Product Description The Honeywell VRN2ADSX4002 is a pressure independent control valve assembly designed for hydronic systems. This valve autonomously manages flow to uphold consistent temperatures despite changes in piping pressures. It boasts an integrated pressure control cartridge facilitating flow balancing and ensuring proper control.
Comes with a stainless steel trim for durability.
Floating on/off actuator ensures reliable operation.
Requires a 24 VAC supply voltage for functionality.
Product Highlights Ideal for applications needing precise temperature control and flow management in hydronic systems.
