2. During installation, the Pressed ventilation elbow can be directly installed on the pipeline according to the connection method, and installed according to the position of use. Under normal circumstances, it can be installed at any position of the pipeline, but it is necessary to facilitate the inspection of the operation. Note that the medium flow direction of the cut-off Pressed ventilation elbow should be upward from the vertical valve flap, and the Pressed ventilation elbow can only be installed horizontally. Pressed ventilation elbow should pay attention to the tightness during installation to prevent leakage and affect the normal operation of the pipeline.

3. When the ball valve, globe valve and gate valve of the Pressed ventilation elbow are used, they are only fully open or fully closed, and are not allowed to be used for flow regulation, so as to avoid erosion of the sealing surface and accelerated wear. There are reverse sealing devices in the gate valve and the upper threaded globe valve. The handwheel is turned to the uppermost position and tightened to prevent the medium from leaking from the packing.
