Installation instruction:

The valve is designed for using between all types of flat or raised face flange, do not use flange gaskets. For proper installation, the space between flanges must be sufficient to permit valve insertion without disturbing the rubber liner flange seal. Rotate the stem to position the disc within the body, place the valve between flanges and hand-tighten the bolts. Slowly open the valve counter clockwise to check for adequate disc clearance. Rotate the disc to 10% open position and cross tighten all bolts again check for adequate disc clearance.

Stem retaining mechanism:

The stem is retained in the body through a special Q type design when the size is under DN350mm, so the stem can be removed from the body and disc without any special tools. Only when being disassembled, the valve disc can be positioned around 135º.

Others:

According to customer requirements.
