An Integrated radiator balancing insert retains the radiator balancing setting when the TRV and Lock Shield valves are closed for cleaning and decorating. The valve can be mounted vertically or horizontally at either end of a radiator. To work correctly, the Valencia Traditional TRV should be installed to a two pipe heating system and also have a free flow of air around the head to sense temperature.\u003c\/p\u003e\n\u003cul type=\"disc\"\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman';\"\u003eBi-directional flow design\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman';\"\u003eCan be mounted vertically or horizontally\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman';\"\u003eIntegrated radiator balancing insert\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman';\"\u003eEasy grip TRV head with energy saving button that alerts user to economical setting for comfort\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman';\"\u003eLiquid sensor provides consistent and long-lasting performance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman';\"\u003eFrost setting\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman';\"\u003e6mm play on radiator tailpiece to allow for variation in radiator distance from the valve\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman';\"\u003eThe Valencia Classic Valve body will accept the evo home electronic radiator controller head\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pittway SARL","offers":[{"title":"Default Title","offer_id":53805483753818,"sku":"78081015","price":15.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/5354\/7866\/files\/BC_Upload_aff0cc9b-389d-4a31-bf4d-09929d9f7d4b.jpg?v=1773415559"},{"product_id":"15mm-angled-calypso-trv-l-s-pack","title":"Calypso 15mm Angled TRV \u0026 L\/S Pack","description":"\u003ch2 class=\"text-h1-mobile md:text-heading-xl font-bold text-primary mb-8\" style=\"text-align: center;\"\u003eTRV pack Calypso exact\u003c\/h2\u003e\n\u003cp class=\"mb-5 md:mb-6 lg:mb-7\"\u003e\u003cspan\u003eBi-directional thermostatic radiator valve with stepless precision presetting, head and lockshield.\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"mb-5 md:mb-6 lg:mb-7\"\u003eThe HEIMEIER TRV pack, consists of a Calypso TRV body, D-U head and lockshield.
