Pressure Independent Flow Control Valves include the VRN threaded and VRW flanged valve families. These valves maintain flow under varying differential pressures and increase coil differential temperature which improves HVAC system efficiency. An integrated pressure control cartridge combines circuit balancing and control functions in one package, resulting in consistent temperature and comfort. Valves have field serviceable stem and pressure regulating cartridge allow for easy service.
The VRN2 two-way dynamic pressure independent control ball valves maintain constant flow of hot/chilled water in closed loop heating, ventilating, and air conditioning (HVAC) systems regardless of head pressure fluctuation above minimum pressure drop.
The VRN2 two-way dynamic 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
VRW2 two-way dynamic pressure independent control valves maintain constant flow of hot or chilled water in closed-loop heating, ventilating, and air conditioning (HVAC) systems regardless of head pressure fluctuations above minimum pressure drop.
