Twin spring loaded type safety valve 
Safety valve intruction :
TANA twin spring loaded type safety valve , 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.
