VRN Pressure Independent Control

Valves and Actuators

APPLICATION

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.

FEATURES

• Sizes from 1/2 to 3 in. with internal (female) NPT

connections.

• Controls hot or chilled water with up to 50% glycol.

• Regulated flow rates available from 1 to 95 gpm.

• Differential pressure regulator for constant pressure

drop across valve seat.

• Positive pressure, rolling diaphragm regulator design

for flow control accuracy of ±5%.

• Equal percentage flow characteristic using patented

flow control ball insert.

• Multiple maximum flow rates available per valve size.

• Patented ball seals for low operating torque.

• Nickel-chrome plated brass or stainless steel trim.

• Choice of factory-installed actuation using

Honeywell MVN or MN/MS series direct coupled

actuators: Floating, Modulating (2-10 V), Non-Spring

Return and Spring Return.

• Spring return actuators field-configurable for

normally open or normally closed fail-safe position.

• Removable, manual operating handle to control

valve during installation or in an event of power

failure.

• Upstream Test Port for venting or pressure gauge

attachment.

• Three actuator orientations on the valve for cramped

spaces.

• Integral snubber eliminates effect of system

pressure fluctuations and entrapped air while

improving flow performance.
