Johnson Controls M9000-532 Linkage

The Johnson Controls M9000-532 is a heavy-duty linkage kit engineered for mounting tandem electric actuators onto flanged iron globe valves. Designed for high-torque applications, this linkage facilitates the installation of M9116, M9124, and M9220 non-spring return actuators or M9220 spring-return models. Specifically, it supports 3-inch valves when utilizing tandem M9116, M9124, or M9220 units, and 4-inch valves with tandem M9124 or M9220 configurations. This HVAC valve linkage ensures precise linear motion transfer from the dual-drive actuators to the valve stem, maintaining reliable flow control in large-scale hydronic systems. The robust construction minimizes hysteresis and mechanical play, essential for maintaining tight building automation system tolerances. By doubling the available torque via a tandem arrangement, the M9000-532 provides the necessary force to overcome high close-off pressures in chilled or hot water applications without stalling the motors.

Key Benefits

• High-Torque Capacity: Specifically designed to handle the combined output of tandem-mounted actuators for large-diameter valve stems.
• Broad Compatibility: Supports a wide range of JCI M9000 series actuators including M9116, M9124, and M9220 families.
• Durable Construction: Built with industrial-grade materials to withstand the mechanical stress of high-force spring-return operations.
• Field-Serviceable Design: Simplifies the integration of actuators to VG7000 series flanged valves, reducing labor time during retrofits.
• Precision Control: Ensures consistent valve stroke and seating force to prevent leakage and improve energy efficiency.

Common Questions

What valves are compatible with the M9000-532?
This linkage is purpose-built for 3-inch and 4-inch Johnson Controls flanged iron globe valves, specifically those requiring the higher torque provided by dual actuators.

Can I use this for both spring-return and non-spring return actuators?
Yes, it is compatible with tandem M9116, M9124, and M9220 non-spring return actuators, as well as the M9220 spring-return series.

Why is a tandem mounting necessary for 4-inch valves?
Larger globe valves often encounter high differential pressures that exceed the torque rating of a single actuator; the tandem configuration ensures a reliable seal and movement under load.
