It consists of an expanding thermostatic element (PTC) which, upon receiving the 24 Vac command, causes a piston to extend and push down the valve stem, overcoming the return spring of the valve body. The actuator is made with double thermal insulation, a plastic cover, and a manual control knob for operation without power.\u003cbr\u003eThe STC45 product comes standard with an auxiliary microswitch whose function is typically to stop the circuit pump when the valve is closed.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":53962389258578,"sku":"STC45","price":69.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1088\/1708\/8850\/files\/stc25_1.jpg?v=1783590637","url":"https:\/\/intellisys-it.myshopify.com\/en\/products\/stc45","provider":"intellisys.it","version":"1.0","type":"link"}
