Return temperature limiter FJVR, temperature range 10-80°C 003L1070

Return temperature limiter – precise control of thermal comfort

This return temperature limiter, type FJVR, is a reliable solution for automatic regulation of the water temperature returning from radiators, fan coil units, and underfloor heating loops. Its task is to maintain the optimal temperature in the installation, which translates into user comfort and energy efficiency of the heating system. This is particularly important in systems with a circulation pump, where a stable return temperature affects the proper operation of the entire system.

Functionality and application

The FJVR limiter is a direct-acting regulator, designed for two-pipe installations with a pump. It can also be used in ventilation systems to ensure a minimum flow through the heat exchanger. Thanks to the possibility of locking and limiting the adjustment range, it provides precise temperature control and prevents undesirable fluctuations. The valve has a nickel-plated body, which increases its corrosion resistance and extends its service life.

Key features and benefits

• Precise regulation: Adjustment range of 10-80°C allows you to adjust the temperature to individual needs and the specifics of the installation.
• Overheating protection: Automatically limits the return temperature, protecting the heating system components from damage.
• Versatility: Can be used in both traditional heating installations and underfloor heating systems.
• Easy installation: The valve can be mounted in any position, maintaining the flow direction.
• Durability: Nickel-plated body provides corrosion resistance and long service life.
• Locking option: Protects against accidental change of settings by unauthorized persons.
• Compatibility: Can be used with Danfoss RA2000 thermostatic heads (FHV-A included).

The FJVR limiter is an ideal solution for both professional installers and end-users looking for a reliable and effective way to control the temperature in their heating system. It allows for optimization of installation operation, reduction of energy costs and increased thermal comfort in the rooms. The valve is compatible with various types of pipes and Danfoss fittings, which facilitates its integration with the existing infrastructure. Additionally, the possibility of replacing the restrictor without the need to drain the installation significantly simplifies the servicing of the device.
