3. Product Overview
The Danfoss 013G8250 is a non-electric zone valve operator designed for precise temperature control in heating systems. It features a valve-mounted sensor and a dial for setting the desired temperature range.
Figure 1: Danfoss 013G8250 Non-Electric Zone Valve Operator. This image shows the white cylindrical operator with a numbered dial (1-5) and the Danfoss logo on top. The lower part is grey, revealing the connection points for the valve.
Key Features:
- Non-electric operation.
- Valve-mounted sensor for direct temperature sensing.
- Adjustable temperature set range: 45°F to 82°F (7°C to 28°C).
- Durable construction.
4. Installation
The Danfoss 013G8250 is designed for straightforward installation onto compatible zone valves. Ensure the heating system is depressurized and cooled before proceeding.
Installation Steps:
- Prepare the Valve: Ensure the zone valve is clean and free from debris.
- Mount the Operator: Align the valve operator with the valve body. The operator typically screws onto the valve or uses a clip mechanism. Refer to the specific valve's instructions for precise mounting details.
- Secure Connection: Hand-tighten the operator onto the valve until secure. Do not overtighten.
- Verify Fit: Confirm that the operator is firmly attached and does not wobble.
Note: This operator is non-electric and does not require electrical wiring. Its function is purely mechanical, responding to ambient temperature changes around the valve sensor.
5. Setup
The setup process involves setting the desired temperature range using the integrated dial.
Setting the Temperature:
- Locate the numbered dial on the top of the valve operator.
- Rotate the dial to align the desired temperature setting with the indicator mark. The temperature range is approximately 45°F to 82°F (7°C to 28°C).
- Lower numbers typically correspond to lower temperatures, and higher numbers to higher temperatures. Adjust gradually to find your preferred setting.
6. Operating Instructions
Once installed and set, the Danfoss 013G8250 operates automatically based on the ambient temperature around its sensor. It will open or close the zone valve to maintain the set temperature.
Normal Operation:
- The operator will sense the temperature and adjust the valve position without external power.
- If the area around the sensor falls below the set temperature, the valve will open to allow heating fluid to circulate.
- If the area around the sensor rises above the set temperature, the valve will close to restrict heating fluid flow.
Regularly check the temperature in the controlled zone to ensure the desired comfort level is maintained. Adjust the dial as needed for seasonal changes or personal preference.
7. Maintenance
The Danfoss 013G8250 Non-Electric Zone Valve Operator requires minimal maintenance to ensure optimal performance.
Recommended Maintenance:
- Cleaning: Periodically wipe the exterior of the operator with a soft, dry cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
- Inspection: Annually inspect the operator for any signs of physical damage or loose connections.
- Sensor Area: Ensure the area around the valve-mounted sensor is clear and not obstructed by furniture or other objects that could interfere with accurate temperature sensing.
