Johnson Controls VA-8050-100 Adapter

The Johnson Controls VA-8050-100 Adapter is a critical field-mounting component engineered specifically to interface VA-805x Series Electric Valve Actuators with VTM Series Terminal Unit Valves. This mounting kit provides the necessary mechanical linkage to adapt VA Series to VTM Series 1/2-inch terminal unit bodies, ensuring precise 50 lb. seating force transmission for effective flow control in HVAC installations. Designed for high-integrity floating control and incremental signaling applications, the adapter features a robust stem adapter and coupler assembly that secures the actuator yoke to the valve bonnet. This heavy-duty hardware is essential for maintaining building automation performance when retrofitting or repairing zoned heating and cooling systems. By utilizing this genuine OEM mounting kit, contractors can ensure perfect vertical alignment and full stroke travel, preventing the premature wear and calibration issues common with non-standardized field couplings in commercial HVACR environments.

• Ensures seamless actuator compatibility between the VA-8050 motor and VTM Series valve bodies.
• Delivers reliable HVAC valve linkage to maintain constant shutoff force without the need for periodic manual readjustment.
• Simplifies the valve actuator conversion process with all necessary hardware (coupler, pal nut, and stem adapter) included in one part number.
• Facilitates high-precision incremental control by eliminating mechanical play in the stem linkage.

• Is this kit required for all VA-8050 installations? Only when mounting a VA-8050, VA-8051, or VA-8052 actuator onto a VTM Series terminal unit valve body in the field.
• Does the VA-8050-100 handle steam applications? While the adapter provides the physical connection, high-temperature steam applications typically also require a separate VA-8000-101 insulator kit.
• What size valves does this adapter support? It is primarily specified for the 1/2-inch VTM series valves commonly used in VAV and fan coil unit applications.
