Frese SIGMA Compact
Dynamic Balancing Valve
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.
Benefits
- Easy to size and select as only the flow rate is required
- Simplified system design with the number of balancing valves being reduced
- Works as a flow limiter ensuring no overflows
- Easy to install and adjust on site
- Provides flexibility if the system is modified after the initial installation
- Simplifies the commissioning process and reduces commissioning time due to automatic balancing of the system
- High level comfort for the end-users as a result of the correct balance of the hydraulic system
- Reliable operation as a dynamic balancing valve automatically finds the hydraulic balance regardless of pressure fluctuations in the system
- Reduces the number of valves to install as no main circuit or branch balancing valves needed in the system
Features
- Easy adjustment of the flow using the lockable hand wheel
- Isolation function according to EN1349 Class IV regardless if higher pressure is on the inlet or on the outlet side of the valve
- Maximum flow position can be locked for easy reopening to pre-set flow position, after the valve has been used for isolation
- Clear setting scale located on the hand wheel
- No minimum straight pipe lengths required before or after the valve
- Built-in P/T plugs for needle system
