Emerson Clarkson ZP300 Installation And Maintenance Instructions Manual

CLARKSON KNIFE GATE VALVE MODEL ZP3OO

INSTALLATION AND MAINTENANCE INSTRUCTIONS

Before installation these instructions must be fully read and understood

GENERAL INFORMATION

The Clarkson ZP300 knife gate valve is
designed to meet extremely rugged and
challenging requirements of expansible fluid
applications in the oil sands processes.

Please take note of specific installation tags
provided with each ZP300 series valve.

1. Compliance to ASME B16.34 Class 300,
Valves-Flanged, Threaded, and Welding End
and MSS SP 135 (Long Face-to-Face).

2. Bi-directional valve, no special concerns
in relation to direction of flow are required
when installing the valve.

COMPLIANCE LABEL

3. Mating line flanges must be properly
aligned. Slip-on or weld flanges can be used.
Never try to make up for misaligned pipe
flanges by the line bolting.

4. Flange fasteners should be tightened in a
uniform manner using a cross-pattern to
prevent distortion of the valve.

5.

Pipe supports and/or expansion joints should
be used to minimize pipe loads on valves.
ZP300 valves are suitable for use in either
vertical or horizontal lines. If installation is
other than vertical, additional support will be
required for cylinder actuated valves.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

INITIAL INSPECTION

1. Examine entire valve and report any damage
or discrepancies immediately.

2. Accessories, if any, including solenoids,
limit switches, positioners, etc., are tested
for functionality prior to shipment. Examine
carefully for damage which may occur
during shipment.

3. Operators: standard manual hand wheels
may be shipped loose for field installation.

4. Packing assembly: the packing gland bolts

should be checked and adjusted to obtain
a first time packing seal. Packing gland
nuts may become slightly loose when valve
is shipped. Field adjustment is expected
and desired. (Figure 1. Tighten just enough
to stop any leakage. Overtightening may
increase valve operating torque and shorten
packing life).

FIGURE 1

It is necessary to use a pipe wrench or large
crescent wrench to properly tighten the
hand wheel retaining nut. Be sure to fully
tighten.

BOLTING AND INSTALLATION INSTRUCTIONS

ZP300 standard flange configuration is
“flanged” where port flange mounting holes are
drilled and tapped. Flange mounting holes in
chest area are limited to a depth of 1 x flange
bolt diameter. It is recommended that studs
be used on all flange mounting holes in chest
area.

WARNING

Care must be taken when installing studs or bolts
in tapped flange holes in chest area to prevent
damage to internal wall profile.

NOTE

Optional through bolting configurations are also
available.

ZP300 Series valves are design to suit flanges
compliant to ASME B16.5 and B16.47, and
gaskets designed to ASME VIII-1 Appendix
2, and ASME B16.20 and B16.21. Torque on
Flange bolt should not exceed values shown in
Table 1.

NOTES

1. Maximum torque should not be exceeded to insure threaded flange holes in valve body are not damaged.

2. The recommended bolt length assumes; final gasket Thickness = .125", Min F436 Flatwasher Thickness 1x
bolt diameter thread depth, and common heavy hex bolt lengths. Use the below equation to calculate flange
bolt length per your application. It is strongly recommended stud to be used to achieve maximum thread
engagement length.
