Overview

The AW PLV15C-350 15mm (1/2") 350kPa 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 350kPa 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 15mm 1/2"sized copper pipes, which are most common in the residential plumbing. 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.

Nice
Style: Milky Toner
I have tried the regular version of this toner years ago and I loved it. It was one of the few products I have used that I could actually notice a visible difference after using. I liked the texture of this one and was excited to try it. I was using Glycolic acid prior to ordering this and wasn't thrilled with my results. This one was nice because it felt nice on my skin and there was definitely no burning even if I use it on an active or open acne spot. There's no scent and the ingredients are fairly good. However, I would be lying if I said I have noticed any visible signs of it working.

Sensitive skin friendly
Style: Milky Toner, Style: Milky Toner
As someone with very sensitive and acne prone skin, I absolutely love this toner. It doesn’t cause any irritation or any noticeable disruption to my skin barrier. It’s just a little drink of hydration for my skin and that’s really it! The ingredients are super conscious and clean too

The glow is gorgeous and not over the top
Color: 100ml #03-Bronze Gold
If you want that golden hour shimmer without looking like a disco ball, this body oil is it. I got it for a beach trip and ended up using it almost every day since. It gives your skin the prettiest bronzy glow with just enough sparkle to catch the light without feeling glittery or sticky. It blends in super smoothly and actually makes my skin look healthier. I’ve used it on my collarbones, shoulders, and even mixed a tiny bit into my foundation when I want that sun-kissed look. The scent is light and pretty too, not overpowering at all. A little goes a long way, so the bottle lasts. Plus it doesn’t transfer all over my clothes, which is a major win. If you love that radiant summer look or want to fake a tan without streaks, you’ll love this. Would totally buy again. Feels like a mini vacation in a bottle.
