M9000-520 Ball Valve Linkage Kit Product Bulletin资料下载
The M9000-520 Ball Valve Linkage Kit is designed specifically for field mounting Johnson Controls® M9106 and M9109 Series Non-Spring Return, and M9206 Series Spring Return Electric Actuators to Johnson Controls VG1241, VG1245, VG1841, and VG1845 Series Ball Valves. The use of
glass-reinforced thermoplastic resin provides superior thermal isolation between the valve and actuator, minimizing heat transfer in higher fluid temperature applications and preventing condensation in chilled water applications.
Linkage Kit Selection
Use the M9000-520 Valve Linkage Kit to field mount Johnson Controls M9106 or M9109 Series Non-Spring Return, and M9206 Series Spring Return Electric Actuators to Johnson Controls VG1241, VG1245, VG1841, and VG1845 Series Ball Valves. The use of glass-reinforced thermoplastic resin and the height of the linkage kit allow for the use of pipe insulation that minimizes heat transfer to the actuator. In chilled water applications, the use of thermoplastic resin also prevents condensation. Use the manual handle supplied with the linkage kit to manually position the non-spring return electric actuators when power is off and the actuator gears are disengaged.
To minimize heat transfer in steam applications, wrap the valve and piping with insulation. Allow sufficient clearance for actuator removal (as illustrated in
Figure 2 and Figure 3).
Before installing the electric actuator, use an adjustable wrench to manually rotate the valve stem several times. Rotating the valve stem breaks the torque that may have built up during long-term storage.
Wire all electrically actuated VG1000 Series Ball Valves in accordance with applicable electrical code requirements. Wire the input lines to the electric actuator correctly so that the valve moves in the proper direction.
On reduced port models, the flow-characterizing disk is located in Port A. Port A must be the inlet.
Contact the local Johnson Controls representative for compatibility concerns before using VG1000 Series Ball Valves to control the flow of fluids other than those outlined in the Technical Specifications table at the end of this document.
