600lb triple eccentric butterfly valve with gear box

1. During the use of the Metal seat Butterfly Valve, it should always be kept clean. The transmission thread must be lubricated regularly. When the failure is found, the use should be stopped to find out the cause of the cause.
2. The bolt of the filler cover should be tightened evenly and should not be pressed into a crooked state, so as not to hinder the movement of the valve stem or cause leakage.
3. During installation, the Metal seat Butterfly Valve can be directly installed on the pipeline according to the connection. Under normal circumstances, it can be installed in any position of the pipeline, but it needs to be convenient for maintenance. Note that the direction of the deeper valve medium flow should be flowing upwards under the vertex valve, and the lifting valve can only be installed horizontally.
4. When the stable butterfly valve is used, it is only open or fully closed. It is not allowed to adjust the flow of flow, so as not to be eroded and accelerate the wear. There is an inverted sealing device in the Gate Valve and the upper thread truncation valve. The hand wheel rotates to the top position to tighten, which can prevent the medium from leaking from the filler.
5. Apply a hand wheel when it is turned on and off when the butterfly valve is turned on. Do not use leverage or other tools to avoid damaging the valve parts. The hand wheel rotates the clockwise to turn off, otherwise it is turned on.
6. Before installation, carefully check the pressure of the valve logo, whether the diameter meets the requirements of the use, eliminates the defects caused by the transportation process, and eliminates the dirt of the valve parts.
7. The long -term storage valve should be checked regularly. The exposed processing surface must be kept clean and clearing the dirt. When storage, the Ball Valve should be blocked at both ends and in the open state. Store neatly in a ventilated and dry place, and strictly prohibit the stacking or open -air storage.
