Frese provides perfect control
Published: July 2009
Designed to provide perfect indoor climate control, the Frese Optima pressure-independent control valve (PICV) combines three functions in a single valve housing. The Optima PICV limits flow from 0.021 to 0.83 l/s, regulates differential pressure from 16 to 400 kPa and offers full 5.5 mm stroke modulation to ensure design flow is achieved even under fluctuating system pressures. Using the Optima PICV with variable-speed pumps also offers significant energy savings on CHW and LTHW systems. The Optima PICV can be assembled in a modular arrangement that is pre-fabricated and tested off-site for use with fan-coil units and active chilled beams.
