Danfoss 013U-0070 Packing Gland

The Danfoss 013U-0070 Packing Gland is a critical service component engineered for Danfoss RA series valves, specifically legacy RAV and RAVL radiator valves and FJVR return temperature limiters manufactured before September 2004. As a veteran technician knows, maintaining the integrity of the stuffing box is essential for preventing slow leaks at the valve stem that can lead to system pressure loss or water damage. This valve repair part features a durable brass body and integrated EPDM O-rings, providing a high-pressure, leak-free seal without requiring a full valve body replacement. Designed for longevity in hydronic heating systems, it facilitates easy installation using a standard 10mm or 12mm wrench (depending on exact vintage). Crucially, this assembly allows for a "live" service—it can be replaced under pressure in most residential applications without the need to drain the entire heating loop, saving significant labor time on the job site. Regular replacement of the 013U0070 gland seal ensures optimal thermostatic control and smooth spindle movement.

• Direct Compatibility: Precision-fit for Danfoss RAV, RAVL, and FJVR valve bodies, ensuring a factory-standard seal.
• No-Drain Service: Engineered to be replaced while the system is under pressure, minimizing downtime and eliminating the need for air venting post-repair.
• Superior Sealing: High-grade EPDM O-rings resist mineral build-up and thermal degradation in hot water and 2-pipe low-pressure steam systems.
• Cost-Effective Maintenance: Restores functionality to older thermostatic radiator valves without the expense of cutting out and replacing the entire valve housing.

Is the 013U-0070 compatible with the newer RA 2000 series valves?
No, the 013U-0070 is specifically for older RAV and RAVL series. For newer Danfoss RA 2000 (RA-N, RA-U, RA-G) valves, you generally require the 013G0290 packing gland.

What tools are needed for the replacement?
Replacement typically requires a 10mm or 12mm open-end wrench to unscrew the old hex-head gland and torque the new one into the valve bonnet.

Can this be used on steam systems?
Yes, it is rated for use in 2-pipe low-pressure steam heating systems where RAV or RAVL bodies are installed, provided temperatures do not exceed the EPDM limit of 250°F.
