VG7000 Series Bronze Control Valves Installation Instructions

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, andAir 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.

VG7000 Series Bronze Control Valves Installation Instructions

Dimensions

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.

VG7000 Series Bronze Control Valves Installation Instructions

Pre-servicing Details

Before servicing a VG7000 Series Bronze Control

Valve, isolate or disconnect the pneumatic supply or

electricalpowertotheactuatorand note the following:

Valve Removal Details

In addition to observing general mounting guidelines

and National Code Standards, be sure to note the

following before removing a valve from a piping

system:

• Allow hot water or steam systems to cool down

thoroughly before proceeding.

• Drain the piping system to provide a pressure-free

work environment.

• Vent all piping systems that are used in conjunction

with corrosive or aggressive fluids.

• Be sure all work is performed by qualified

personnel only.

Risk of Electric Shock.

Disconnect or isolate all power supplies before

making electrical connections. More than one

disconnection or isolation 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.

Risque de décharge électrique.

Débrancher ou isoler toute alimentation avant de

réaliser un branchement électrique. Plusieurs

isolations et débranchements sont peut-être

nécessaires pour -couper entièrement l'alimentation

de l'équipement. Tout contact avec des composants

conducteurs de tensions dangereuses risque

d'entraîner une décharge électrique et de provoquer

des blessures graves, voire mortelles.

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.

Risque de blessure.

Couper l'alimentation en liquide et évacuer la

pression présente dans la conduite avant toute

intervention sur la vanne. Les liquides à l'intérieur des

conduites peuvent être sous pression et la libération

soudaine de liquide sous pression risque de

provoquer des blessures graves.

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.

Risque de dégâts matériels.

Ne pas mettre le système sous tension avant d'avoir

vérifié tous les raccords de câblage. Des fils formant

un court-circuit ou connectés de façon incorrecte

risquent d'endommager irrémédiablement

l'équipement.

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.

This product can expose you to chemicals

including lead, which is known to the State

of California to cause cancer, birth defects,

or other reproductive harm. For more infor-

mation, go to www.P65Warnings.ca.gov.

This product is made of copper alloy, which

contains lead. The product is therefore not

to be used on drinking water.
