This valve is used for the safety of various pressure devices such as boiler. tank and piping.
It automatically operates and discharges fluid when the pressure of valve inlet increases and reaches to the specified value.
When the pressure is decreased to the specified value, it is automatically closed.
It is installed in ship boiler, economizer, air tank and steam/air/liquid line to quickly carry out pressure escape by popping at overload of equipment and pipes.
It can be used for both compressible fluid and non-compressible fluid.
