Strainer  installation instructions:

Verify the strainer to be suitable for the specifications of medium, such as maximum operating pressure, maximum operating temperature, corrosiveness and abrasiveness.
The operating temperature of the check valve is -20/+300°C
Keep the strainer in a clean environment and do not remove the protective caps until installation.

The strainer can be used in the pipeline in any position. The cover must be facing downward.

The arrow, on the strainer body, must be in the same direction of the liquid flow.
Before installation, the pipeline must be cleaned of all dirt such as sand, welding residues, etc.

The pipeline should be free of tension before installation commences.
Verify that the distance between the flanges, where the strainer will be connected, is equal to the length of the valve body.

Use suitable gaskets between strainer the strainer flanges and counter flanges.
First, mount one side of the strainer and only lightly fit the bolts. Do not fully tighten the bolts yet. Similarly, mount the other side of the strainer. Finish by uniformly tightening the bolts, to avoid twisting the strainer body, on both sides of the strainer
