BEFORE INSTALLING AND SAVE IT FOR FUTURE USE
General Features
The VG1000 Control Valve serves to regulate the flow of water, water/glycol solutions
and saturated steam in heating, ventilation, and air-conditioning systems.
There are, however, differences in water composition. Normal tap water can usually be
used without further preparation, as long as it remains in a closed system and it has,
after a while, chemically "settled". When, however, due to water loss the system
is constantly being refilled, then the water must be treated.
Recommendations are contained in guideline VDI 2035. Usage of other fluids is
possible but must be confirmed by the manufacture.
Selection and adaptation of materials has been made in compliance with current
EN regulations. Mechanical and flow characteristics are in conformance with
EN 12516-3 and EN 60534-2-4 standards.

Installation

To ensure trouble free function of the control valves the pipe immediately upstream
of the valve should be straight for the length of at least 2x DN and the pipe immediately
downstream straight for the length at least 6x DN.
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.
Mounting the Actuator
Figure 5: Correct mounting position of VG1000 Series Valves
with Actuators
Install VG1000 Series Ball Valves with the actuator at or above the centerline of the
horizontal piping.
IMPORTANT: In steam applications, install the valve with the stem horizontal to the
piping. Failure to follow these guidelines may shorten the life of the actuator.
When mounting the actuator in the field, before installing the actuator, use an adjustable
wrench to manually rotate the valve stem several times. This rotation breaks the torque
that may have built up during long-term storage.

Figure 7: VG1805 Series 3-Way Ball Valve (Port B Connected to Port C)
On models with the flow-characterizing disk, the disk is located in Port A. Port A must be
the inlet. On three way models, use Port A as the coil inlet and Port B as the bypass inlet.
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, a steam pipe, or other
heat source may overheat it.
Contact your local Johnson Controls representative for compatibility concerns before
using VG1000 Series Ball Valves to control the flow of fluids other than those outlined
in the Technical Specifications table at the end of this document.
For more detailed installation information, refer to the Actuator Installation instructions.

Valve Removal
In addition to general mounting guidelines and National Control Standards the following
points should be observed:
• Pressure free piping system
• Cooled fluid
• Drained piping system
• With corrosive or aggressive fluids the piping system should be vented
• Work to be performed by qualified personnel only
Servicing the Actuator or Piping System
For conversion or service, the actuator mounting procedure should follow the actuator
installation instruction.
When servicing the electric actuator or the piping system:
• Disconnect the power supply to the actuator
• Relieve the pressure in the piping system
Location of valve data
The technical data:
• Item Code
• Kvs
• Max. Fluid temperature
• Test Pressure
• Manufacturing date code (Lyyww)
are written onto the brass tag attached to the valve.
IMPORTANT: Use copper conductors only. Make all wiring connections in accordance
with local, national, and regional regulations. Do not exceed the actuator's electrical
ratings.
WARNING: Risk of Electrical Shock. Disconnect the power supply
before making electrical connections. Contact with components
carrying hazardous voltage can cause electrical shock and may result
in severe personal injury or death.
WARNING: 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.
IMPORTANT: Do not attempt to manually rotate the drive shaft while the actuator is
installed without first releasing the actuator gears. Manually rotating the drive shaft
without releasing the actuator gears may result in permanent damage to the actuator.
IMPORTANT: These Valves are intended to control saturated steam, hot water, and
chilled water flow under normal equipment operating conditions. Where failure or
malfunction of the Valve could lead to personal injury or property damage to the
controlled equipment or other property, additional precautions must be designed into
the system. Incorporate and maintain other devices such as supervisory or alarm
systems or safety or limit controls intended to warn of, or protect against, failure or
malfunction of the Valve.
