Valve internal leakage is a common fault of natural gas pipeline valve. Therefore, it is important to have fault analysis and implementation of solutions. In the fault analysis, the general method is to make the valve in full open or closed state, and detect the discharge of the valve blow down nozzle to confirm if there is air leakage. If the gas can be eliminated clean, it proves that the air tightness is good; If the gas has been discharged, the valve has been shown to have internal leakage, it should be treated accordingly.

In the valve body, it has a channel when the valve inspection, which can only be in the state of closed. This is because this kind of valve in the full open, and the channel is also in the open state where it cannot judge the sealing of the valve.

ZJCLV valves can also be used in natural gas. ZJCLV valves are of good quality and thickness, and rarely fail. For more information, click on the website: www.clvvalve.com.
