Models 764F, 766F and 768F are double actuator
flanged chamber mounted units.
Switching differentials for standard specific gravity
settings are shown in Table A on reverse side.
Maximum specific gravity for these controls is 1.4
The lower switching point of the lower actuator is
8-1.4” below the centerline of the horizontal
connection of the chamber. Switching gap at
standard specific gravity will be set at 4” unless
otherwise specified, but may vary from a minimum
of 2” on all models to a maximum of 4” on the 4” model
and maximum of 6” on the 6” and 8” models.
These models are available in various pressure
ranges shown in Table Below. The desired pressure rating
of the controls is included in the figure number.
These models have dual actuators and are available
with graphite displacers.
