Frese cross-reference FAQ

How do I cross-reference a Frese valve?

Start with the source model, open its dedicated equivalent page, then verify connection, pressure, material, and actuation before sourcing a replacement.

Are Frese valve equivalents dimensionally identical?

Not always. ValveXRef surfaces likely alternatives, but fit, pressure class, and control method still need to be confirmed on the specification page.

When should I use the brand page instead of a model page?

Use the brand page when you only know the manufacturer or family. Use the model-level cross-reference page when you already have a specific part number.

Frese By design, the valve has a high Kv value which means it achieves the lowest pressure loss of any comparable differential pressure control valve on the market. Due to fluctuating differential pressures, heating and cooling systems often create noise because the thermostatic control valves are unable to close completely. Despite the more regular use of variable speed pumps, in larger systems the differential pressure will increase when the system is in a partial load condition. This causes an increase in system noise and the control valves to regulate inefficiently. The PV Compact Valve ensures a constant differential pressure across the load or circuit and subsequently, very accurate control valve regulation. Due to the compact design of the valve it is easily installed in both domestic and commercial heating and cooling systems. Industrial Valves

Frese The Frese SIGMA Compact is an externally adjustable dynamic balancing valve that provides simple, accurate and reliable flow limitation and isolation in heating and cooling systems. The Frese SIGMA Compact can be used in both heating and cooling systems for the effective distribution of flow in various sections of the system. The Frese SIGMA Compact can be used instead of traditional double regulating valves and can be installed in both variable flow systems and constant flow systems. The Frese SIGMA Compact can be set to the required position easily by using the hand wheel to limit the flow rate in certain parts of a system, eradicating overflows and the unnecessary wastage of energy. The internal differential pressure control function of the Frese SIGMA Compact ensures that the set flow rate is limited irrespective of fluctuations in the differential pressure of the system. Once the valve has been set to the desired flow rate, the hand wheel can be locked in position. From this locked position, the valve can be fully closed for isolation purposes and easily re-opened back to the required set point. Industrial Valves

Frese This solution - which is a world’s first - allows our customers to reduce some of the complexity in 4-pipe heating and cooling systems by minimizing the number of required valve components. By integrating the differential pressure controller in the valve , you have fewer connection points, which minimizes potential leakage problems, and with just one actuator you only need one data point to the building’s BMS. Frese COMBIFLOW 6-way is designed to cover a wide flow range. This simplifies the selection process, since a limited product range can cover a wide variety of needs. In addition, an extremely high flow capability has made it possible to downsize the valve dimension, further contributing to the valve ’s compact design. A low flow version is also available The energy saving capabilities of our patented OPTIMA Compact are also found in the 6-way solution. Additionally, the COMBIFLOW 6-way has shown the lowest pressure loss known in the market, resulting in significant pump energy savings. Industrial Valves

Frese With 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 is also available in a Veriflow-series. This has an additional P/T plug which allows for both flow measurement and verification of minimum differential pressure across the valve . This is the first pressure independent control valve (PICV) on the market to integrate both functionalities in the original valve housing without add-ons and additional space requirements.

Frese This dynamic balancing valve is manufactured in stainless steel in order to ensure the highest possible resistance against corrosion in domestic hot water, but it is based on familiar and extremely well-proven technology. It is, in fact, identical to one of Frese’s classic valves - The ALPHA - which has been used in heating and cooling systems all over the world for several years. Only the material is different - the core features and benefits remain exactly the same. The dynamic properties of ALPHA Sanitary ensure balance throughout the circulation system, regardless of fluctuating pressure conditions and water temperature. Once the valve has been installed with the correct cartridge for the system in question, you will at all times achieve the exact flow required to compensate for heat loss in the pipes. This way there will always be quick access to hot water even at outlying tapping points, so consumers will not be left waiting. Flow control is particularly relevant since many district heating providers are attempting to run their distribution systems at lower temperatures. This may pose a challenge for thermostatic circulation control, while ALPHA Sanitary is in no way affected by this development. Because ALPHA Sanitary performs its balancing tasks with no regard for water temperature, this valve is ideal for thermal disinfection in domestic hot water systems, since this process can be accomplished with no disruption of normal operation.

Frese Frese strainers are particularly designed and manufactured in order to provide maximum protection of the pipeline equipment against particles and other impurities. They are necessary in all fluid, steam and non-flammable gas systems where the presence of dirt could result in high operating, maintenance and replacement costs. The fluid enters the Frese strainer and passes into the interior of a cylindrical screen. While the fluid passes through the screen, all particles larger than the screen mesh are trapped in the screen. When the filter is removed from the strainer, it acts as a container for the accumulated impurities. The Frese strainers can perform in both horizontal and vertical installations provided that the direction of flow, as marked on the strainer, is always respected and that the filter, for vertical pipes, is situated downwards.
