The Honeywell VRN2DPPX9202 is a pressure independent control valve and actuator assembly designed for HVAC systems. This two-way valve ensures a constant flow of hot or chilled water, mixed with up to fifty percent glycol, in closed-loop systems. It features an integrated pressure control cartridge which allows for precise flow balancing and effective temperature control. The assembly includes a differential pressure regulator, making fluid movement unaffected by changes in supply pressure. It is compatible with Honeywell's direct coupled actuators.
Maintains constant flow regardless of pressure fluctuations.
Features a differential pressure regulator.
Suitable for hot or chilled water with up to 50% glycol solutions.
Product Highlights
This control valve is suitable for diverse HVAC applications, enhancing energy efficiency and system performance.
