When 230V power is applied, the PTC heating element expands the paraffin propulsion element, pushing the valve stem to close the valve. This is ideal for fail-safe heating applications where flow should continue if power is lost.\u003c\/p\u003e\n\u003ch4\u003eQ: Which valve bodies is this actuator compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: The N58A actuator uses a standard M30×1.5 nut thread connection, which fits the vast majority of manifold branch valves, small zone valves, and dynamic balancing valves used in underfloor heating systems. Always verify your valve body thread size before purchasing.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this actuator suitable for 120V systems?\u003c\/h4\u003e\n\u003cp\u003eA: No. This model is rated for 230VAC (50\/60Hz) only. It is not compatible with 120V North American systems. Please ensure your heating control system and thermostat output match the 230V requirement before installation.\u003c\/p\u003e\n\u003ch4\u003eQ: How long does it take to fully open or close?\u003c\/h4\u003e\n\u003cp\u003eA: The full travel time (open to close or close to open) is between 180 seconds and 300 seconds (3 to 5 minutes), which is typical for thermal actuators and helps prevent water hammer in hydronic heating systems.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does \\\"normally open\\\" (NO) mean for this thermal actuator?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A normally open actuator means the valve is in the open (flow-passing) position when no power is supplied.
