Dear sea friends, let’s discuss whether a shut-off valve is needed in front of the natural gas vent valve
Generally speaking, to ensure the proper operation and safety of the natural gas vent valve, it is recommended to install a stop valve in front of it. Stop valves can be used to control the flow of natural gas, and they can shut off the supply of natural gas when necessary to prevent accidents. At the same time, the stop valve also facilitates the maintenance and inspection of the relief valve. Therefore, installing a shut-off valve can improve the reliability and safety of the natural gas vent valve. .
It is recommended to use a dual-valve setup for the venting pipeline: a ball valve plus a throttle-stop vent valve. The ball valve remains open at all times, while the throttle-stop vent valve is used for venting; a regular stop valve can also be used. If the seal of the end vent valve is leaking, the ball valve can be closed to allow for maintenance or replacement of the vent valve
