4"sized copper pipes. The olives inside bite into the copper pipes to form a water tight seal when the cone nuts are tightened and no plumbing tapes should be used for compression type connections to maximize the biting force. 

When the compression end nuts and olives are removed, the the male threads are exposed underneath. The PLV pressure limiting valve can be used as a threaded valve to screw into fittings and other valves. During all threaded connections, plumbing tapes must be used between the male and female threads.

Cat approves, easy to use, comfortable to grip, sturdy.
Color: Microbrush Kit, Color: Microbrush Kit
My cat seems to love it so that's a automatic win! I was a little unsure about using a long handled toothbrush, I thought it would be more difficult to use but turns out its actually easier than the little finger brushes. The heads on the toothbrushes can be swapped, making it so that you dont have to buy a whole new one. It's been a few months since I bought it and its holding up well, no major wear on it aside from some gnaw marks from my Chonk chewing on it. Fits nicely in my hand and the brush head isn't too big for my cats tiny faces & teeth. I'd recommend it so far and I'm going to keep on with this brush instead of trying a new product every time.

its packaged nice and it is a smaller product to fit in kitty mouths but still not great.
Color: Microbrush Kit
it's a nice product but still doesn't make my cats any easier to brush. Nor does it seem enjoyable. I enjoy brushing my teeth and I want them too also. I believe cats life would be so much longer if we brushed their teeth. Think about how early our ancestors died before proper dental care.

Great Grip and Perfect for Reaching Back Teeth
Color: Microbrush Kit
Summary: A thoughtfully designed toothbrush that makes feline dental care much easier. Pros: • Comfortable, secure grip that makes brushing feel more controlled • Great design for reaching back teeth, which can be the hardest area to clean • My cats don’t mind getting their teeth brushed with this, which is a huge plus • Removable, replaceable brush head, so you don’t have to buy a whole new tool each time Overall: If you’re looking for an effective way to brush your cat’s teeth, this is a very well thought-out design. It worked great with my cats, and I’m genuinely grateful for how much easier it has made our brushing routine.

Good deal
Scent: North Bondi, Size: 1.7 Fl Oz (Pack of 1)
Good quality for the price. Smell of clean sheets (that is not a very safe blind buy considering that smells of cleanness are very particular), also has a strong note of violet flowers, consider it while buying. It is also pretty long-lasting for these types of perfumes. Overall, I’m happy with a purchase and a scent, what surprised me the most is the magnetic cap.

Amazing scent!
Scent: North Bondi, Size: 1.7 Fl Oz (Pack of 1)
AMAZING smell, and it lasts so long too! I did one spray and could smell it for the rest of the day. The perfect scent for someone who doesn’t like overpowering, but also wants a clean scent. I am OBSESSED.
