Safety valve is a pipeline valve designed to protect against mechanical destruction of vessels and pipelines with overpressure by automatically releasing excess liquid, vapor and gaseous media from systems and vessels with overpressure when the pressure is too high..

Safety valve classification

2. By the lifting nature of the closing element
   – proportional valves (used on incompressible fluids)
   – open-close valves
3. By the lifting height of the closing body
   – low-lifting
   – medium-lifting
   – full-lifting
4. By the way the excess fluid discharge
   – open (the working fluid is discharged into the atmosphere)
   – closed (not reaching the atmosphere)
5. By the load type on the spool
   – direct-loaded or lever-operated
   – spring
   – lever-spring
   – magnetic-spring
