The Honeywell MP953C1471 is engineered as a pneumatic globe valve actuator, specifically categorized as direct acting. Its physical dimensions include a 13-inch actuator diameter and a total weight of 22.64 lbs, supporting its solid construction suitable for various applications. The actuator is designed to function effectively in fail-safe mode via a spring return mechanism, ensuring reliability in the event of a control system failure.
The actuator operates within a spring range of 2 to 7 psi (14 to 48 kPa), with a maximum safe operating pressure rating of 25 psi (172 kPa or 173 kPa). It is capable of performing in ambient temperature conditions ranging from -18°C to 60°C, alongside humidity levels spanning from 5% to 95% RH while remaining non-condensing. The versatility of this actuator extends to its fluid temperature management, as it can handle fluid temperatures up to 338°F (170°C), making it suitable for both water and steam applications.
Furthermore, the actuator utilizes a rolling diaphragm mechanism, contributing to reduced hysteresis and promoting an extended operational life. It is essential to note that this model does not come equipped with a positioner. The combination of these specifications makes the Honeywell MP953C1471 an effective choice for precise and reliable valve control in diverse industrial environments.
