It uses a PTC resistor-heated wax element and compression spring for reliable operation. Normally closed, it opens when powered and features a first-open function for construction phase use. The actuator includes a built-in indicator for power and valve status, ensuring easy monitoring and maintenance-free performance.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNormally closed (NC):\u003c\/strong\u003e Opens when powered, with first-open function for initial use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow power consumption:\u003c\/strong\u003e 1 W operating power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSnap-on installation:\u003c\/strong\u003e Simple 360° positioning with valve adapter system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction indicator:\u003c\/strong\u003e All-around display shows power on\/off and valve open\/closed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh safety:\u003c\/strong\u003e 100% protection against leaky valves, surge protection, and TUV certified.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact and quiet:\u003c\/strong\u003e Minimal operational noise and maintenance-free.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP54 rated:\u003c\/strong\u003e Suitable for various environments.\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 PB00401 – UFCH Valve Actuator.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating voltage:\u003c\/strong\u003e 230 V AC (±10%) 50\/60 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum inrush current:\u003c\/strong\u003e \u0026lt; 550 mA during 100 ms max.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating power:\u003c\/strong\u003e 1 W.\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 ~3.5 minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid temperature:\u003c\/strong\u003e 0 to +100°C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient temperature:\u003c\/strong\u003e 0°C to +60°C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage temperature:\u003c\/strong\u003e -25°C to +60°C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDegree of protection:\u003c\/strong\u003e IP54.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection class:\u003c\/strong\u003e II.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCE conformity:\u003c\/strong\u003e EN 60730.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurge protection:\u003c\/strong\u003e EN 60730-1, 2.5 kV.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing material:\u003c\/strong\u003e Polyamide, light grey (RAL 7035).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnecting cable:\u003c\/strong\u003e 2 x 0.75 mm² PVC, light grey, 1 meter.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDimensions \u0026amp; Weights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 100 g with connecting cable.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSystem \u0026amp; Application Notes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIdeal for Polypipe underfloor heating manifolds to control individual circuits based on thermostat demands.\u003c\/li\u003e\n\u003cli\u003eCompatible with valve-adapter-system for simple integration.\u003c\/li\u003e\n\u003cli\u003eInstallation: Snap-on to adaptor after screwing adaptor onto valve; connect to 230V supply; audible click confirms secure fit.\u003c\/li\u003e\n\u003cli\u003eUse recommended cables: NYM 1.5 mm² or NYIF 1.5 mm².\u003c\/li\u003e\n\u003cli\u003eProfessional installation recommended; TUV certified for safety.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Polypipe","offers":[{"title":"Default Title","offer_id":63419900199261,"sku":"PB00401","price":29.95,"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-230v-normally-closed-thermal-actuator-for-underfloor-heating-manifolds-pb00401","provider":"AIZO Quality Heating","version":"1.0","type":"link"}
