Frese ALPHA HCR
Flow Limiting Valve
The Frese ALPHA HCR (High Corrosion Resistant) Valves are particularly designed and manufactured for automatic balancing in Marine, Industrial, Oil and Gas applications.
The Frese ALPHA HCR Cartridges - the third generation cartridges - are an integral part of the Frese ALPHA HCR Valve limiting the flow at the specified level even under fluctuating pressure conditions.
The patented design of these cartridges introduces a interchangeable orifice plate for design flexibility and a resistant diaphragm for high accuracy operation.
The high quality alloy ensures a long lifecycle and low maintenance in arduous applications such as seawater.
Available in sizes DN50 to DN450, 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
- Sizes from DN50 to DN450
- 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 as an option. Other certificates on request.
- Heat treatment acc. to 02747 Part 2#4 a+b
- Pressure test acc. to EN12266
