The temperature sensing probe monitors the hot water service's temperatures.

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.

In this case, PTR valve will fully open and dump hundreds of liters of water to relieve the water heater tanks.

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. \u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eWhen 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. \u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003ch4\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eTechnical Details\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Australian Valve Group (AVG)\u003c\/li\u003e\n\u003cli\u003eModel: PTR25-850-LF\u003c\/li\u003e\n\u003cli\u003eWatermark License Number: 2639\u003c\/li\u003e\n\u003cli\u003eExpansion Rating: 132kW \u003c\/li\u003e\n\u003cli\u003ePressure Rating: 850 kPa\u003c\/li\u003e\n\u003cli\u003eTemperature Rating: 99°C\u003c\/li\u003e\n\u003cli\u003eThread Size: 1\" BSP (25mm) Male MI thread and female FI thread\u003c\/li\u003e\n\u003cli\u003eThread Size Physical Measurements: 33.249mm external male and internal female thread diameter (refer to the BSP sizing chart in the photo gallery)\u003c\/li\u003e\n\u003cli\u003eInsulation Jacket Included \u003c\/li\u003e\n\u003cli\u003eMaterial: DR Brass Body; Stainless Steel Pressure Spring; Copper\/Stainless Steel Element; Silicon Seals.\u003c\/li\u003e\n\u003cli\u003eIntended Use: For commercial hot water service applications where high Kilowatt rating is required for the PTR valves.\u003c\/li\u003e\n\u003cli\u003eSKU: AVG-PTR25-850-LF\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003ePackage Contents\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eAVG PTR25-850-LF kPa PTR Valve 25mm (1\") 850kPa \u003c\/li\u003e\n\u003cli\u003ePackage Weight: 900g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cb\u003e\u003cu\u003e\u003cspan style=\"font-size: large;\" size=\"4\"\u003e\u003c\/span\u003e\u003c\/u\u003e\u003c\/b\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"AVG","offers":[{"title":"Default Title","offer_id":43365963333800,"sku":"AVG-PTR25-850-LF","price":255.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0517\/2507\/4600\/files\/Image_20250724105701.jpg?v=1753320091"},{"product_id":"apo-15mm-850kpa-ptr-tpr-pressure-temperature-relief-valve","title":"APO 15mm 850kPa PTR \/ TPR Pressure Temperature Relief Valve","description":"\u003ch4 data-mce-fragment=\"1\"\u003e\n\u003cspan data-mce-fragment=\"1\" style=\"text-decoration: underline;\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eOverview\u003c\/strong\u003e\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/h4\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe APO PTR15\/850 15mm (1\/2\") 850kPa PTR Pressure and Temperature Relief Valve, also known as TPR valve is used to regulate the water pressure inside hot water services, including h\u003cspan data-mce-fragment=\"1\"\u003eeat 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. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eThe APO PTR valve features the same threads, fitments and similar physical sizes with many other PTR valve manufacturer brands such as Reliance' HT55, AVG, Tomson, Nefa and Reflex.

A larger PTR valve will usually have a larger KW rating and this KW rating is specified by local plumbing rules, especially in large commercial hot water systems.\u003c\/p\u003e\n\u003cp\u003eA functioning PTR valve is a requirement by law in Australia for safety as per explained above. A typical sign for a faulty PTR valve is when there is a large amount of water leakage in a stream, rather than a controlled dripping. The worn out or leaking PTR valve must be replaced immediately. \u003c\/p\u003e\n\u003ch4\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eTechnical Details\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Reflex\u003c\/li\u003e\n\u003cli\u003eModel: RPTRE15I-1400\u003c\/li\u003e\n\u003cli\u003eWatermark License Number: WMKA21795\u003c\/li\u003e\n\u003cli\u003eExpansion Rating: 10 kW \u003c\/li\u003e\n\u003cli\u003ePressure Rating: 1400 kPa\u003c\/li\u003e\n\u003cli\u003eTemperature Rating: 99°C\u003c\/li\u003e\n\u003cli\u003eThread Size: 1\/2\" BSP (15mm) Male MI thread and female FI thread\u003c\/li\u003e\n\u003cli\u003eThread Size Physical Measurements: 20.995mm external male and internal female thread diameter (refer to the BSP sizing chart in the photo gallery)\u003c\/li\u003e\n\u003cli\u003eInsulation Jackets\u003c\/li\u003e\n\u003cli\u003eMaterial: DR Brass\u003c\/li\u003e\n\u003cli\u003eIntended Use: Electric tanks, solar tanks, gas storage tanks and heat pumps\u003c\/li\u003e\n\u003cli\u003eSKU: RPTRE15I-1400\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"padding-left: 30px;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch4\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003ePackage Contents\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eReflex RPTRE15I-1400 15mm 1400kPa PTR Valve\u003c\/li\u003e\n\u003cli\u003ePackage Weight: 360g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Reflex","offers":[{"title":"Default Title","offer_id":53219858514088,"sku":"RPTRE15I-1400","price":57.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0517\/2507\/4600\/files\/Image_20250716162421.jpg?v=1752648344"},{"product_id":"avg-universal-15-20mm-ptr-ecv-valve-insulation-jacket-for-avg-reliance-tomson-nefa","title":"AVG Universal 15\/20mm PTR ECV Valve Insulation Jacket for AVG Reliance Tomson Nefa","description":"\u003ch4 data-mce-fragment=\"1\"\u003e\n\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eOverview\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/h4\u003e\n\u003cp\u003e\u003cspan face=\"-apple-system, BlinkMacSystemFont, San Francisco, Segoe UI, Roboto, Helvetica Neue, sans-serif\" color=\"#1f2124\" style=\"color: #1f2124; font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif;\"\u003e\u003cspan\u003eAVG universal PTR ECV valve insulation jacket is compatible with PTR pressure temperature relief valves and ECV expansion control valves from all mainstream manufacturers such\u003c\/span\u003e\u003c\/span\u003e\u003cspan face=\"-apple-system, BlinkMacSystemFont, San Francisco, Segoe UI, Roboto, Helvetica Neue, sans-serif\" color=\"#1f2124\" style=\"color: #1f2124; font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif;\"\u003e\u003cspan\u003e as AVG, Reliance Tomson H55 H50, Nefa, Reflex, Edison and APO in both 15mm \u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e½\" \u003c\/span\u003e\u003cspan face=\"-apple-system, BlinkMacSystemFont, San Francisco, Segoe UI, Roboto, Helvetica Neue, sans-serif\" color=\"#1f2124\" style=\"color: #1f2124; font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif;\"\u003e\u003cspan\u003eand 20mm \u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e¾\" sizes. \u003c\/span\u003e\u003cspan face=\"-apple-system, BlinkMacSystemFont, San Francisco, Segoe UI, Roboto, Helvetica Neue, sans-serif\" color=\"#1f2124\" style=\"color: #1f2124; font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif;\"\u003e\u003cspan\u003eThese PTR and ECV valves are fitted to heat pumps, electric, gas storage and solar water heaters across brands including Rheem, Rinnai, Dux, Chromagen, Solarhart, Vulcan, Therman, Apricus and Solahart.
