TO INSTALLATION, STARTUP, AND OPERATION OF
THIS EQUIPMENT. ALSO, DO NOT DISCARD THIS
INSTRUCTION MANUAL UPON COMPLETION OF
THE INSTALLATION AS THIS MANUAL CONTAINS
INFORMATION ESSENTIAL TO THE SAFE HANDLING,
OPERATION, AND MAINTENANCE OF THE EQUIPMENT.
REGAL Series 7000 SMARTVALVES are used to AUTOMATICALLY
regulate the feed rate of a REGAL gas dispensing system. The
Models (
7001
and
7006
) covered in this manual are used
specifically for Flow Proportional Control which applies to systems
where the water flow varies but the quality of the water remains
the same. In this control scheme, a Water FLOW Meter, located
in the main water line, continuously transmits a 4-20 milliamp
signal to the SMARTVALVE indicating variations in the water
flow rate. The SMARTVALVE then responds by automatically
adjusting the chemical feed rate in direct PROPORTION to the
water flow. The Models 7001 and 7006 may be used for either
Chlorine (CL
2
) or Sulfur Dioxide (SO
2
) gas feed systems.
MODEL 7001
is used for 10 PPD (200 gm/hr)
to 500 PPD (10 kg/hr) systems.
MODEL 7006
is used for 1000 PPD (20 kg/hr)
and 2000 PPD (40 kg/hr) systems.
A) THE IMPORTANCE OF MIXING
Complete and rapid mixing of the chemical solution at the point
of application CANNOT BE OVERSTATED. Without proper
mixing, control will be erratic and unacceptable due mainly to
the chemical’s tendency to stratify (horizontally and vertically),
even around bends and sharp corners. A quick, thorough mix
will enhance the chemical contact time resulting in more
constant, stable residual readings.
Injecting the chemical solution into a full, turbulent flowing
pipeline generally provides a complete mix in a matter of
seconds and a relatively short distance (10-20 times the pipe
diameter). Also, it is very important that the chemical solution
be injected into the center one-third of the pipeline. In a
pipeline that is not flowing full, external mixing devices (static
mixers, mechanical mixers, flash mixers, propeller mixers, etc.)
MUST be used. These devices should always be located just
after the chemical injection point and, to prevent off-gassing
and corrosion, it is ESSENTIAL that the chemical solution be
injected directly into the water stream, NOT above it.
B) THE IMPORTANCE OF PROPER SIZING
OF SYSTEM COMPONENTS
Use the following guideline to properly size the system components.
1) The REGAL Gas Feed System should be sized so the
average gas feed rate falls within the middle third of the
system’s capacity (maximum feed rate).
2) The water flow meter and transmitter must be sized, or
scaled, so the maximum water flow coincides with the
maximum feed rate (capacity) of the SMARTVALVE.
C) TRANSIENT VOLTAGE SURGE SUPPRESSION
(See Drawing No. 7)
In order for automatic control systems to operate properly, the
individual components must have “clean” signals that are free
of accumulated transients and protected against electrical
power surges. Electrical surges travel along AC lines, data
lines, analog signal lines, communication lines, and virtually
any conductor they can find. A powerful surge can totally
destroy solid state circuits and their components. Therefore, it
is essential to install external power conditioning equipment
such as surge suppressors and filters. REGAL SMARTVALVES
should be protected with suppression devices placed on the
incoming AC power line and on the incoming DC analog signal
lines. The analog signal lines for flow inputs and residual
analyzer inputs should provide a voltage clamp at a maximum
of 12 volts.
(See Drawing Nos. 1 and 2)
The REGAL Models 7001 and 7006 SMARTVALVES are just
one component in a REGAL complete gas feed system.
Therefore, it is essential for all other system components to be
in proper operating condition prior to installation. If the REGAL
SMARTVALVE is being added to an existing gas feed system,
some changes to system components may be required to
ensure proper function. Refer to the Instruction Bulletin provided
with your REGAL gas feed system for more information. Also
feel free to contact your local REGAL dealer or Chlorinators
Incorporated directly.
IMPORTANT: When shipped from the factory, the REGAL
Model 7001 or 7006 SMARTVALVE will be sized to
the capacity specified by the customer at the time of
purchase. If the capacity needs to be changed for any
reason, the Valve Plug size, Remote Meter Panel, and
other system components may also need to be changed.
Consult your REGAL dealer or Chlorinators Incorporated
for further assistance.
NOTE: It is highly recommended to use exclusively REGAL
components to ensure proper, consistent function of
the system.
A) LOCATION OF COMPONENTS
(See Drawing No. 1)
The REGAL SMARTVALVE should be wall mounted at eye
level in an area where it is easily accessible and provides a
clear view for easy operation. For optimal performance, the
installation should be indoors so that temperature limitations
are not exceeded. SEE SPECIFICATIONS.
IMPORTANT: Make sure the enclosure cover is in place
and securely fastened to prevent the entry of moisture or
corrosive gases while also eliminating the possibility of
electric shock.
