Pressure Independent Control Valves

OVERVIEW

Consists of two-way threaded valves ranging from ½- to 2-inches with maximum flow settings from 0.3 to 50 gpm and flanged valves with line sizes from 2½- to 6 inches with maximum flow settings from 19 to 860 gpm. The differential pressure operating range as low as 2.3 psi to as high as 90 psi. These valves control hot and chilled water with up to 50% glycol over a temperature range of 35° F to 250° F.

FEATURES

• ANSI 250 pressure class threaded valves; ANSI 125 and 250 pressure class flanged valves

• Up to 200 psi close-off with ANSI Class IV (≤0.01%) leakage

• Linear flow characteristic

• Field adjustable maximum flow presetting

• P/T ports kit (optional accessory kit for ½- to 1¼-inch valves; standard on 1½ to 6-inch valves)

• Full range of actuators available

BENEFITS

• Simplified valve sizing

• Optimized performance for greater energy savings

• Efficient installation and commissioning -- cost savings due to fewer components to install, simplified balancing and fast, trouble-free commissioning

• Greater control resolution and precision due to flow limiter being independent of the stroke of the valve

• Eliminates “hunting,” thus increasing actuator life due to fewer repositions

• System expansions do not require re-balancing of existing system

• Using P/T ports it is easy to validate that the device is operating in the design range for pressure independent functionality

APPLICATIONS

• Air handling units

• Baseboard/radiant heat

• Central plant

• Convectors

• Fan coil units

• Unit ventilators

• VAV reheat
