    Spring-loaded pressure relief valve is one of the main types of pressure relief valves in which the closing force or spring force is applied by a spiral spring. In a spring-loaded pressure relief valve, the closing force or spring force is applied by a helical spring that is compressed by an adjusting screw. ATO offers 1/2 inch/3/4 inch/1 inch/1 1/4 inch/1 1/2 inch/2 inch pressure relief valves for selection. A spring loaded relief valve is used in many applications to protect the over pressurization of vessels, pipes and containers.
