The Honeywell VRN2H2PX4000 is a pressure independent control valve and actuator assembly designed for hydronic systems. This valve combines flow and temperature control, allowing consistent hot or chilled water flow with up to fifty percent glycol. It is engineered to handle pressure fluctuations effectively and includes a pressure control cartridge for accurate flow balancing. This assembly works seamlessly with Honeywell direct-coupled actuators and is ideal for closed-loop HVAC systems.
Supports sizes from half an inch to three inches with female NPT connections.
Designed for water or glycol solutions up to fifty percent.
Incorporates a differential pressure regulator for maintaining constant pressure.
Product Highlights
This valve and actuator assembly is engineered for use in heating, ventilating, and air conditioning systems, providing reliable temperature and flow regulation.
