Johnson Controls MP845E001F Valve Actuator

The Johnson Controls MP845E001F is a robust pneumatic valve actuator specifically engineered to deliver precise modulation for chilled water, hot water, and steam control valves. Built for high-demand commercial HVACR environments, this 50 square inch actuator provides a reliable 1 1/8" stroke, ensuring accurate valve positioning in response to a pneumatic signal. The unit features a 9-13 PSI spring range and support for a 25 PSI max control pressure, allowing for versatile integration into varied control loops.

Designed with a spring return stem up configuration, the MP845E001F utilizes a durable, molded synthetic rubber diaphragm and a corrosion-resistant housing to withstand harsh mechanical room conditions. The 1/4" OD barbed fitting air connection facilitates a secure, leak-free pneumatic link. This model includes a comprehensive mounting kit, streamlining the installation process for technicians. Whether you are managing steam heat or complex chilled water systems, the MP845E001F provides the mechanical force and linearity required for optimized building automation performance.

• Universal Application: Compatible with steam, hot water, and chilled water valve assemblies.
• Precise Control: 9-13 PSI spring range ensures accurate modulation and stable valve seating.
• Field Reliability: Durable carbon steel housing and EPDM diaphragm resist environmental wear and tear.
• Ease of Install: Includes specialized mounting hardware and a 1/4" barbed fitting for rapid pneumatic connection.
• Visual Feedback: Integrated position indicator allows for quick manual verification of the valve stem status.

What is the maximum pressure this actuator can handle?
The MP845E001F is rated for a 25 PSI max control pressure. Exceeding this limit may compromise the synthetic rubber diaphragm.

Is the action reversible in the field?
Yes, the MP8000 series design allows for field-reversible action, permitting technicians to switch between spring-return-up and spring-return-down configurations as needed for N.O. (Normally Open) valves.

Does this unit come with the necessary mounting hardware?
Yes, this model is supplied as a complete assembly with the required mounting kit for standard valve integration.
