{"product_id":"mva23","title":"MVA23","description":"\u003cp style=\"text-align: justify;\"\u003eElectrothermal actuator for zone valves and terminal units, without cable, connectable with CONTROLLI globe valves series \u003cstrong\u003eVZS\u003c\/strong\u003e 2-way, \u003cstrong\u003eVMZ\u003c\/strong\u003e 3-way, and \u003cstrong\u003eVTZ\u003c\/strong\u003e 3-way 4-port. It consists of an expanding thermostatic element that, upon receiving a 230 Vac command, causes a piston to extend and push down the valve stem, overcoming the return spring of the valve body itself.\u003cbr\u003e\u003cbr\u003eThe difference between MVA21 and MVA23 is that MVA21 includes a cable, so MVA23 can be used as a replacement for MVA21, keeping the existing cable. The \u003cstrong\u003eMVA23\u003c\/strong\u003e product can also be used to replace previous \u003cstrong\u003eZ600\u003c\/strong\u003e and \u003cstrong\u003eZ200\u003c\/strong\u003e series actuators, provided that the valve on which the replacement is to be made has a brass-colored return spring. It also finds application as a replacement for the thermal actuator heads of \u003cstrong\u003eRBM\u003c\/strong\u003e (R.B.M. S.p.A.) zone valves.\u003cbr\u003e\u003cbr\u003eThe D41 auxiliary microswitch accessory can be ordered separately; its function is usually to stop the circuit pump when the valve is closed.\u003c\/p\u003e","brand":"iSMA Controlli","offers":[{"title":"Default Title","offer_id":53962357178706,"sku":"MVA23","price":55.5,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1088\/1708\/8850\/files\/mva23_view1_web_4.jpg?v=1783590618","url":"https:\/\/intellisys-it.myshopify.com\/en\/products\/mva23","provider":"intellisys.it","version":"1.0","type":"link"}
