OPTIMA P Compact

Pressure Independent Control Valve with differential pressure control

Frese OPTIMA P Compact pressure independent balancing & control valve with external differential pressure control is used in heating systems in applications with Radiators.

Frese OPTIMA P Compact provides modulating control and ensures differential pressure control over the radiator system, to avoid noise and a provide a better control for the radiator valves.

Benefits

Design

• Easy to install and adjust according to pre-defined flow.
• The valves automatically find the hydraulic balance regardless of pressure fluctuations in the system.
• No main circuit or branch balancing valves needed in the system.
• Systems with automatic balancing are flexible, as they do not require readjustment of the ”original” circuit in case the system is extended after installation.
• Less time to define the necessary equipment for a hydraulic balanced system.

Installation

• Total number of valves minimized due to the multi functional 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; Full stroke modulation at all times, regardless the preset flow.

• The limitation of the differential pressure across radiator system eliminates nose.

• Automatic balancing eliminates overflows, regardless of fluctuating pressure conditions in the system.

• Thermal actuator On/Off or 0-10V, normally closed.

• Differential pressure operating range up to 800 kPa.

• Leakage rate according to EN1349 Class IV (0,01%).

• Isolation up to 10 Bar when fitted with isolation cap.

• Small dimensions due to compact housing.

• Higher presetting precision due to stepless analogue scale.
