Danfoss 013G-8042 Straight Valve

The Danfoss 013G-8042 is a heavy-duty 1/2 inch solder union straight radiator valve engineered for two-pipe low-pressure steam and hot water hydronic systems. This RA-C series valve is designed for high-performance flow control, featuring a nickel-plated brass body that resists corrosion in demanding environments. It utilizes a durable EPDM O-ring seal to prevent leaks and ensure long-term system integrity. Contractors rely on the straight pattern configuration for streamlined installations in tight mechanical spaces where a direct connection is required. This valve is fully compatible with Danfoss RA2000 thermostatic operators, allowing for precise temperature regulation and improved energy efficiency. The solder union tailpiece provides a secure, sweat-connection point, maintaining a rigid seal under thermal expansion. Whether you are performing a retrofit or a new build, this valve ensures balanced hydronic flow and consistent heat distribution across the radiator circuit.

• High Flow Capacity: Optimized for low-pressure steam and hot water applications requiring consistent Cv values.
• Rugged Construction: Nickel-plated brass housing ensures durability against aggressive system fluids.
• Field Serviceable: The internal packing gland can be serviced or replaced while the system is under pressure, reducing downtime.
• Precise Throttling: Provides linear flow characteristics for accurate hydronic balancing.
• Seamless Integration: Standardized RA2000 connection fits a wide range of Danfoss snap-action thermostatic sensors.

Is the Danfoss 013G-8042 compatible with steam systems?
Yes, this valve is rated for low-pressure steam systems as well as standard hot water hydronic circuits.

What type of connection does this valve use?
It features a 1/2" solder (sweat) union inlet for a permanent, leak-proof connection to copper piping.

Can I adjust the flow pre-setting on this valve?
Yes, this model allows for manual pre-setting of the flow rate to balance the system before the thermostatic head is installed.
