45kg cylinder with withdrawal valve
45kg cylinder without withdrawal valve and female coupling valve may cause cold burn to users. In case of leaking, it will expand about 250 times when converted from liquid to gaseous status which can lead to fire and explosion.   
Therefore, 45kg cylinder with withdrawal valve must meet following requirements:
  • Cylinder valve is manufactured under ACME standard (self-sealed function)
  • Female coupling valve is manufactured under ACME standard (self-sealed function)
  • There is automatically flow blocked valve.
