Belimo ZG-GV05 Rebuild Kit

For veteran contractors servicing high-capacity hydronic systems, the Belimo ZG-GV05 Rebuild Kit is the industry-standard solution for refurbishing 2.5-inch Belimo globe valves. Specifically engineered for the G665 and G665-250 series, this comprehensive valve repair kit allows technicians to restore original seat integrity and flow control precision without the labor-intensive process of replacing the entire valve body. Whether you are addressing HVAC valve maintenance in chilled water or hot water applications, this kit provides the necessary OEM replacement parts to eliminate bypass leakage and ensure accurate linear or equal-percentage flow characteristics. By installing the Belimo globe valve rebuild components, you maintain the tight shut-off required for modern building automation systems, reducing actuator strain and extending the operational life of the assembly. This 2.5" valve service kit is essential for maintaining peak system efficiency and reliable pressure independent control performance in demanding commercial environments.

Key Benefits

• Precision Compatibility: Designed specifically for 2.5-inch G665 series globe valves, ensuring a perfect fit and reliable seal.
• Enhanced Flow Control: Restores the valve’s internal geometry, maintaining critical HVAC flow regulation and thermal comfort levels.
• OEM Durability: Includes high-grade Belimo genuine parts that withstand the thermal cycling common in hydronic heating and cooling.
• Operational Efficiency: Eliminates internal leakage and "hunting" actuator symptoms, optimizing the performance of chilled water systems.

Common Questions

Which valve models is this kit compatible with?
The ZG-GV05 is designed for 2.5" Belimo G665 and the high-pressure G665-250 models. For "S" (Stainless Steel) trim versions, verify if the ZG-GV29 is required instead.

What are the signs that a 2.5" globe valve needs a rebuild?
Technicians should look for valve bypass leakage when the actuator is fully closed, visible stem packing leaks, or hunting behavior where the actuator cannot maintain a steady setpoint due to internal wear.

Does this kit include the stem packing?
Rebuild kits typically focus on internal trim components including the plug and seat. For simplified stem-only repairs, a separate repacking kit like the ZG-GV15 may be more appropriate depending on the specific failure point.
