The valve is no leakage in both direction in shut off position. When installing, leave the butterfly valve partly open. Make sure there is enough distance between pipeline flanges to place the valve. Don’t add sealing gaskets between the flange and the valve.
Insert bolts into flange and tighten opposing nuts sequentially. Make sure that valve is aligned with the flange.
Fully open the valve. Make sure that the disc is centered and there is no jam between the valve and the disc.
Pipeline flange standard should be consistent with the butterfly valve flange standard. Make sure that the pipeline flange has enough surface for sealing. It is necessary to ensure that the butterfly valve plate does not collide with the inner diameter of the pipe during the opening process.
Avoid oil and impurity in the pipeline.
The butterfly valve must not be installed at the corner of the pipeline.
Don’t use the valve as a tool to increase the space between the pipeline flanges.
The installation and commissioning of the valve actuator are completed in the factory. Commissioning and dismounting should not be done on site.
Connect the terminal according to the terminal number as shown on the wiring diagram.
Recommend to install a protective cover against rain, if the motorized butterfly valve is installed outdoors.
