Danfoss 013G-1246 Limitation Pins

The Danfoss 013G-1246 Limitation Pins are critical mechanical components designed for specific radiator valve stroke limitation. Engineered for compatibility with RA 2000 series operators and standard thermostatic radiator valves (TRV), these pins allow technicians to establish precise temperature range locking and limiting. By inserting these pins into the integrated scale of any Danfoss RA 2990 or RA 2940 sensor, you can effectively prevent occupants from adjusting temperature settings beyond calibrated parameters. This 10-pack of TRV security pins is essential for optimizing hydronic heating efficiency and maintaining system balance in multi-unit residential or commercial environments. Utilizing these radiator valve stop pins ensures that the set point remains within a desired deadband, reducing excessive energy consumption while protecting the sensitive bellows within the operator from manual over-rotation or tampering.

• Enables precise HVAC temperature range limiting for increased energy savings across large-scale facility installations.
• Provides TRV tampering protection, ensuring that balance and flow rates remain consistent with design specifications.
• Seamless integration with Danfoss RA 2000 radiator sensors, offering a secure mechanical lock without requiring specialized tools.
• Robust construction designed to withstand repeated thermal cycling and manual strain on the control head.

How do you limit a Danfoss radiator valve temperature range using these pins?
To limit the range, locate the small holes on the underside of the sensor dial. Set the dial to the desired maximum or minimum setting, then insert the Danfoss limitation pins into the corresponding slots to physically stop the dial rotation.

Are these pins compatible with older RAVE or RAV series valves?
These 013G-1246 pins are specifically engineered for the Danfoss RA 2000 series. While some older sensors share similar pin configurations, we recommend using these exclusively with the RA range to ensure a secure mechanical fit.

Can these be removed if the system needs to be recalibrated?
Yes, these pins can be extracted using a small screwdriver or needle-nose pliers, allowing a technician to reset the radiator valve lock mechanism for seasonal adjustments or system re-balancing.
