Installation; Actuator Removal - Emerson Baumann 51000 Instruction Manual

Instruction Manual
D103365X012
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
Note
Whenever a gasket seal is disturbed by removing or shifting gasketed parts, install a new gasket during reassembly. This provides a
good gasket seal because the used gasket may not seal properly.
WARNING
Avoid personal injury or property damage by thoroughly cleaning the line of all dirt, welding chips, scale, oil or grease, and
other foreign material. Failure to do so could result in damage to the seating and sealing surfaces of the valve and result in
damage to the valve and release of process materials.

Installation

1. Before installing the valve in the pipeline, thoroughly clean the line of all dirt, welding chips, scale, oil or grease, and
other foreign material.
2. Install the valve so the controlled fluid will flow through the valve body in the direction indicated by the arrow.
3. A three-valve bypass permits removal of the control valve from the line without shutting down the system.
4. In case of a heat-insulated installation, insulate the valve body only, not the bonnet.

Actuator Removal

Refer to figures 2, 3, 7, and 8.
1. For air to open actuators, lift actuator travel with air to lessen tension on the upper clamp nut (key 10).
Note
For air-to-close, this is NOT required
2. Gently tap the upper clamp nut (key 10). With slight downward pressure on top of the actuator, unscrew the upper
clamp nut (key 10) completely.
3. The Baumann 16 actuator assembly must be unscrewed from the stem adapter (key 26).
