Jordan-valve Mark ED & ET Series Globe Style Control Valve User Manual download pdf

IntroductIon

Contained in this manual are installation instructions,

maintenance and parts information for the 1 through

6-inch Mark E Series, Mark ED and Mark ET Globe

Style Control Valves. Refer to the appropriate manuals

for instructions for the accompanying actuator, posi-

tioner and additional accessories.

Only trained or experienced personnel should carry

out the operation and installation of all pressure equip-

ment. If you have any questions regarding the equip-

ment, contact your Jordan Valve Controls representa-

tive.

InstallatIon

1. Before installing a Mark ED or ET Series valve

carefully inspect for damage that

may have occurred in shipment.

2. Remove all welding slag, pipe scale and any

other foreign matter by cleaning out the lines

before installation.

3. Install the valve so that the ﬂow direction arrow

on the body coincides with the actual process

ﬂow through the valve.

4. Use accepted piping practices when install-

ing the valve. Use a suitable gasket between

pipeline ﬂanges and valve body.

5. Although the control valve can be installed in

any position, the typical installation has the

actuator vertical above the body.

6. Installing a conventional 3-valve bypass

around the body will allow for continuous op-

eration during maintenance and inspection.

7. Mark E Series valve bodies are rated at 150,

300 and 600 lb. ANSI. Be sure not to install

the valve in any system where working pres-

sures are greater than those speciﬁed in the

standards.

MaIntenance

Warning:

To avoid damage to the process system or personal

injury, isolate the valve from the system and relieve

any pressure contained within prior to disassem-

bly. Disconnect any operating lines providing air

pressure, control signals or electrical power to the

actuator.

Disassembly

Except where indicated, refer to Figure 1 for part de-

scriptions used in the following procedure.

1. With the actuator disconnected and removed

from the body, remove the hex nuts, (key 15,

ﬁgure 8).

2. Remove the bonnet with the valve plug and

stem.

3. Loosen the packing ﬂange nuts (key 5, ﬁg-

ure 7) and remove the valve plug and stem

from the bonnet. If the valve stem needs

replacement, punch out the groove pin and

unscrew the stem. If the valve plug needs

replacement, a new valve plug and stem as

sembly is required.

Warning: Do not use an old stem with a new valve

plug. Using an old stem requires drilling a new hole

for the groove pin and as a result, the integrity of

the stem is weakened.

4. If desired you may disassemble the internal

parts of the bonnet. To replace the Packing,

see instructions titled “Packing Replacement”

in this manual.

Warning: The portion of the cage which is exposed

provides a guiding surface. Ensure that this sur-

face is not damaged during disassembly or mainte-

nance. If the cage is seized in the body, use a rub-

ber mallet to strike the exposed portion at varying

points around its circumference.
