Pressure Independent Control Valves

VRN Pressure Independent Control Valves And Actuators

The VRN2 two-way dynamic pressure-regulating control valves maintain constant flow of hot or chilled water in HVAC systems.

Overview

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 & Benefits:
  • Sizes from 1/2 to 3 in. with internal (female) NPT connections.
  • Regulated flow rates available from 1 to 95 gpm with multiple maximum flow rates available per valve size.
  • 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.
  • Patented ball seals for low operating torque.
  • Nickel-chrome plated brass or stainless steel trim.
  • Choice of factory-installed actuation: floating, modulating (2-10 V), spring return or non-spring return 2-Position, Spring Return Modulating/Floating, Spring Return Sylk-enabled.
  • 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.
