Johnson Controls MP823D001D Actuator

As a seasoned tech, you know that the Johnson Controls MP823D001D is a staple for reliable terminal unit control. This pneumatic valve actuator is engineered with a 25 square inch effective diaphragm area, providing the necessary force to accurately position globe valves in steam and water applications. With a 4-8 PSI spring range and a 3/4" stroke, it ensures precise linear modulation. The spring return stem up fail-safe action is critical for maintaining system safety during a loss of signal. This model features a durable 1/4" OD barbed fitting for seamless air connection and handles a 25 PSI max control pressure. The included mounting kit facilitates secure installation on compatible valve bodies, while the EPDM diaphragm and carbon steel housing resist the harsh conditions of utility rooms. Whether you are performing a piston actuator replacement or a new HVAC valve automation install, this Johnson Controls MP8000 series component delivers the mechanical consistency required for industrial-grade climate control.

• Universal Compatibility: Designed for hot water, chilled water, and steam systems using standard globe valve bodies.
• Robust Construction: Features a corrosion-resistant housing and a molded synthetic rubber diaphragm for extended field life.
• Precise Modulation: The 4-8 PSI spring range allows for fine-tuned sequencing in complex pneumatic logic circuits.
• Field Reliability: The spring-return mechanism ensures the valve stem returns to the up position immediately upon pressure loss.

What is the maximum air pressure for the MP823D001D?
The unit is rated for a 25 PSI maximum control pressure. Exceeding this can damage the EPDM diaphragm.

Is the mounting kit included with this specific model number?
Yes, the MP823D001D comes factory-packed with the necessary mounting hardware for standard installation.

Can this actuator be used for steam applications?
Absolutely. It is designed to position valves for steam, hot water, and chilled water accurately.
