Jordan Valve Mark 40/46 Series – Float/Lever Operated Valve - Manual (Page 2)

in any direction on the valve body, in 60º increments, by
removing the yoke bolts (23), and loosening the locknut
(28) and rotating the actuator assembly to the desired
position. If, however, the actuator is to be rotated more
than 60º, remove the spring pin (26) from the steam
clevis (27) and remove the lever (31) from the slot in the
stem clevis. This will allow the actuator to rotate without
rotating the stem clevis on the stem (15), which changes
the seat adjustment. After the actuator is in the proper
position, engage the lever in the stem clevis and replace
the spring pin. Replace the yoke bolts and tighten the
lock nut.
The float (38) can be adjusted up or down by loosening
the screw in the pipe clamp (35) and adjusting the float
to the desired position.
Maintenance
Follow the maintenance procedures and cautions in the
Mark 711 I&M for valve seat disassembly and reassembly.
Replacing Packing or Replacing Stem and Disc Pin
Remove the valve seat from the line. See cautions 1.
in Mark 711 I&M before removing the valve from
the line.
Remove the yoke bolts (23), remove the spring pin
2.
(26) from the stem clevis (27), and lift the actuator
assembly off of the valve body. Remove the stem
clevis (27) and locknut from the stem (15).
Remove the seats following instructions and cau-
3.
tions in the Mark 711 I&M “Valve Seat” section.
Remove the two nuts (22), the packing flange (20),
4.
and the packing follower (19).
Loosen the locknut (14) and unscrew the disc pin
5.
(13) from the stem (15). Carefully remove the stem.
Remove the packing (18), packing retainer (17), and
6.
packing spring (16).
Clean all parts, including the packing bore, with
7.
solvent.
Reassemble using new packing set and/or new
8.
stem and/or disc pin in reverse order.
Adjust seats per “Seat Adjustment” section below.
9.
Seat Adjustment
Remove the valve from the line. See cautions in 1.
Mark 711 I&M before removing the valve from the
line.
The float arm (37) may be removed from the lever
2.
by loosening the screw in the pipe clamp (35) to
facilitate maintenance. The lever (31) must remain
assembled to the valve.
For Float Rises to Open Valve
3. : raise one end of
the lever (31) until it stops against the adjusting
screw (29). For Float Drops to Open Valve: lower
the end of the lever (31) until it stops against the
spring pin.
With the lever in the proper position of 3A or 3B,
4.
Seat Adjustment
Remove the valve from the line. 1.
For Float Rises to Open Valve: Lift the end of the 2.
lever (24) until it stops against the spring pin (21).
For Float Drops to Open Valve: push the end of
the lever (24) down until it stops against the travel
bushing (23).
With the lever in the position of 2A or 2B the seats
3.
should be full open, and the orifices should be in
perfect alignment.
If the seats are not in perfect alignment, remove
4.
the spring pin (21) from the stem clevis (22) and
remove the lever (24) from the slot in the stem
clevis. Rotate the stem clevis in 180º increments,
checking alignment each 180º, until proper align-
ment is attained.
Reassemble actuator. Recheck seat alignment and
5.
replace valve in the line.
Changing Valve Action
Follow the procedure outlined in the Mark 70 I&M sheet.
Troubleshooting
Leakage or insufficient flow:
Valve seats may be out of adjustment. Check and 
readjust if necessary.
Foreign material may be on seats. Clean the seats.

Float will not rise or drop:
Binding of seats, stem or linkage. Clean parts that 
are binding.
Excessive pressure drop: reduce pressure with

pressure regulating valve (available from Jordan
Valve) or use longer level and/or larger float.
2-1/2” through 6” Sizes
