The YZNG TRONG electric valve actuator automates on\/off operation of quarter-turn ball valves in 3\/8\u2033 to 1-1\/4\u2033. It accepts AC 110V, 220V or 380V (single phase), or DC 24V or 48V. When mains power is lost, the built-in lithium battery drives the valve to the fully closed position<\/strong> \u2014 the line shuts, without an air supply, a spring, or an external UPS.<\/p>\n

A full charge is good for approximately 5,000 operations<\/strong>, and full travel takes 3 seconds<\/strong>, open to close. An LCD on the actuator shows the battery level, and wiring runs through an aviation plug connector, so a technician can connect or disconnect without opening the cover.<\/p>\n

What Happens When the Power Fails<\/h2>\n

This is the question that decides the purchase, so here is the direct answer: the valve closes.<\/strong> The lithium battery inside the actuator holds enough charge for approximately 5,000 operations<\/strong> on a full charge \u2014 so it is not a one-shot emergency reserve, it keeps working through repeated outages. No compressed air, no spring pack, no plant-wide UPS.<\/p>\n

Four methods are used across the industry to keep a valve controllable when the power goes out. They work in different ways:<\/p>\n

Spring return needs no electricity at all but is limited by the spring. Supercapacitors hold charge only briefly. An external UPS is a plant-level investment, not a feature of the valve. A battery inside the actuator keeps the shut-off function in the actuator itself<\/em> \u2014 which is why it suits dosing lines, drain lines and skids where an uncontrolled valve position is the thing you cannot allow.<\/p>\n
