{"title":"Pressure Limiting Valve","description":"\u003cp class=\"MsoNormal\" style=\"text-align: justify;\"\u003eThe PLV pressure limiting valve with 500kPa rating 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.  600kPa rating PLV is used on some jobs only when a high rating PTR valve is specified for the hot water services.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"text-align: justify;\"\u003eThe 350kPa PLV pressure limiting valve is usually used on caravans, trailers and tiny homes and for small applicances such as washing machines, dish washers and coffee machines. In caravan RV motor home applications, the PLV pressure limiting valves used must have an inbuilt check valve to prevent back flow from the on board water heater tanks, unless an external ball valve or check valve is used. \u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"text-align: justify;\"\u003eAll Plumbing Online carries brands including APO, AW, Reliance, AVG, Tomson, AW, Nefa and Reflex. 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.

In real world situations, the actual mains supply water pressure can fluctuate and vary greatly from locations to locations. This presents a unique challenge for caravans, as the outlet pressure can drop below 350kPa when at a caravan park with a low mains supply pressure. This a very wide spread complaint across the internet and the PLV pressure limiting valve is actually not faulty. The solution is to use a pressure reducing valve instead the pressure limiting valve, because the pressure reducing valve outlet pressure is adjustable on the spot to suit different inlet pressures as required.

This a very wide spread complaint across the internet and the PLV pressure limiting valve is actually not faulty. The solution is to use a pressure reducing valve instead the pressure limiting valve, because the pressure reducing valve outlet pressure is adjustable on the spot to suit different inlet pressures as required.

Without the check valve, the water heater can lose all its water and the heating element can burn out in a dry condition. If a caravan specific pressure limiting valve with an inbuilt check valve is required, this product is listed under the \"Caravan Plumbing\" category. This is a very common error by many customers, as both valves look very similar in appearances and both are called pressure limiting valves with the same 350kPa ratings. \u003c\/p\u003e\n\n  \u003cp style=\"margin: 10px 0 16px 0;\"\u003e\u003cstrong\u003e\u003cu\u003eTechnical Details\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\n  \u003cul style=\"margin-top: 0; margin-bottom: 16px; padding-left: 20px; list-style-type: disc;\"\u003e\n    \u003cli\u003eBrand: Reflex\u003c\/li\u003e\n    \u003cli\u003eModel: RPLV15I-350F\u003c\/li\u003e\n    \u003cli\u003eWatermark License Number: WMKA21795\u003c\/li\u003e\n    \u003cli\u003ePressure Outlet Rating: 350 kPa\u003c\/li\u003e\n    \u003cli\u003eTemperature Rating: 80°C\u003c\/li\u003e\n    \u003cli\u003eMax Inlet Pressure: 2000kPa\u003c\/li\u003e\n    \u003cli\u003eFlow Rate: 50L\/min at max allowable inlet pressure of 2000kPa \u003c\/li\u003e\n    \u003cli\u003eThread Size: 1\/2\" BSP (15mm) female FI thread\u003c\/li\u003e\n    \u003cli\u003eThread Size Physical Measurement: 20.995mm internal female thread diameter (refer to the BSP sizing chart in the photo gallery)\u003c\/li\u003e\n    \u003cli\u003eMaterial: Lead Free DR Brass\u003c\/li\u003e\n    \u003cli\u003eFeature: Include Insulation Jacket\u003c\/li\u003e\n    \u003cli\u003eIntended Use: caravan\/trailer\/tiny home water heaters; small appliances- coffee machines\/dish washers\/washing machines\/water fountains; Please check if an inbuilt check is required for your application\u003c\/li\u003e\n    \u003cli\u003eSKU: RPLV15I-350F\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cp style=\"margin: 10px 0 16px 0;\"\u003e\u003cstrong\u003e\u003cu\u003ePackage Contents\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\n  \u003cul style=\"margin-top: 0; margin-bottom: 0; padding-left: 20px; list-style-type: disc;\"\u003e\n    \u003cli\u003eReflex RPLV15I-350F Pressure Limiting Valve\u003c\/li\u003e\n    \u003cli\u003ePackage Weight: 450g\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n","brand":"Reflex","offers":[{"title":"Default Title","offer_id":55915327324328,"sku":"RPLV15I-350F","price":56.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0517\/2507\/4600\/files\/WhatsAppImage2026-08-26at16.32.49.png?v=1787804740"},{"product_id":"reflex-rplv15i-500f-15mm-500kpa-female-pressure-limiting-valve-with-insulation","title":"Reflex RPLV15I-500F 15mm 500kPa Female Pressure Limiting Valve with Insulation","description":"\u003cdiv style=\"font-family: Arial, sans-serif; font-size: 14px; line-height: 1.5; text-align: justify;\"\u003e\n  \u003cp style=\"margin: 0 0 16px 0;\"\u003e\u003cstrong\u003e\u003cu\u003eOverview\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\n  \u003cp style=\"margin: 0 0 16px 0;\"\u003eThe Reflex RPLV15I-500F15mm (1\/2\") 500kPa 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. An Insulation jacket is included in this listing for the Reflex pressure limiting valve for a professional look and to minimize the heat loss.\u003c\/p\u003e\n\n  \u003cp style=\"margin: 0 0 16px 0;\"\u003eThe Reflex PLV pressure limiting valve features the same BSP threads, fitments and similar physical sizes with many other valve manufacturers such as Reliance, AVG, Tomson, AW and Nefa.
