SAFETY PRECAUTIONS
To avoid possible injury to personnel or damage to valve
parts, WARNING and CAUTION notes must be strictly
adhered to. Modifying this product, substituting nonfac tory
parts, or using maintenance procedures other than outlined
could drastically affect performance, be hazardous to per-
sonnel and equipment, and may void existing warranties.
1. WARNING: Standard industry safety practices must be
adhered to when working on this, or any other, process
control product. Specifically, personal protective and lift-
ing devices must be used as warranted.
2. Always completely remove the valve from service before
attempting any maintenance on the valve.
3. Depressurize and bleed the line on both sides of the valve
before removing the valve.
4. Check nameplate before installation to ensure that the
valve is not installed in systems where service conditions
exceed those for which the valve was designed.
5. Install or remove the valve with the disc in the closed
position.
