Thermal Safety Valve Manufacturer in India

Specialityvalve is the best Thermal Safety Valve Manufacturer in India. A thermal safety valve is used to prevent excessive pressure in a closed system caused by the heat expansion of a liquid. When a liquid is heated, it expands, however not as much as a gas. Even if the temperature rises, the change in the liquid is not significant.

It is made to safeguard the pump and the operator when the pump is working and the discharge outlets are closed. In this case, the pump detects energy, which is turned into heat, causing the pump water to heat up. These valves are commonly used in various applications, including steam boilers, pressure vessels, and HVAC systems, to maintain the desired temperature and pressure levels within safe limits. They are responsible for maintaining the security and quality of high-temperature systems, ensuring that they operate reliably and avoid serious damage due to overheating.
