During installation, the concealed stem gate valve can be directly installed on the pipeline according to the connection method, and installed according to the used position. Under normal circumstances, it can be installed at any position in the pipeline, but it needs easy-to-operate maintenance. Note that the medium flow direction of the cut-off dark-stem gate valve should be upwards from below the longitudinal valve flap, and the dark-stem gate valve can only be installed horizontally. The concealed stem gate valve should pay attention to the tightness during installation to prevent leakage and affect the normal operation of the pipeline.
The concealed stem gate valve should be kept clean during use, and the transmission thread must be regularly lubricated. When a fault is found, it should be stopped immediately to find out the cause and clear the fault.
Concealed stem gate valve should use a hand wheel, do not use levers or other tools to avoid damaging the valve parts. Turn the handwheel clockwise to close, and vice versa to open. The dark stem gate valve should be used reasonably to ensure the correct use method and means.
