It delivers a 4-inch stroke and a 4–8 psig (28–55 kPa) spring range, with a 1\/4 in. O.D. barbed air connection and a clevis-and-pin linkage for attaching to the damper arm. Designed for either proportional or two-position control, it operates on clean, dry, oil-free air supplied at nominal 20 psig with a maximum of 30 psig, making it suitable for HVAC dampers in equipment like air-handling units and zone dampers. The M574-8520’s post-mount configuration, pre-installed clevis\/pin, and compatibility with standard damper assemblies help ensure reliable, repeatable positioning across a range of dampers and control schemes.\u003c\/p\u003e\u003c\/div\u003e","brand":"Schneider","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46283974607082,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-021.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-m574-8520-pneumatic-damper-actuator","provider":"GTG Hardware","version":"1.0","type":"link"}
