Overview
Australian Valve Group (AVG) PTR25-700-LF 25mm (1") 700kPa 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.

Cool and moist
Size: 1 Count (Pack of 2)
I had to get away from scented products and this one was cleared by my ACDS app. It is small, not resealable, but easy to use, and cleans well, the wipes are sturdy, and just wet enough to clean without needing extra drying. These are travel size and have to be kept in a zip lock after opening.

Good choice for sensitive skin
Size: 25 Count (Pack of 1)
I purchased this in preparation for a trip. I wanted to be able to clean my face while on a flight but have super sensitive skin so normal makeup wipes burn and cause a lot of irritation. These are very similar to baby wipes. They have virtually no scent and work relatively well in getting off sunscreen. I haven tried with makeup yet so I can’t speak on that. I used about 2 or 3 and my face didn’t burn at all. I think it’s a good choice for those who want the convenience of a makeup wipe but can’t use regular ones.

Very gentle, yet effective
Size: 25 Count (Pack of 1)
These are a great bang for your buck! My daughter struggles with her sensitive skin. These make up wipes are so soft and feels like a gentle clothe. No obnoxious smells, and resealable. Perfect for traveling. Her skin feels great after wiping off the most stubborn water proof make up. The price makes it a no brainer!
