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 t he process fluid is flammable,
electrically bond the drive shaft to the valve.
Note
Standard PTFE packing is composed of a partially conductive carbon-filled PTFE female adaptor with PTFE V-ring packing. Standard
graphite packing is compos ed 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 t o the valve (see the following step).
Attach the optional bonding strap assembly (key 131, figure 3) to the valve drive shaft (key 6) with the clamp (key 130,
figure 3) and connect the other end of the bonding strap assembly to the valve body with the cap screw (key 23).
1. If the valve is to be stored before installation, protect theflangematingsurfacesandkeepthevalvebodycavitydry
and free of foreign material.
2. Install a three-valve bypass around the c ontrol valve assembly if continuous operation will be necessary during
inspection and maintenance of the valve.
3. 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 and the appropriate actuator instruction manual.
4. Standard flow direction is with the seal protector ring (key 3) facing upstream.
5. Install the valve in a horizontal or vertical pipeline with the drive shaft in a horizontal position.
CAUTION
Do not allow the valve to be installed in the pipeline with the drive shaft in the vertical position because of excessive wear
to valve component parts.
6. The actuator can be right- or left-hand mounted with the shaft in a horizontal 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.
7. Be certain the valve and adjacent pipelines are free of any foreign material that could damage the valve sealing
surfaces.
8. Be sure the pipeline flanges are in line with each other.
Installing V150 and V300 Valves
1. Install the V150 and V300 valve using studs (keys 32 and 33, not shown) and nuts to connect the valve flanges to
the pipeline flanges. The seal protector ring (key 3) end of the valve requires longer line flange studs (key 32) than
standard. Do not use standard-length line flange studs for the seal protector ring end of the valve.
