Belimo G220S-J Valve

The Belimo G220S-J is a high-performance 3/4 inch 2-way globe valve engineered specifically for modulating control in demanding HVAC applications. Constructed with a rugged bronze body and stainless steel trim, this valve is designed to handle chilled or hot water and steam applications with a maximum pressure rating of 250 psi (ANSI Class 250). The 5.5 Cv rating, combined with a modified equal percentage flow characteristic, ensures precise linear control of flow rates, preventing hunting in automated systems. This stem-up-to-open model features an NPT threaded connection, making it compatible with a wide range of standard piping configurations. Utilizing a stainless steel valve stem and seat provides superior resistance against erhrosive flow and scaling, maintaining long-term tight shut-off and reliable performance in high-cycle hydronic loops.

Key Benefits

• Superior Durability: The stainless steel trim and bronze construction resist corrosion and wear in high-temperature steam systems.
• Precise Modulation: Features a modified equal percentage flow curve for stable temperature control and optimized energy efficiency.
• High Close-Off Pressure: Engineered to provide reliable shut-off even in high-differential pressure environments typical of industrial HVAC.
• Standardized Compatibility: The 3/4" NPT ports allow for seamless integration with Belimo globe valve actuators.

Common Questions

What is the maximum steam pressure for the G220S-J?
The G220S-J globe valve is rated for up to 35 psi of saturated steam, making it suitable for low-pressure terminal equipment and heat exchangers.

Which actuators are compatible with this 3/4 inch globe valve?
This valve is designed to interface with Belimo LV and SV series actuators, providing versatile control options for various building automation protocols.

How does the stem-up-to-open configuration affect system design?
In a stem-up-to-open configuration, the valve remains closed when the stem is down, which is a critical specification for identifying the correct fail-safe position in your control valve assembly.
