VG7000 Series Bronze Control Valves Installation Instructions 1

Refer to the QuickLIT website for the most up-to-date version of this document.

Applications

VG7000 Series Bronze Control Valves are primarily

designed to regulate the flow of water and steam in

response to the demand of a controller in Heating,

Ventilating, and Air Conditioning (HVAC) systems.

Contact the local Johnson Controls® representative for

compatibility concerns before using the VG7000 Series

Bronze Control Valves Technical Specifications

table at

the end of this document.

These installation instructions conform to the relevant

and valid European Norm (EN) safety standards, as

well as the current laws and regulations of the

European Union. Qualified personnel are required for

the proper application of these installation instructions.

Qualified personnel are trained in the installation,

mounting, commissioning, operation, and servicing of

pneumatically and electrically actuated VG7000 Series

Bronze Control Valves; they include trainers and

instructors who have the following responsibilities:

• ensure adherence to regional and international

ordinances and requirements

• teach safety standards

• enforce adequate facility safety and protective

operation

• instruct first aid

Location of Valve Data

Each VG7000 Series Bronze Control Valve shipped

from the factory includes a brass tag chained to the

valve bonnet. The tag features technical data about the

valve, including:

• code number of the valve

• flow coefficient Cv of the valve

• maximum allowable fluid temperature of the

controlled media

• manufacturing date code of the valve (as

illustrated in Figure 1)

Installation

Pre-installation Details

Before installing a VG7000 Series Bronze Control

Valves, note the following:

• Be sure to mount the valve in an upright position, in

a conveniently accessible location.

• Protect the electric actuator from dripping water

that could enter the actuator housing and damage

the mechanism or motor.

• Do not cover the actuator with insulating material.

• Allow sufficient clearance to remove the actuator

(see Figure 2, Table 1, and Table 2).

• Pipe the valve with the flow in the direction of the

arrow on the valve body, so that the plug seats

against the flow.

• Wire all electrically actuated valve assemblies in

accordance with applicable electrical code

requirements. Input lines to the actuator must be

wired correctly for the valve to move in the proper

direction.

IMPORTANT: The VG7000 Series Bronze Control

Valves are intended to control saturated steam, hot

water, and chilled water flow under normal

equipment operating conditions. Where failure or

malfunction of the VG7000 Series Valve could lead

to personal injury or property damage to the

controlled equipment or other property, additional

precautions must be designed into the control

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 VG7000 Series Valve.

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.
