Description
The Z500 severe service ball valve is a split body bolted design, full or reduced port, with a blowout proof shaft. It can
be lever operated, gear operated, or actuated. The Z500 severe service ball valve line is a simplistic two-piece floating
ball design with integral metal seat meant to provide tight metal seating shutoff in high temperature, high pressure,
corrosive, and erosive applications across all industries.
Specifications
Specifications for these valves are shown in table 1.

Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed
where service conditions could exceed either the valve body rating or the mating pipe flange joint rating. To avoid such
injury or damage, provide a relief valve for overpressure protection as required by government or accepted industry codes
and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
WARNING
When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,
pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve
materials with process media rests solely with the purchaser and end‐user. To avoid possible personal injury and because
some valve/trim material combinations are limited in their pressure drop and temperature ranges, do not apply any other
conditions to the valve without first contacting your Emerson sales office
or Local Business Partner.
WARNING
The valve drive shaft is not necessarily grounded to the pipeline when installed. Personal injury or property damage could
result from an explosion caused by a discharge of static electricity from valve components if the process fluid or the
atmosphere around the valve is flammable. If the atmosphere around the valve or the process fluid is flammable,
electrically bond the drive shaft to the valve.
WARNING
Personal injury could result from packing leakage. Valve packing was tightened before shipment; however the packing
might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any
additional measures that must be taken to protect against process media.
When a valve is shipped bare shaft:
a. Valve is shipped in the open position with exposed shaft
b. Valve will include two shaft keys.
When a valve is shipped with mounting kit only:
a. Valve will ship in the in open position
b. Valve will have the mounting finger-tight to the valve
c. Customer shall ensure proper mounting of the actuator

Instruction Manual
D103803X012
d. Customer shall ensure valve shaft has not been pushed or forced down into the valve
e. Customer shall ensure no binding occurs when mounting the actuator
i. Customer shall ensure the correct alignment is done when mounting the actuator
ii. No hammering or forcing down of the shaft adapter is allowed
f. Customer shall ensure all bolts are torqued down appropriately
g. Customer shall ensure the actuator mounting surface is completely flush with the mounting bracket. For
additional information on actuator mounting, refer to the Actuator Mounting section in this instruction manual
on page 13.
h. Customer shall ensure the mounting can allow for or can accommodate expansion of the shaft or adapter at high
temperatures. See table 7.
When a valve is shipped with actuator:
a. Valve will be shipped in the required fail position
b. All bolting will be torqued as required
c. Emerson recommends that the customer not remove the actuator for final installation in the line
1. Inspect the valve prior to installation into the piping system to ensure there is no shipping damage. End protectors
and shipping materials must be removed to allow a complete inspection.
2. Inspect the actuator, if included, for damage and then cycle the valve with the actuator from open (the normal
shipping position) to closed to open to ensure proper functioning.
CAUTION
Make sure the valve is installed in the correct orientation. Put the high pressure side (body side) on the upstream side. The
arrow on the valve should point from the high pressure to low pressure side when the valve is closed. The valve could be
damaged if installed incorrectly.
Weld End Valves
WARNING
Emerson Automation Solutions is not responsible for improper installation or inspection of any valve which falls outside the
criteria presented in this instruction manual. Requests for additional information on unique situations should be directed
to your Emerson sales office
CAUTION
or Local Business Partner.
Weld fill between the valve and pipe should never be used to correct for improper pipe installation length or misalignment.
Additional welding beyond what is required may cause the valve to reach higher temperatures and have a larger
heat-affected zone, which can cause permanent damage to the valve or its components.
For additional information, refer to ASME Boiler and Pressure Vessel Code Section IX.
