Part of Evolve’s practical and value-driven Contract range, this straight TRV helps optimise heating performance while maintaining a comfortable living environment.\n\nThis valve allows you to set a desired room temperature, and it automatically adjusts the flow of hot water into the radiator based on that setting. As the room reaches your preferred temperature, the valve reduces the water flow, helping to prevent overheating. This not only maintains consistent comfort but also reduces unnecessary energy consumption—an ideal choice for those looking to improve energy efficiency at home or in commercial settings.\n\nWith its chrome and white finish, the valve blends neatly into modern interiors, while its straight design makes it perfect for installations where pipework runs vertically up to the radiator.\n\n\u003ch3\u003eKey Technical Specifications\u003c\/h3\u003e\nConnection Size: 15mm\n\nOrientation: Straight\n\nFinish: Chrome\/White\n\nTemperature Adjustment Range: 0°C to 28°C\n\nFrost Protection Setting: Activates at 7°C to protect against pipe freezing\n\nMaximum Working Pressure: 10 bar\n\nMaximum Differential Pressure: 1 bar\n\nMaximum Water Temperature: 100°C\n\nMaximum Ambient Temperature: 50°C\n\n?? Note: The TRV can be used as a reverse flow valve only if the system’s differential pressure does not exceed 0.25 bar.\n\n\u003ch3\u003eBenefits of the Evolve Straight TRV\u003c\/h3\u003e\n? Energy Efficiency: By adjusting water flow automatically, this TRV helps lower heating bills.\n\n? Consistent Comfort: Maintains steady room temperature, improving overall comfort.\n\n? Straight Pipe Compatibility: Ideal for radiator setups with vertical pipe entries.\n\n? Frost Protection: Keeps pipes safe in winter conditions thanks to the built-in frost setting.\n\n? Simple Installation: Designed for quick and easy fitting with standard 15mm pipework.\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003eWhat’s the difference between a straight and angled TRV?\u003c\/h4\u003e A straight TRV is designed for pipework that enters the radiator from directly below or above, running in a straight line. An angled TRV, on the other hand, is used when the pipework enters from the wall or at a 90-degree angle. \u003ch4\u003eIs this TRV suitable for combi boiler systems?\u003c\/h4\u003e Yes, it is compatible with most sealed central heating systems, including those connected to combi boilers. Just ensure that your system pressure and temperature are within the TRV’s limits. \u003ch4\u003eHow does the frost setting work?\u003c\/h4\u003e The frost protection feature is automatically triggered when the room temperature drops to around 7°C. This keeps a small amount of water flowing through the radiator, helping prevent frozen pipes in colder conditions.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/plumbing-supplies\"\u003eplumbing supplies\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/valves\"\u003evalves\u003c\/a\u003e available online.\u003c\/p\u003e","brand":"Evolve","offers":[{"title":"Default Title","offer_id":50802407735638,"sku":"147219","price":1.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/evolve-contract-15-mm-straight-chromewhite-trv-4542782.jpg?v=1772662216","url":"https:\/\/jjbuildingmaterials.co.uk\/products\/evolve-contract-15-mm-straight-chrome-white-trv","provider":"JJ Building Materials","version":"1.0","type":"link"}
