Valve for Portable LPG Container

The present invention relates to a valve for a portable LPG container, and relates to a portable LPG container valve which is compact and lightweight and easy to carry.

Large-capacity LPG containers for home use can be filled and used through "LPG container suppliers". Overseas, the use of portable LPG gas (butane gas / propane gas) containers is activated, and since they are small, they are easily transported and are used at nearby marts.

In Korea, similar to overseas, a system will be introduced that allows consumers to take LPG containers directly to retail stores such as hypermarkets to fill gas or purchase gas-filled containers, without ordering LPG delivery over the phone. It is a prospect.

In addition, in order to reduce environmental pollution due to the development of the leisure industry, disposable butane containers can be recharged and LPG containers can be recharged only for camping.

In this way, LPG can be purchased by consumers directly, so that LPG can be used at a lower cost by reducing logistics costs, as well as creating new demand for outdoor and leisure products as well as conventional cooking and heating, and LPG in accordance with the city gas diffusion policy. It is expected to be a turning point for expanding the survival base of the industry.
