Pulse Valves as parts of Pilot-Operated Safety Valves (POSV)

These safety devices are intended for provision of safe operation of the equipment and electric power plant systems by means of protection against overpressure of the working medium higher than the allowed value.

The safety devices are automatically activated and, when opening, they discharge the working medium surplus from the site protected into the atmosphere. The safety devices are represented by pilot-operated safety valves (POSV) composed of a pressure safety valve and a pulse valve.
