Danfoss 013G-8240 Operator

The Danfoss 013G-8240 is a heavy-duty RA2000 tamper proof operator engineered for commercial and institutional environments where unauthorized set-point adjustment must be eliminated. This thermostatic radiator valve operator features a specialized gas-filled sensor that ensures significantly faster response times compared to wax-filled alternatives. Designed for direct valve mounting, it maintains a precise temperature range between 45°F and 86°F (7°C to 30°C) and incorporates an integrated frost protection setting to prevent system freeze-ups during unoccupied hours. The RA2000 radiator thermostat is a North American version compatible with the full range of Danfoss RA2000 valves, including those for two-pipe hot water and low-pressure steam systems. To ensure accurate sensing, this operator must be installed horizontally to allow ambient air to pass freely over the built-in gas bellows, preventing heat-soak from the valve body or terminal unit from causing premature shutoff. This unit is the professional choice for schools, hospitals, and public facilities requiring high-accuracy RA 2000 sensor performance in a ruggedized, secure housing.

• Tamper-Resistant Security: Prevents unauthorized temperature adjustments and vandalism in public spaces using a secure, locking design.
• Fast Reaction Gas Bellows: Superior thermal response identifies room temperature changes rapidly for tighter set-point control and energy savings.
• Flexible Application: Fully compatible with Danfoss RA2000 series valves for both hot water and low-pressure steam heating systems.
• Frost Protection: Includes a dedicated setting to maintain a minimum temperature, protecting piping from freezing in cold climates.
• Mounting Precision: Features the RA-click/Allen-screw connection for a solid, mechanical bond to the valve body that resists mechanical strain.

Can this operator be installed vertically for baseboard applications?
No, for built-in sensor models like the 013G-8240, horizontal orientation is critical. Vertical installation causes the sensor to intercept rising heat from the radiator, leading to false high-temperature readings and poor performance.

What tool is required for installation and set-point locking?
The unit is secured and adjusted using a standard 2mm Allen key and specialized Danfoss limiting pins to lock the dial range or fix the set-point.

Is this compatible with older Danfoss valve bodies?
This operator uses the standard RA series connection. It is designed for modern RA2000 valves but may require an adapter for legacy 1-inch or non-RA series valve bodies.
