The Honeywell VRN2G2PXB102 is a two-way pressure independent control valve and actuator assembly. It ensures a steady flow of hot or chilled water, even with up to 50% glycol solutions, in closed-loop HVAC systems. This valve is designed for consistent performance despite variations in pressure. The assembly features a built-in pressure control cartridge that assists with flow balancing, making it ideal for various HVAC applications. The valve is compatible with Honeywell direct coupled actuators and has a durable forged brass body with female NPT connections.
Maintains constant flow regardless of pressure fluctuations.
Features an integrated pressure control cartridge.
Suitable for hot or chilled water with up to 50% glycol solutions.
Product Highlights
This valve and actuator assembly is essential for HVAC systems requiring stable flow control and compatibility with different heating and cooling mediums.
