1. Before installation, carefully check the various standards of stainless steel elbows, whether the diameter meets the use requirements, eliminate the defects caused by the transportation process, and eliminate the dirt of stainless steel elbows, make preparations, and be ready.

2. During installation, the stainless steel 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 needs to be easy to operate and repair. Note that the flow direction of the cut-off stainless steel elbow medium should be from the bottom of the longitudinal valve disc to the bottom, and the stainless steel elbow can only be installed horizontally.

3. When installing stainless steel elbows, pay attention to the sealing to prevent leakage and affect the normal operation of the pipeline. The bolts of the packing gland of the stainless steel elbow valve should be tightened evenly and should not be pressed into a crooked state to avoid bumping, hindering the movement of the valve stem, or causing leakage.

4. When using the ball valve, stop valve, and gate valve of the stainless steel elbow, it is only fully opened or fully closed, and it is not allowed to adjust the flow to avoid erosion of the sealing surface and accelerated wear. There is an inverted sealing device in the gate valve and the upper threaded stop valve. Turn the handwheel to the upper position and tighten it to prevent the medium from leaking from the packing.

5. When using a handwheel for stainless steel elbows, do not use levers or other tools to avoid damaging the valve parts. Turn the handwheel clockwise to close, and vice versa to open.
