Sample interview questions: Can you explain your knowledge of different types of control valves used in hydronic systems and their functions?
Sample answer:
As a professional Hydronic Technician, I possess extensive knowledge of various control valves used in hydronic systems and their specific functions. These valves play a crucial role in regulating the flow and temperature of the water within the system, ensuring optimal performance and efficiency.
One common type of control valve used in hydronic systems is the globe valve. This valve is designed to control the flow of water by adjusting the position of a disc or plug in relation to the seat. It offers good throttling capabilities and is often used for precise flow control in applications such as balancing the system or regulating temperature.
Another commonly used control valve is the ball valve. This valve features a spherical disc with a hole in the center that allows for full or partial flow control. It is typically used for on/off applications rather than precise flow control. Ball valves are known for their durability and ability to handle high-pressure applications.
Thermostatic radiator valves (TRVs) are another type of control valve commonly found in hydronic systems. These valves are installed on individual radiators and allow the user to control the temperature in each room independently. TRVs use a thermostatic element to sense the room temperature and adjust the flow of water accordingly. This helps to optimize energy consumption and provide personalized comfo… Read full answer
