SS-264 Valve
September 2021
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
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.
Note
Standard graphite packing is composed of all conductive graphite ribbon packing. Alternate shaft‐to‐valve body bonding is
available for hazardous service areas where the standard packing is not sufficient to bond the shaft to the valve.
1. If the valve is to be stored before installation, protect the buttweld ends and keep the valve body cavity dry and free
of foreign material.
2. The valve is normally shipped as part of a control valve assembly, with an actuator mounted on the valve. If the
valve and actuator have been purchased separately or if the actuator has been removed, mount the actuator
according to the Actuator Mounting section.
3. Standard flow direction is forward flow, spherical face of the ball is upstream.
4. Install the valve in a horizontal pipeline with the drive shaft in the vertical position.
5. The actuator is counterclockwise to open with the shaft in a vertical orientation as shown in figure 1. If necessary,
refer to the appropriate actuator instruction manual for actuator installation and adjustment procedures.
CAUTION
Ensure the valve and adjacent pipelines are free of foreign material that could damage the valve seating surfaces.
6. Be certain the valve and adjacent pipelines are free of any foreign material that could damage the valve sealing
surfaces.
7. Be sure the pipelines are in line with each other.
8. Use accepted pipeline piping and welding practices when installing the valve in the pipeline.
9. Connect pressure lines to the actuator.
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.
10. Verify that gap "A", in figure 4, is closed before pressurizing the pipeline.
