Reduced Diameter Exhaust Directly Buried (Long) Welding Ball Valve
FQ361F gas release ball valve is the introduction of foreign advanced design technology and equipment research and development into a new type of energy-saving cut-off gas valve. Whether the valve is in the open or closed position, the upstream and downstream pressure can discharge the internal pressure through the release valve, to protect the equipment from damage caused by a sharp rise in pressure.

Product Features:
1, with the release device, switch flexible, small torque.
2, the whole welded, there will be no external leakage phenomenon.
3. It is composed of pipes, with sufficient strength, low price, beautiful appearance and convenient construction.
4, ball valve welding can be directly buried in the ground, do not need to build a high large valve well, only need to set up a small shallow well on the ground, greatly saving construction costs and engineering time.

Working principle:
FQ361F gas release ball valve is a kind of gas ball valve with release, including a ball valve body, in the valve body of the switch connector connected with a long core column, long core column includes a long core cylinder, coat with a protective tube; A release unit device is arranged in the pipeline controlled by the ball valve body, which includes a release base through the pipeline, a release pipe placed on the release base, the release pipe is arranged at the top end of the release valve, and through the support to make the release unit device and the long core column fixed each other, in fact, easy to use, convenient opening and closing, conducive to the detection of the pipeline.
