Pressure Independent Control & Balancing Valves

Frese OPTIMA Compact

Pressure independent control valve

Design

  • Less time to define the necessary equipment for a hydraulic balanced system (only flow data are required)
  • No need to calculate valve authority
  • Flexibility if the system is modified after the initial installation

Installation

  • No further regulating valves required in the distribution pipework when Frese OPTIMA is installed at terminals.
  • Total number of valves minimized due to the 3-in-1 design
  • Minimized commissioning time due to automatic balancing of the system
  • No minimum straight pipe lengths required before or after the valve.

Operation

  • High comfort for the end-users due to high precision temperature control
  • Longer life due to less movements of the actuator

Features

  • The presetting function has no impact on the stroke; Fullstroke 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.
  • Flushing through the valve is possible due to the removable cartridge feature
  • Electrical actuator 0-10 V and 3 point control, normally closed
  • Differential pressure operating range up to 400 kPa
  • High flows with minimal required differential pressure due to advanced design of the valve
  • More accurate control due to long 5.5 mm stroke
  • Higher presetting precision due to stepless analogue scale

Frese OPTIMA Compact

Pressure independent balancing & control valve

Frese OPTIMA Compact combines an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve. Used in heating and cooling systems Frese OPTIMA Compact (PIBCV) fits applications with air handling units, heat exhangers or mixing circuits.
