MP822E001 Johnson Controls Actuator

Part number MP822E001 from Johnson Controls, listed in Valves & Process Control. KKM Solutions quotes this part with pricing and availability confirmed per order.

Overview The Johnson Controls MP822E001 is an MP8000 Series pneumatic valve actuator designed to accurately position hot water, chilled water, and steam control valves in commercial and industrial HVAC systems. It features a molded synthetic rubber diaphragm contained within a sturdy, corrosion-resistant housing that protects against dirt and damage while ensuring a constant effective area throughout the actuator stroke. This model operates with a fail-safe spring return stem-up action, returning the valve to a defined safe position upon loss of supply air pressure. Features Field-reversible action allows for flexible on-site adjustments Sturdy, corrosion-resistant steel housing and yoke ensure long service life Molded synthetic rubber diaphragm provides a constant effective area throughout the stroke Position indicator included with every actuator for clear visual confirmation of valve stem position Universal-application design suitable for hot water, chilled water, and steam environments Accommodates optional auxiliary switches, feedback potentiometers, or positioners for enhanced control Specifications Model: MP822E001 Actuator Type: Pneumatic Valve Actuator Diaphragm Area: 25 square inches Spring Range: 9 to 13 PSI (60 to 90 kPa) Stroke Length: 1/2 inch (13 mm) Maximum Control Air Pressure: 25 PSI (172 kPa) Fail-Safe Mode: Spring Return (Stem Up) Air Connection: Barbed fitting for 1/4 inch O.D. polytubing Compatible Valve Sizes: Typically engineered for 1 inch to 2 inch globe valves (and select applications up to 3 inches) Operating Temperature Range: -20 to 150 degrees Fahrenheit (-29 to 66 degrees Celsius) Applications The MP822E001 is ideal for integration into commercial building automation systems, air handling units, and hydronic heating or cooling systems where precise control of fluid flow is essential. Because it provides a reliable fail-safe position on air failure, it is frequently utilized in critical HVAC control loops where system safety and automated shutoff protocols require the valve to return to a defined position.
