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 ac-
tuator. The Mark 40 is supplied with a float 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 com-
ments:
Make the installation of the valve so that the float (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 posi-
tion. 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 prop-
erly seated on the body (1) and tighten the yoke screw.
Engage the lever in the stem clevis slot and replace the
spring pin.
The float (34) can be adjusted up or down by loosening
the nut (25) and adjusting the float to the desired posi-
tion.
Start Up
Follow the start-up procedure outlined in the Mark 70
