Models 764W, 766W, and 768W are double
actuator controls. Each control is available
with a wide variety of switches. These units
are long welded chambers with nominal body
diameters of 4 to 8. The long welded steel
chamber totally encloses the solid graphite
d i s p l a c e r ( S . S . D i s p l a c e r O p t i o n ) .
Connections are 1 NPT (Flanged Option).
These units are sized to meet your specific
gravity and switching differential needs. W
chambers are also used for interface service
and when a stainless steel displacer or special
body length is required.
Pressure and temperature rating for these controls is
150 to 1500 psig at 500º F. Special materials of
construction available on request.
The standard specific gravity setting of the liquid
is specified on Table A (reverse side). If the
specific gravity of the liquid increases, the
switching differential will decrease. If the specific
gravity of the liquid decreases, the switching
differential will increase. Consult the factory with
the application if the specific gravity of the liquid
varies more than 0.1 from the standard specific
gravity setting.
