O.D. plastic tubing Diameter 2-1/4 in. Height 3-3/16 in. maximum Construction Durable Honeywell design Weight 3 lbs   Information About MP958A1009 The MP958A1009 is part of Honeywell’s pneumatic actuator series, specifically engineered for valve and damper control in HVAC applications. It features a compact body measuring 2-1/4 inches in diameter and 3-3/16 inches in height, allowing installation in space-restricted areas. With a direct-acting mechanism, it responds proportionally to increasing air pressure, and its 2–5 PSI spring range ensures precise modulation in low-pressure control loops. The actuator includes a spring return fail-safe mode for automatic repositioning in the event of air supply loss, and it connects via a barbed fitting for 1/4-inch O.D. plastic tubing to simplify pneumatic integration. Designed for durability, it supports up to 30 PSI maximum safe operating pressure without compromising performance. Key Features: Low-force pneumatic control: Specifically engineered for applications where minimal actuator force is required, ensuring smooth operation in sensitive valve or damper mechanisms without overloading the system. Direct-acting operation: Responds proportionally to increases in control air pressure, moving the actuator stem in a consistent and predictable manner to deliver precise valve positioning. 2–5 PSI calibrated spring range: Provides accurate modulation in low-pressure pneumatic systems, allowing fine adjustments for optimal air balancing and HVAC performance. Spring return fail-safe mode: Uses a built-in spring mechanism to automatically return the actuator to a predetermined safe position when the air supply is lost, protecting the system during power or control failures. Compact form factor for tight spaces: With a diameter of just 2-1/4 inches and height of 3-3/16 inches, it can be installed in confined mechanical spaces without the need for extensive mounting modifications. High-pressure durability: Built to safely withstand up to 30 PSI without damage, offering a substantial safety margin for demanding pneumatic environments. The MP958A1009 delivers the reliability and precision required for accurate pneumatic valve and damper control in HVAC systems.
