Danfoss 013G-8031 Angle Body

The Danfoss 013G-8031 is a 1 1/4" NPT angle pattern valve body, engineered for high-capacity performance in two-pipe hot water and low-pressure steam systems. Built with a heavy-duty nickel-plated brass body and a sturdy EPDM rubber valve disc, this RA2000 thermostatic radiator valve ensures a reliable, positive seal at differential pressures up to 15 PSI. Designed as a fixed-capacity component with a Kvs value of 2.8 m³/h, it provides stable flow regulation for large free-standing radiators and convectors. A key advantage for maintenance teams is the replaceable packing gland, which allows for servicing under pressure without requiring a system drain-down. This valve body is compatible with the full range of Danfoss RA2000 operators, making it a versatile standard for commercial and residential hydronic heating upgrades. Each unit is supplied with a protective grey cap for manual control during the construction and installation phase.

• Serviceable Under Pressure: The integrated packing gland assembly is replaceable while the system is fully operational, reducing downtime during maintenance.
• High-Temperature Durability: Rated for flow temperatures up to 250°F (120°C) and a maximum working pressure of 145 psi, ensuring longevity in demanding steam or hydronic environments.
• Precision Control: Features a 1 1/4" FNPT x MNPT union tailpiece connection for secure, leak-free installation on heavy-duty piping.
• Universal Operator Compatibility: Specifically designed to pair with RA2000 thermostatic sensors for automated, non-electric zone control.

What is the maximum differential pressure for this valve in a water system?
The Danfoss 013G-8031 is rated for a maximum differential pressure of 15 PSI for both hot water and low-pressure steam applications to ensure quiet operation and prevent valve chatter.

Does this valve body include the thermostatic sensor?
No, this is the valve body only. The RA2000 1 1/4 inch angle body must be paired with an appropriate Danfoss RA 2000 operator (sensor/dial) to function as a complete thermostatic control assembly.

Can I install this on a one-pipe steam system?
This specific model is designed for 2-pipe systems. For one-pipe steam radiators, a different valve body with a dedicated air vent port is required to ensure proper condensate drainage and air removal.
