1) Butane gas cartridges are filled with flammable liquefied gas. We attached a spring type safety valve to release the cartridge's vaporized gas, focusing on usersafety.
2) The safety valve helps users avoid damage from an accidental fire or explosion while using gas appliances with our company's butane gas cartridges.
3) The valve operates when the canister's pressure is increased by any external factor, such as fire. Through the safety hole, vaporized gas will be released to maintain the canister's normal pressure. By this process, the canister can be ready for reuse after the pressure is returned to normal.
4) Hwasan's safety valve product has been confirmed through "Research of butane gas cartridge with safety device" by the Institute of KGS R&D.
