Removing Valve from Pipeline

To remove the entire valve assembly from the pipeline, follow these steps.

This valve is a pressure vessel. Failure to release pipeline pressure may result in

personal injury and/or flow system damage. Completely release pipeline pressure

before removing the actuator from the valve or removing the valve from the pipeline.

1. Relieve pipeline pressure and drain portion of system where valve is located.

2. Close the valve.

Moving parts from accidental operation of power actuator can cause personal injury

or equipment damage. Disconnect and lock out power to actuator before servicing.

3. If the actuator is powered, disconnect and lock out the pneumatic, hydraulic, or electrical power

to prevent accidental operation of the actuator.

4. Support the valve assembly, then remove the flange bolts.

5. Remove the valve from the pipeline.

Stroke the valve between the fully open and fully closed positions to verify that the valve and actuator

are functioning properly.

Operate the valve as under normal conditions, taking care to bring the plug to the position required by

the particular emergency condition.

Length of service for parts subject to wear is dependent on service conditions.
