Frese ALPHA HCR
Dynamic Balancing Valve
The Frese ALPHA HCR (High Corrosion Resistant) Valves are particularly designed and manufactured for automatic balancing in Marine applications.
An integral part of the Frese ALPHA HCR Valve is the Frese ALPHA Flow Cartridge, whichs limits the flow to a specified level at all times, including under fluctuating pressure conditions.
The patented design of the flow cartridge introduces a interchangeable orifice plate for design flexibility and a resistant diaphragm for accuracy operation.
The Frese ALPHA HCR valve can also be installed with the Frese ALPHA HCR cartridge for other highly corrosive applications such as seawater or other marine applications.
Available in sizes DN15 to DN40. Frese ALPHA HCR valve guarantees the hydraulic balance of the system regardless pressure fluctuations.
Benefits
Design
- No requirement for balancing valves in the distribution lines and supply lines
- Less time to define the necessary equipment for a hydraulic balanced system
- No impact if the calculated distribution of pressure in the installation is not accurate
- Security that the specified flow is also the real one
Installation
- Minimized commissioning time due to automatic balancing of the system
- Cartridge solution makes flushing procedure very easy
- No need for oversized pumps and oversized control valves
- No requirements for straight diameters of pipe upstream and downstream of the valve
- Can be easily installed where space is limited
Operation
- Balancing of the system takes place automatically even under fluctuating pressure conditions
- Performance optimization
- Distribution/balancing optimization
Features
- Valve housing manufactured in RG5, NiAlBr or AISI 316 for highly corrosive applications
- P/T plugs for differential pressure verification
- Modifications & extensions of the system do not affect the hydraulic balance in the other parts of the system
- Tamper resistant cartridge independent of flow regulation errors during commissioning and operation of the system
- Self-cleaning cartridge does not allow dirt to comprosmise the accuracy of the valve
- Resistant diaphragm between the moving parts of the cartridge eliminates friction, noise and impact from water hammer
- Delivered with 3.1 certificate in accordance with EN 10204 as an option. Other certificates on request
- Pressure test according to EN12266
