- Even if there is a pressure fluctuation on the inlet side, stable decompression operation can be obtained with almost no effect on the set pressure.
- Since the outlet side pressure directly operates the valve body, hunting hardly occurs, the internal structure is simple, and there are Applications almost no troubles.

OPTIMA Compact DN10-DN50
Read moreDesigned to combine automatic balancing and full modulating control regardless of the preset flow.
The innovative design of OPTIMA Compact introduces an intelligent control valve that adjusts automatically to the preset flow in order to provide full modulating control. When the installer presets the valve according to the maximum designed flow, the stroke of the control valve remains the same thus providing 100% modulating control.
In practical terms, OPTIMA Compact ensures that there is no overflow and that below the design flow the actuator has absolute authority. Furthermore, OPTIMA Compact combines all those features that are necessary to ease the work of designers and installers:
- The wide (up to 800kPa) differential pressure range meets the requirements of most applications
- The compact design and the user-friendly presetting unit guarantee easy installation and commissioning.

OPTIMA Compact DN50-DN300
Read moreWith OPTIMA Compact you get a dynamic flow and temperature control valve for heating and cooling systems
OPTIMA Compact combines the functions of an externally adjustable dynamic balancing valve, a differential pressure control valve and a full authority modulating control valve in one single, compact valve housing.
The OPTIMA Compact provides modulating control with full authority regardless of variations in the differential pressure of the system making it possible to achieve 100% control of the water flow in the building.
In addition, the correct application of the OPTIMA Compact can significantly reduce pump energy consumption and improve the efficiency of other hydronic system components. It also provides optimal comfort for end users due to high precision temperature control.
The valve operates by adjusting automatically to the pre-set flow under fluctuating pressure conditions whilst also providing full modulating control. To achieve the design flow rate, the simple pre-setting scale on top of the valve is rotated to the required set point, which can be determined by using the Frese flow tables or the Frese Valves app.

OPTIMA Compact Veriflow-series DN10-DN50
Read moreOPTIMA Compact Veriflow 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.
The unique P/T plug design allows for both flow verification and verification of minimum differential pressure across the whole valve for optimal pump energy saving.
OPTIMA Compact Veriflow provides modulating control with full authority regardless of any fluctuations in the differential pressure of the system.
OPTIMA Compact Veriflow combines an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve.
OPTIMA Compact Veriflow makes it simple to achieve 100% control of the water flow in the building, while creating high comfort and energy savings at the same time.
An additional benefit is that no balancing is required if further stages are added to the system, or if the dimensioned capacity is changed.
Energy saving due to optimal control, lower flow and pump pressure. Maximized ∆T due to faster response and increased system stability.

Frese STBV FODRV
Read moreFODRV – DN15-DN300
The Frese FODRV is a Fixed Orifice Double Regulating Valve for flow balancing and verification.
The Frese FODRV is ideally suited for use in heating and cooling applications for the balancing and accurate verification of flow in various sections of the system. The Frese FODRV balancing valve ensures simple and reliable verification of the system and can be installed in both variable flow systems and constant flow systems.
The double regulating valve feature allows the valve to be set to the required position and locked thus limiting the opening of the valve. If required, the valve can then be isolated by turning the hand wheel to set point 0.0 and reopened to the previous set point.
The integral fixed orifice, which has a fixed dimension and geometry, induces a difference in pressure for flow measurement.
