Abstract. Spring-loaded self-actuating safety valves are employed as part of the overpressure protection systems in various industrial applications. In order to design and predict their performance it is required to study the valve dynamic behavior over a range of fluid and system conditions. It has been observed that certain spring-loaded

Spring-loaded Pressure-relief ValvesGenerally, the safety valves are referred to the Spring-loaded Pressure-relief valves, the most common type ( See the 

Valve closed. In a direct spring loaded safety valve the closing force or spring force is applied by a helical spring which is compressed by an adjusting screw. The spring force is transferred via

PSE spring-loaded safety relief valves are used specifically in liquid applications where a proportional characteristic is required. Above set pressure, these valves open steadily with increasing pressure ensuring only necessary capacity is relieved during opening.

The ordinary spring loaded safety valve is shown in Figure below. The valve is held closed by the helical spring whose pressure is set by the compression 

There are different safety valve types: valves with a spring-loaded mechanism, valves with balanced bellows, and pilot-operated safety valves. Each type has an advantage in a specific situation. Spring mechanism. This safety valve is the most commonly used version, called direct-acting safety valves because it is only held closed by a spring.

All safety valves used shall be constructed, installed, and maintained in accordance with the A.S.M.E. Boiler and Pressure Vessel Code, Section VIII Edition 1968. 1910.169(b) and with one or more spring-loaded safety valves. The total relieving capacity of such safety valves shall be such as to prevent pressure in the receiver from
