Johnson Controls M9000-561 Thermal Barrier Kit for Ball Valve Linkages

The Johnson Controls M9000-561 is a thermal barrier kit designed to protect electric spring-return actuators in high-temperature and steam applications. This kit extends the application of M(VA)9104, M(VA)9203, and M(VA)9208 series electric spring-return actuators to include low-pressure steam systems. The thermal barrier is specifically designed for use with M9000-560 ball valve linkages.

Key Features:

• Thermal insulator protects ball valve actuators in high temperature and steam applications
• Maximum fluid temperature of 284°F and maximum steam pressure of 15 PSI
• Kit includes barrier, drive shaft, flange nuts, and machine screws
• Constructed from thermoplastic resin material
• Permits use of M(VA) 9xxx actuators on VG1000 valves with low pressure steam
• Made in United States

The barrier helps maintain valve integrity by reducing heat transfer and fits between the actuator and valve to ensure proper operation in demanding steam environments. This thermal barrier enhances safety by protecting both personnel and equipment from high temperatures in steam system installations.
