safety Precautions
To ensure that the valve is installed in a safe manner, please
adhere to the following precautions before removal or
disassembly of any valve.
1. There is a possibility of pressurized media build
up behind the valve liner. Wear suitable protective
equipment for the fluid involved when removing a
valve from the pipeline.
2. Depressurize and bleed the line on both sides of the
valve before removing the valve.
3. 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.
4. Remove or install the valve with the disc in the closed
position.
5. Never attempt to adjust the disc in the seat while the
valve is pressurized.
