INSTALLATION

1. Read the WARNING Section.
2. If there is weepage past the stem seal upon installation,
it means that valve may have been subject to wide
temperature variations in shipment. Leak tight per­
formance will be restored by a simple packing
adjustment described in the MAINTENANCE Section.
Flow through the Jamesbury Series 3000 valve can be
in either direction, but the preferred way to install the
valve is with the insert end upstream.
3. The Series 3000 is an end entry design with an internal
insert as shown in (Figure 1). The insert contains a hex
or slot drive which can be identified by looking into the
end of the valve before installation. Although the Series
3000 valve may be disassembled it is not considered
repairable. If valves with Monel® or Hastelloy C® trim
require repair, contact the factory.
