Frese Optima Compact Pressure Independent Balancing & Control Valve 53-1338 3/4Inch, Dn20/Pn25 M/M High 5 P/T, Ac Chiller Water Actuator Valve, Made In Denmark

The presetting function has no impact on the stroke; Full stroke modulation at all times, regardless the preset flow. The constant differential pressure across the modulating control component guarantees 100% authority.
Automatic balancing eliminates overflows, regardless of fluctuating pressure conditions in the system. Compatible for almost actuators Thermic actuator On/Off or 0-10V, normally closed, Motoric actuator 0-10V, (Linear or Logarithmic) or 3 point control.
Differential pressure operating range up to 800 kPa High flows with minimal required differential pressure due to advanced design of the valve Small dimensions due to compact housing,
High comfort for the end-users due to high precision temperature control Longer life due to less movements of the actuator
Frese OPTIMA Compact pressure independent balancing & control valve (PIBCV) is used in heating and cooling systems in applications with Fan Coil Units, Chilled Beams or other terminal unit applications.
