As the actuator rotates, a spring inside is wound up, and the motor then stalls out, holding the valve open. When power is removed from the actuator, the energy in the coiled spring is released, closing the valve and shutting down the actuator.\u003c\/p\u003e\u003cul style='box-sizing: border-box; margin: 0px 0px 1.5rem; padding: 0px; list-style-position: inside; color: rgb(40, 40, 40); font-family: \"Source Sans Pro\", Arial, Helvetica, sans-serif; font-size: 16px;'\u003e\u003cli style=\"box-sizing: border-box; margin: 0px; padding: 0px;\"\u003eSuitable to operate 2 port ON\/OFF valves\u003c\/li\u003e\u003c\/ul\u003e","brand":"Sunvic","offers":[{"title":"Default Title","offer_id":52016575840535,"sku":"306611189891","price":199.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0776\/7828\/0983\/files\/57_fcac0272-b803-437c-9b61-9fbd3c7dcedf.png?v=1770370313","url":"https:\/\/swift-spares.co.uk\/products\/sunvic-sz2355-2-port-spring-return-actuator-6-wires-normally-open","provider":"Swift Spares Ltd","version":"1.0","type":"link"}
