Installation & Maintenance Instructions for

Mark 40/46 Float/Lever Control Valves

Start Up

I&M.

Maintenance

Follow the maintenance procedures and cautions in the
Mark 70 I&M for valve seat disassembly and reassembly.

1/4” through 2” Sizes

To be used with the Mark 70 I&M

The Mark 40 Float Valve and the Mark 46 Lever Valve are
of the same construction with the exception of the ac­tuator. The Mark 40 is supplied with a oat actuator; the
Mark 46 is supplied with a lever, with a series of drilled
holes, for attachment to a customer supplied actuator.

Installation

Follow the installation procedure and cautions outlined
in the Mark 70 I&M with the following additional com­ments:

Make the installation of the valve so that the oat (or

lever) is properly positioned relative to the tank (or actua-
tor). Note that the actuator assembly can be positioned

in any direction on the valve body by loosening the yoke
screw (19) and rotating the actuator to the desired posi­tion. If, however, the actuator is to be rotated more than
90 degrees, the spring pin (21) should be removed from
the stem clevis (22) and the lever (24) removed from
the slot in the stem clevis. This will allow the actuator to
rotate without rotating the clevis pin on the stem (10),
which changes the seat adjustment. After the actuator is
in the proper position, check that the yoke (18) is prop­erly seated on the body (1) and tighten the yoke screw.
Engage the lever in the stem clevis slot and replace the
spring pin.

The oat (34) can be adjusted up or down by loosening
the nut (25) and adjusting the oat to the desired posi­tion.

Replace Stem & Disc Pin

Remove the valve seat per instructions in Mark 70 1.
I&M “Valve Seats” section.
Loosen the yoke screw (19) and rotate the actuator 2.
assembly counter-clockwise until the stem clevis
(22) screws off the stem (10). Remove the actuator
assembly.
Loosen the lock nut (9). Rotate the disc pin (8) 3.
counter-clockwise while pulling the stem (10) up.
Do not remove the stem; lift it only enough to re­move the disc pin.
Reassemble in reverse order and adjust seats per 4.
instructions in “Seat Adjustment” section.

Replace Packing

Remove the valve from the line and remove the 1.
valve seat per instruction in Mark 70 I&M “Valve
Seats” section.
Loosen the yoke screw (19) and rotate the actuator 2.
assembly counter-clockwise until the stem clevis
(22) screws of the stem (10). Remove the actuator
assembly.
Remove the two nuts (17) and lift off the packing 3.
ange (15) and packing follower (14).
Loosen the locknut (9) and rotate the stem (10) 4.
counter-clockwise to screw it out of the disc pin
(8). Remove the locknut from the stem and pull the
stem out of the body.
Remove the packing (13), packing retainer (12), and 5.
packing spring (11).
Clean all parts, including the packing bore, thor-6.
oughly with solvent.
Reassemble in reverse order and adjust seats per 7.
instruction in “Seat Adjustment “ section.

PROTECT VALVES WITH LINE STRAINERS

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 orices 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 align­ment is attained.
Reassemble actuator. Recheck seat alignment and 5.
replace valve in the line.

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 oat (38) can be adjusted up or down by loosening
the screw in the pipe clamp (35) and adjusting the oat
to the desired position.

Maintenance

Changing Valve Action

Follow the procedure outlined in the Mark 70 I&M sheet.

Troubleshooting

Leakage or insufcient ow:

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 oat.
