It features the same reliable PTC wax element and first-open function as the 2-wire version, but adds a micro-switch that provides a volt-free signal when the valve is fully open. This makes it ideal for systems with wiring centres that require valve status confirmation or for integration with advanced controls and BMS.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Wire Configuration:\u003c\/strong\u003e Live, Neutral + 2-wire volt-free end switch for open\/closed feedback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNormally Closed (NC):\u003c\/strong\u003e Opens when powered.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirst-Open function:\u003c\/strong\u003e Automatically opens during commissioning for easy filling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVisual status indicator:\u003c\/strong\u003e Clear all-round display shows power and valve position.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM30 x 1.5 thread:\u003c\/strong\u003e Direct fit for all Polypipe manifolds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow power consumption:\u003c\/strong\u003e 1 W operating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP54 rated:\u003c\/strong\u003e Protected against dust and water splashes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSnap-on installation:\u003c\/strong\u003e Quick and secure 360° positioning.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e PB00402 – Polyplumb 4-Wire Valve Actuator.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 230 V AC, 50\/60 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower consumption:\u003c\/strong\u003e 1 W (operating).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke:\u003c\/strong\u003e 4.0 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuating force:\u003c\/strong\u003e 100 N (±10%).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening\/closing time:\u003c\/strong\u003e Approx. 3.5 minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread connection:\u003c\/strong\u003e M30 x 1.5.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection rating:\u003c\/strong\u003e IP54.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection class:\u003c\/strong\u003e Class II.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd switch:\u003c\/strong\u003e Volt-free (SPST) – rated 5 A @ 250 V AC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable length:\u003c\/strong\u003e 1 metre (4-core pre-wired).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDimensions \u0026amp; Weights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 55 mm (approx.).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 45 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 110 g (including cable).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSystem \u0026amp; Application Notes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSpecifically designed for Polypipe underfloor heating manifolds.\u003c\/li\u003e\n\u003cli\u003eIdeal when valve status feedback is required (e.g. wiring centres with LED indicators or BMS).\u003c\/li\u003e\n\u003cli\u003eCompatible with all standard M30 x 1.5 manifold valves.\u003c\/li\u003e\n\u003cli\u003eWorks with Polypipe 230V room thermostats and wiring centres.\u003c\/li\u003e\n\u003cli\u003eProfessional installation recommended.\u003c\/li\u003e\n\u003cli\u003e5-year manufacturer warranty (subject to terms).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Polypipe","offers":[{"title":"Default Title","offer_id":63454449008989,"sku":"PB00402","price":53.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/2051\/3629\/files\/polypipe-valve-actuator-pb00401.jpg?v=1771243605","url":"https:\/\/qualityheating.co.uk\/products\/polypipe-pb00402-polyplumb-4-wire-ufh-valve-actuator-230v-normally-closed-with-end-switch-feedback-for-underfloor-heating-manifolds","provider":"AIZO Quality Heating","version":"1.0","type":"link"}
