Application

Smart check valve can check gas leakage of reclaimed the pipe by installing at the front side of 20A gas pipe meter when low pressure gas (LPG, LNG) of 30kPa or less.

It can be installed easily, and it can be used as alternative for inspection meter.

Horizontal installation is prohibited.

Features

 
•Possible self leakage inspection and easy installation after construction of reclaimed gas pipe
•Possible easy visual verification of the leakage of gas line that is difficult to check
•Possible verification of leakage in the environment where electronic detection is impossible such as reclaimed pipe
•Prevention of back flow of inspection liquid with back flow blocking device design
 

Usage

1. During the use of the gas, as the same as how to use general valve, use it by turning the handle of the main pipe in the direction of open <-> close.

2. During the inspection of leakage of the reclaimed gas line, close the valve of the main pipe and turn the small handle in the inspection part counterclockwise according to the open marking to check the gas leakage.

3. If gas is leaking from the reclaimed pipe, air bubble will be formed without stopping in the inspection water barrel.

4. After the gas leakage inspection, make sure to turn the inspection valve clockwise in the closing direction.
