Belimo UGLK1074 Retrofit Kit

The Belimo UGLK1074 Retrofit Kit is engineered for the direct integration of Barber Colman or Siebe VB-9323 series dual valve bodies into modern building automation systems. Designed specifically for 4-inch to 6-inch globe valves, this linkage kit enables the mounting of high-torque Belimo actuators, such as the GK, AF, or GM series, without requiring system drainage or pipe disconnection. The rugged hardware ensures precise stroke synchronization and reliable close-off pressure management in high-flow hydronic applications. By utilizing this globe valve linkage, technicians can replace failing pneumatic or legacy electric actuators with electronic fail-safe technology, improving overall loop control and high-differential pressure performance. This kit is essential for contractors updating chilled water or hot water systems that utilize dual-valve configurations, providing a mechanical interface that maintains stem alignment and reduces mechanical wear over extended duty cycles.

Key Benefits:

• Compatible with Barber Colman VB-9000 series 4" through 6" dual-seat valves.
• Maintains closed-loop control accuracy by eliminating mechanical slop in the linkage.
• Supports multi-actuator mounting for increased torque requirements on large-bore globe valves.
• Heavy-duty stainless steel stem and aluminum support bracket construction for demanding mechanical rooms.
• Field-mountable design reduces labor costs and minimizes HVAC system downtime during upgrades.

Common Questions:

Can the UGLK1074 be used with non-fail-safe actuators?
Yes, this linkage is compatible with various Belimo non-spring return and fail-safe actuators, provided the torque requirements of the VB-9323 dual valve are met.

Does this kit require specialized tools for installation?
Installation is streamlined for standard technician toolsets, though precise actuator stroke calibration is necessary to ensure full seat closure.

What is the primary advantage of the dual-valve linkage over single-valve kits?
The dual-valve retrofit configuration is purpose-built to handle the unique stem travel and torque distribution required for balanced or high-capacity flow applications found in legacy Siebe installations.
