Danfoss 013G-0140 Connector

The Danfoss 013G-0140 is a specialized one-pipe steam radiator valve body engineered for precise temperature regulation in low-pressure hydronic systems. This nickel-plated RA2000 1-PS valve features a 1/8" NPT threaded connection and is specifically designed to house an air vent and thermostatic operator. By utilizing an integrated vacuum breaker, the assembly ensures that air can return to the radiator during the cooling cycle, preventing the core vacuum lock common in older 1-pipe steam systems. With a maximum working pressure of 10 PSI and a temperature rating up to 250°F, this component provides the heavy-duty reliability required for both residential and commercial steam heating renovation projects. For a complete thermostatic solution, pair this body with a Danfoss RA 2000 operator to achieve modulating control and eliminate the typical "all-or-nothing" heating cycles found in traditional cast iron radiators. The angle-style design and MNPT tailpiece facilitate easy replacement of standard air vents, allowing for a 1-pipe steam thermostatic conversion without extensive repiping.

• Vacuum Breaker Integration: Prevents system vacuum formation, ensuring consistent condensate drainage and natural system aspiration.
• Precision Temperature Control: Enables thermostatic modulation on single-pipe systems when paired with RA2000 thermostatic operators.
• Durable Construction: Features a robust nickel-plated finish for corrosion resistance in harsh steam environments.
• High Compatibility: Standard 1/8" NPT connection fits most existing cast iron radiators and convectors.
• Operational Stability: Maintains system efficiency at a differential pressure range of up to 15 PSI (1 bar).

Can I use this on copper fin tube radiators?
No, the 1-PS thermostatic radiator valve assembly is not recommended for copper fin tube radiators; it is designed for free-standing radiators and cast iron convectors.

Is the air vent included with the 013G-0140?
The 013G-0140 is the valve body only. The air vent (013L8011) and thermostatic operator (013G8250) must be purchased separately to complete the assembly.

How should the thermostatic operator be installed?
For accurate sensing, the thermostatic operator must always be installed horizontally to allow room air to pass freely over the sensor.
