Danfoss 013G-8020 Straight Body Valve

The Danfoss 013G-8020 is a heavy-duty 3/4 inch straight body radiator valve designed for two-pipe low-pressure steam or hot water systems. As a core component of the Danfoss RA2000 series, this valve features a non-electric thermostatic design that provides precise temperature control and energy balancing. It utilizes a straight pattern flow configuration with a 3/4" FNPT inlet and a 3/4" MNPT union outlet, ensuring a secure, leak-proof connection in high-demand commercial or residential hydronic circuits. The valve body is constructed from nickel-plated brass to resist de-zincification and scaling, maintaining flow integrity over the system's lifespan. This model is engineered for compatibility with RA2000 operators and high-capacity thermostatic sensors, allowing for field-adjustable flow limiting. For technicians, the Danfoss 013G-8020 installation is straightforward, utilizing a standard packing gland assembly that can be serviced under pressure, minimizing system downtime during routine maintenance.

• Universal RA2000 Compatibility: Seamlessly integrates with all RA2000 thermostatic operators and electronic actuators for flexible system control.
• Durable Construction: The nickel-plated brass body provides superior corrosion resistance in both steam and hot water applications.
• Serviceable Design: The spindle packing gland can be replaced while the system is under pressure, preventing the need for a full system drain-down.
• Pressure-Independent Performance: Engineered to provide consistent radiator heat output even during fluctuating system differential pressures.
• Precise Balancing: Supports pre-setting of flow rates to ensure even heat distribution across all zones in multi-unit buildings.

Is the Danfoss 013G-8020 suitable for one-pipe steam systems?
No, this is a two-pipe radiator valve. It is designed for hydronic or low-pressure two-pipe steam systems up to 15 psig. Utilizing this in a one-pipe configuration will result in improper condensate drainage.

What is the maximum operating temperature for this valve?
This 3/4 inch straight valve is rated for a maximum water temperature of 250°F and a maximum steam pressure of 15 psig, making it ideal for high-temperature hydronic loops.

Can I install a Danfoss thermostatic head directly onto this valve?
Yes, the 013G-8020 features the standard Danfoss snap-action connection, allowing for tool-free installation of any RA2000 series thermostatic operator.
