Belimo G665C Valve

The Belimo G665C is a professional-grade 2.5-inch 2-way globe valve designed for precise flow control in demanding hydronic systems. Engineered as the direct replacement for the legacy G665 model, this flanged assembly features a CV 65 rating and a pressure-compensated design to maintain stable performance across varying differential pressures. The bronze trim and cast iron body construction ensure long-term durability in closed-loop chilled or hot water applications. This valve is built for ANSI Class 125 flanged connections, facilitating seamless integration into heavy-duty mechanical piping. It provides an equal percentage flow characteristic for superior modulating control, making it a reliable choice for air handling units and heat exchangers. Proper actuator scaling and linkage alignment are critical for maintaining the tight shut-off required in high-performance HVACR environments. This unit is optimized for HVAC water-side control where high flow capacity and robust construction are non-negotiable.

Key Benefits for Technician Installation

• Direct Retrofit Compatibility: Specifically engineered as the updated version for the G665, ensuring easier field replacements with existing piping layouts.
• High Flow Efficiency: A 65 CV rating allows for significant volume throughput with minimal pressure drop across the valve body.
• Superior Material Integrity: Features bronze trim and a stainless steel stem to resist corrosion and prevent scaling in commercial water systems.
• Linear Motion Accuracy: The globe valve architecture provides precise throttling capabilities compared to standard ball valves.
• Standardized Flange Mounting: Designed for ANSI 125 pipe flanging, reducing labor time during heavy-duty mechanical installations.

Common Questions Regarding the G665C

What is the primary difference between the G665 and G665C?
The G665C is the current production standard, replacing the older G665 model with improved internal sealing and pressure compensation features while maintaining the same face-to-face dimensions.

Can this valve be field-paired with different actuators?
Yes, the G665C is compatible with various Belimo globe valve actuators (such as the EV, AVK, or RV series), depending on the torque and fail-safe requirements of your specific sequence of operations.

Is the G665C suitable for steam applications?
This specific configuration with bronze trim is primarily designed for water-based applications. For high-pressure steam, verify that the temperature ratings and trim materials meet your project's specific PSI requirements.
