1、  low lift safety valve contain simple structure、good sealing、correct open pressure、great ability of emission、small pressure difference、convenient adjustment

2、  nozzle-type valve seat: Laval nozzle-type valve seat, steam go through exit, reach sound speed, large coefficient of emission, sealing surface of valve seat using tungsten carbide cobalt chromium, anti-erosion wear, long using life

3、  thermal resilient disc: thermal resilient structure, using the small deformation of media pressure, improve the sealing ability, overcome the phenomenon of pre-vent. Sealing surface use Laser Hardening technology, improved the hardness、wear resistance、impact resistance

4、  adjusting nut: by adjusting regulation nut, adjust the compression of spring, make the valve easy and quick to get correct regulation pressure

5、  back pressure adjustment bush: auxiliary institutions adjust back pressure of disc, by adjustment of back pressure adjustment bush, can get suitable re-seating pressure, when adjust up, make back pressure of valve get down. When adjust down, make back pressure of valve get up.
