It delivers 360 in-lb (40 Nm) of torque to reliably position damper blades in ventilation systems and is a modulating actuator that accepts a 2–10 V DC control signal for proportional airflow control. Powered from 24 VAC (AC\/DC 24 V), the unit includes an electronic fail-safe mechanism that drives the damper to a predefined fail position when power is removed, supporting safety and smoke-control requirements. Designed for commercial HVAC use, this model is well suited for dampers in air-handling units, mixing boxes, and economizers where precise, dependable fail-safe operation is essential. As part of Belimo’s fail-safe family, the GKB24-SR blends robust torque with modulating control and a spring-return action to deliver reliable performance in challenging environments. \u003c\/p\u003e\u003c\/div\u003e","brand":"BELIMO","offers":[{"title":"New","offer_id":51676863463726,"sku":null,"price":526.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_53dbab6a-a5d0-49c5-8c7d-1166a635324b.jpg?v=1769554481","url":"https:\/\/plgautomation.com\/products\/belimo-gkb24-sr-damper-actuator-24-vac-spring-return","provider":"PLG Automation ","version":"1.0","type":"link"}
