1-11-2 Slide Gate Metering Assemblies
Air operated slide gates are provided to meter the majority of pellet
ingredients on the SGB blender.
Important! The metering range assumes
1
/8” diameter free-flowing plastic
pellets weighing approximately 35 lbs./cu. ft. This is meant to be
an approximate sizing recommendation and can vary with
different bulk density resins, pellet configuration, etc.
A stroke limiter (included) can be installed on the metering gates to
limit their travel. This device decreases the stroke of the gate and
reduces the metering orifice of the valve. The unique diamond gate
provides a square opening at any stroke length, providing more
consistent flow from smaller valve openings than conventional slide
gates. This stroke limiter may be necessary to accurately meter low
percentage ingredients.
The air cylinders operating the slide gate are rugged, stainless steel
cylinders designed for industrial use.

WARNING!
Slide gates create a pinch-point hazard.
Always disconnect and lockout all electrical power and
pneumatic (i.e. compressed air) sources prior to
servicing or cleaning any blender, including all SGB
Series models. Failure to do so may result in serious
injury.
The unique Sterling diamond gate provides a constant
aspect opening that remains square regardless of the
stroke length of the cylinder. This design provides a wider
cross sectional opening when approaching a closed
position, and provides better flow of plastic pellets out of
the opening.
