Overview
Australian Valve Group (AVG) PTR25-400-LF 25mm (1") 400kPa PTR Pressure and Temperature Relief Valve (also known as TPR valve) is Australian Watermark approved and intended for commercial hot water service applications, with a high kilowatt rating of 132kW.
Pressure and temperature relief valves, known PTR valves are critical mechanical safety devices for all hot water services. The temperature sensing probe monitors the hot water service's temperatures. AVG PTR valve temperature probe is covered in a Teflon wrap to prevent any calcification build up overtime and to ensure long term accuracy. Inside the AVG PTR valve body, there is a piston mechanism that opens according to the pressure inside the water tank.
During the operation of the hot water services, the volume of the water will expand during heating cycles, as cold water heats up. This increased pressure can be dangerous if not regulated. The PTR valve regulates the pressure slowly dripping the water out of the tank in a controlled manner, usually via a discharge pipe into a drain or ground. Therefore, when the slow dripping is observed, it is just a perfectly normal PTR valve operation.
When there is a malfunction with the heating component or the thermostat in a hot water service, an uncontrolled heating can be extremely dangerous and explosions can occur catastrophically. PTR valve can detect this when the temperature and pressure exceed 99 deg or its preset pressure ratings. In this case, PTR valve will fully open and dump hundreds of liters of water to relieve the water heater tanks. The Kilowatt rating of the PTR valve refers to the rate that the PTR valve can dissipate this energy and this is regulated by Watermark and plumbing codes in Australia.
When a high kilowatt PTR valve rating is required in a commercial installation, a smaller sized 15mm or 20mm PTR valve must not be used as a cost cutting method for safety reasons.

Brilliant design and features.
Color: Black
Far better than yesteryears models. Very powerful with a lot of cork torque! The long USB cord is a HUGE plus to reach distant outlets. Charging base is another big plus. Don't forget to see the video of the girl who is promoting it but cannot figure out how to use it!! Hilarious.

Best Wine Opener We’ve Tried
Color: Black
My husband and I like to think of ourselves as wine connoisseurs, and over the years we’ve been through dozens of wine openers. So far, this one is our favorite. It’s pure magic—smooth, easy, and reliable every time. The charging base keeps everything organized. We’ve been using it for several months now without a single issue. It feels well-made and has definitely earned a permanent spot on our counter. It works so seamlessly that now we both want to open the wine.

Game Changer for Wine Lovers
Color: 8-in-1 Silver, Size: Rechargeable
Circle Joy Electric Wine Bottle Opener and I’m honestly really impressed.
Setup was super simple, and it works exactly as advertised—just place it on the bottle, press a button, and the cork comes out smoothly in seconds. No struggling, no broken corks, and no mess. It makes opening wine feel effortless and a lot more enjoyable.
I also love the sleek design—it looks modern and feels sturdy, not cheap. If you have the set with accessories, the extras like the foil cutter and pourer are a nice bonus and actually useful.
Overall, this is a great little gadget, especially if you open wine often or just want something convenient and easy to use. Definitely a solid buy or even a nice gift idea.
