SS316   Safety valve intruction :    the best extra-pressure protection device takes care of press equipments, container and on-line pipe. when mediums pressure rises over the allowed pressure , safety valve will automaticaly open and fully discharge to protectthe equipment from pressure going on rising and will automatically close when the pressure lowers to the setting pressure .   The valve bonnet of sealed safety valve prevents dustand foreign matters from invading. meanwhile protect toxic combustible media from overflowing . the valve bonnet of open safety valve can favor the spring seat in lowering temperature inside of . it is mainly used for the pipeline and container with steam medium . the safety valve with a radiator is suitable for the medium with a temperature over 350 °c.   The safety valve with lever , it makes use of open manually when the media pressure over 75% of setting pressure .   Full lift safety valve opening heiht is more than one fourth times of the flow diameter . it has an advantage of discharging greatly . low lift safety valve valve opening height is between one twentith to one fortiegh times of the flow diameter.   Structural of Safety Valve •Closed Spring loaded low lift •Closed spring loaded full lift •Open spring loaded full lift with a lever . •Open spring loaded low lift with a lever . •fully lift with radiator . •Twin spring loaded low lift .
