A safety valve is a valve that acts as a fail-safe in a thermal-hydraulics plant. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits.
The safety valve is used to prevent inadmissible overpressures of fluid media in tanks, containers and plant sections. Generally, the set pressure is sealing 1 O-ring 1 Hood 1 Screw plug – deaeration 1 Sealing 2 Screw 1 Slotted nut 1 Clamp coupling 1 Rod 1 Pressure spring 1 Bearing 1 Disc 1 Lever 1
