Johnson Controls MP822D001A Actuator

The Johnson Controls MP822D001A is a 25-square-inch pneumatic valve actuator designed for precise proportional control in HVAC systems. Engineered for high-temperature and high-pressure steam or water applications, this spring return stem up actuator features a 4-8 PSI spring range and a 1/2-inch stroke length. The heavy-duty diaphragm actuator construction ensures consistent performance under a 25 PSI maximum control pressure. Equipped with a 1/4" OD barbed fitting air connection, the MP822D001A facilitates straightforward integration into existing pneumatic lines. The included mounting kit streamlines the installation process, allowing for direct attachment to compatible Johnson Controls globe valves. This actuator is a reliable solution for contractors managing terminal unit or air handling systems where fail-safe positioning is required during loss of signal or power. Its rugged design minimizes maintenance requirements while maintaining accurate valve positioning across the specified pneumatic control signals.

Technical Key Benefits
