Product Overview

VG7000 Series Bronze Control Valves Product Bulletin 21
M100 Series Electric Actuators
The M100 Series Actuators operate on 24 VAC, and
are available for on-off/floating or proportional control.
A rack and pinion drive mechanism provides the linear
movement. The rack assembly contains a spring that
maintains valve closeoff when compressed by
overtravel of the actuator. On three-way valves, this
seating force is applied on both the up and the down
stroke. The actuator has an adjustable travel limit that
provides the desired overtravel. On loss of power, the
spring return actuator will return to its normal position.
Refer to the M100 Series Motor Actuator Product
Bulletin (LIT-2681059P) and/or the VG7000 Valve
Linkage for M100 Series Motor Actuators Technical
Bulletin (LIT-977355) in the for specifications and
available options.
Installation and Servicing
It is recommended that the VG7000 Series Valves be
mounted in an upright position in a conveniently
accessible location. Sufficient clearance must be
allowed for actuator removal. (Refer to the Dimensions
section for more details.) The valve must be piped with
the flow in the direction indicated by the arrow, so that
the plug seats against the flow.
On electrically actuated valve assemblies, input lines to
the actuator must be wired correctly for the valve to
move in the proper direction.
Note: VG7000 Series Valves should not be used for
fluid service other than those indicated in the Technical
Specifications section.
Before servicing a VG7000 Series Bronze Control
Valve, please isolate or disconnect the pneumatic
supply or electrical power to the actuator, allow
sufficient clearance for actuator removal from the
valve, and note the following:
IMPORTANT: Protect the actuator from dripping
water, condensation, and other moisture. Water or
moisture could result in an electrical short, which
may damage or affect the operation of the actuator.
IMPORTANT: Do not cover the actuator with
thermal insulating material. High ambient
temperatures may damage the actuator, and a hot
water pipe, steam pipe, or other heat source may
overheat it.
IMPORTANT: Take care to prevent foreign material
such as weld slag, thread burrs, metal chips, and
scale from entering the piping system. This debris
can damage or severely impede the operation of the
valve by embedding itself in the seats, scoring the
valve, and ultimately resulting in seat leakage. If the
debris becomes embedded in the seats, subsequent
flushing and filtering of the piping system with the
valve installed does not remedy the problem.

WARNING: Risk of Electric Shock.
Disconnect each of multiple power
supplies before making electrical
connections. More than one disconnect
may be required to completely de
energize equipment. Contact with
components carrying hazardous voltage
can cause electric shock and may result
in severe personal injury or death.
IMPORTANT: Make all wiring connections in
accordance with local, national, and regional
regulations. Do not exceed the electrical ratings of
the VG7000 Series Bronze Control Valve.
!
CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
!
WARNING: Risk of Personal Injury.
Shut off the liquid supply and relieve
pressure in the line before servicing the
valve. Contents of liquid lines could be
under pressure and the release of liquid
under pressure may cause severe
personal injury.
