Honeywell VRN2, VRN User Manual

VRN Pressure Independent Control

Valves and Actuators

PRODUCT DATA

APPLICATION

The VRN2 two-way dynamic pressure-regulating control valves maintain constant flow of hot or chilled water with glycol solutions up to 50% in closed-loop heating, ventilating, and air conditioning systems, within the specified pressure drop ranges of each model number. These valve assemblies can be ordered with or without factory-mounted actuators.

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.
