Parts Identification

Caution
1) The valve disc is set in the position indicated by the solid lines in Fig. 1 prior to
shipment from the factory. If the valve is opened or closed after unpacking, it
must be reset in this position before installation. Failure to do so may result in
damage to the surface of the valve seat during handling and installation.
2) The valve must not be dropped or come in contact with other objects, as the
sealing surfaces of the disc and or valve seat may be damaged.
3) Care must be used during piping installation to ensure that pipe or flanges are
properly aligned so that the valve disc does not come in contact with them.
Misalignment as shown in Fig. 2 will result in damage to the valve.
4) The installed valve must never be opened or closed when foreign matter such
as sand is present in the pipeline.
