Optima Model Full Stroke Modulation&Automatic Balancing Valves  >>  FRESE OPTIMA Low Flow

FRESE Optima Compact

The new Frese Optima combination valve is designed to combine automatic balancing and full modulating control regardless of the preset flow. The innovative design of Frese Optima introduces an intelligent control valve that adjusts itself automatically to the preset flow in order to provide full stroke modulating control. When the installer presets the valve according to the maximum design flow, the stroke of the control valve remains the same thus providing 100% modulating control. In practical terms, Optima ensures there are no overflows and that below the design flow, the actuator has total authority.

The actuated valve shall operate by means of an automatic balancing cartridge that can be removed without dismantling the valve. The presetting of the valve shall not influence the length of the stroke. The pressure class shall be PN25. The differential pressure operating range shall be up to 400kPa. The valve shall operate by means of an electrical modulating actuator
