Instruction Manual TBX Valve D103172X012 May 2014 Servicing WARNING Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance operations: D Do not remove the actuator from the valve while the valve is still pressurized. D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury. - Page 9 5 for proper orientation. Any uneven marks around the circumference of the ring or any flattening of the ring shape at its outside diameter are indications of wear and require replacement. Contact your Emerson Process Management sales office for Bore Seal ring replacement.

Page 10: Nozzle Maintenance And Replacement
During regularly scheduled maintenance, visually inspect the nozzles for wear and blockage. Your local Emerson Service Center can help to determine the extent of weld fatigue and the correct course of action. Poor performing nozzles or nozzle failure is typically caused by wear, corrosion, erosion, and/or blockage. - Page 11 Instruction Manual TBX Valve D103172X012 May 2014 1. OPTIONAL: Figure 3 shows the spray pattern that will need to be present during operation of the AF nozzles. Testing can be performed by attaching the existing or an alternate, similar pressure, water line to the spray water input connection.
