Radiator OptiFlow Valve

Bespoke Design

Performance & Efficiency

• Maximises heat pump performance. Engineered for low-temperature heating systems like air and ground source heat pumps. 
  
• Precise hydraulic balancing. Regulates radiator flow to optimise efficiency and performance. 
  
• More even heat distribution. Ensures consistent warmth across the whole property. 
  
• Speeds up commissioning. Visual flow control reduces setup time for installers and HVAC professionals.

Easy to Install & Use

• Integrated flow meter. See live flow rates (0.5–5L/min) without extra tools. 
  
• Clear markings with smooth adjustment. Makes balancing fast and reliable. 
  
• Compact 15mm all-in-one design. Combines a lockshield valve with the flow meter for cleaner installs. 
  
• Ideal for installers & enthusiasts. Delivers professional-grade control in a simple format. 
  

Flexible Configurations Available

• Standalone OptiFlow valve. Pair with your chosen TRV or lockshield. 
  
• OptiFlow + Danfoss RAS-C² TRV. Adds thermostatic control for precise room temperature management. 
  
• OptiFlow + Danfoss RLV-D Lockshield. Easy radiator isolation for maintenance or open-zone systems. 
  

Extra Installer Advantages

• Thermostatic option enhances comfort. Perfect for bedrooms or high solar gain rooms where temperature precision matters. 
  
• Danfoss Lockshield option supports maintenance ease. Bidirectional (Danfoss lock shield valve only) and adjustable with a standard 6mm Allen key. 

Engineered specifically for low-temperature heating systems, our all-in-one 15mm OptiFlow valve delivers precise hydraulic balancing to maximise system efficiency and decrease commissioning times. By regulating flow rate through each radiator, the valve ensures optimal heat distribution throughout the property.

It combines a lockshield valve with a visual flow meter that shows real-time flow from 0.5 to 5L/min (typical range). With clear markings and smooth adjustment, it helps you balance zones for optimal comfort and efficiency. Ideal for installers or HVAC enthusiasts wanting precise control in compact form.

The valve is available in three options:

1. Standalone OptiFlow valve to pair with a lockshield or TRV of your choice
2. OptiFlow valve with a Danfoss RAS-C² TRV
3. OptiFlow valve with a Danfodd RLV-D lock shield valve

The Danfoss RAS-C² TRV operates as a good pairing to the OptiFlow valve where further thermostatic regulation is required. This pairing would be used commonly on bedrooms (where temperature regulation is vital), rooms with high solar gain, or rooms with secondary heating sources to limit the output of the radiator.

The Danfoss RLV-D lock shield valve is used to isolate the radiator for maintenance or replacement. It is bidirectional (Danfoss lock shield valve only) and operated using a standard 6mm Allen key, ensuring simple and precise adjustment. This would be used on open zone heat pump systems where further thermostatic regulation isn't required.
