Applications
Thermal safety valves protect against excessive temperatures in liquid applications, especially in long pipes exposed to the environment. They are vital in closed vessels, water heating systems, and the cooling return side of heat exchangers. These valves are also crucial for pumps recirculating water to mitigate heat risks. In transport pipelines or storage areas prone to obstructions, thermal relief valves are necessary to prevent pressure increases from solar heating or heat tracing.
Working principle of thermal safety valve
The Thermal Relief Valve (TRV) functions like a pressure relief valve. Although labeled a thermal safety valve, it operates primarily based on pressure increases. Normally, the TRV stays closed due to spring force. When fluid expansion pressure exceeds this force, the valve opens. As pressure decreases, the spring force closes the valve, ensuring effective operation.
Importance of thermal safety valve
Valvesonly Europe durable Thermal Safety valve manufacturer are essential for protecting equipment from damage due to pressure increases caused by rising temperatures. In closed-loop systems, restricted fluid expansion can lead to significant pressure spikes, risking malfunctions, leaks, or explosions. These valves provide an automatic solution to these issues, improving safety and operational efficiency.
