Description
The Honeywell MP953E1301 is a direct-acting pneumatic coil valve actuator engineered for precise proportional control of steam, hot water, and cold liquid systems in commercial and industrial HVAC applications. With a factory-calibrated 4–11 PSI spring range and a 3/4″ stroke, this spring-return actuator delivers reliable, repeatable valve positioning in response to pneumatic control signals — making it a proven choice for air-handling units, fan coil systems, and hydronic distribution networks.
The MP953E1301 features a dual barbed fitting that accommodates both 5/32″ and 1/4″ OD plastic tubing, simplifying field installation and reducing the need for additional adapters. Its spring-return design ensures the valve returns to a fail-safe position upon loss of air pressure, providing an added layer of system protection.
