DeZURIK

G-Series Handwheel and Chainwheel Actuators

Description

These instructions cover adjustments and maintenance for a DeZURIK G-Series handwheel or

chainwheel actuator. Two sizes, G12 and G16, are available. See Figure 1 to identify which unit you

have.

This actuator can be furnished with either cast iron or ductile iron gears.

The ductile iron gear is necessary for submerged or buried service valves or when a 2"

operating nut is installed on the input shaft. Breakage of the gear teeth will occur if cast

iron gears are torqued above 200 ft-lb's.

Cast Iron & Ductile Iron are similar in appearance: To determine if the gear material is ductile

iron, remove the cover as described in the ACTUATOR DISASSEMBLY Section. G12 & G16

gears have "M199" cast in raised letters on either the top or under side of the web between the

hub and the teeth, removal of the gear is necessary to see the marking. If there is no "M199"

on the gear, the material is cast iron.
