Honeywell VRN2HUSXA102 Pressure Independent Control Valve & Actuator Assembly 3" 45GPM 2-Position Spring Return Normally Open 24V with Auxiliary Switch

The VRN2 two-way pressure independent control valves maintain constant flow of hot or chilled water with glycol solutions up to 50% in closed-loop heating, ventilating, and air conditioning (HVAC Division 23) systems regardless of head pressure fluctuations above the minimum specified pressure drop. These valve assemblies can be used with Honeywell non-spring return or spring return direct coupled actuators (DCA).

The built-in differential pressure regulator makes fluid flow through the valve independent of changes in supply pressure, eliminating “hunting” by the control system, even at low coil flow. The pressure regulator virtually eliminates cavitation in the valve, and decouples the control valve from the effects of piping components such as reducers and elbows.

Pressure independent control valves are sized to match design coil flow regardless of coil size. VRN2 valves eliminate the need to balance the system for proper flow, and allow chillers to be operated at design temperature differential for maximum efficiency at every load condition. When used in a system with variable speed pump drives, 3-way valves and coil bypass lines are not required. In new construction, VRN2 valves perform better than reverse return piping designs without the extra materials these systems need.

Pressure-independent control requires less flow, enabling use of smaller piping, pumps, and chillers.
