Protect Your HVAC/R Systems
with an Energy-Efficient
Solution
Upgrading Electronic Expansion
Valves (EEV) is one of the best ways to
improve overall system performance
and reliability.
Electronic Expansion Valves also
help significantly improve electrical
efficiency when implemented with EC
fans and smart controllers.
With a wide range of valves designed to
control and protect HVAC/R systems,
Emerson Network Power is addressing
the need to enhance systems that
function under strict operating
conditions.
Upgrade Benefits
�Optimized control of refrigerant flow
�Energy cost reductions
�Compatibility with third-party units
Optimize Your Critical Systems
Emerson Electronic Expansion Valves (EEV) are designed for modulating
the control of refrigerant circuits with high speed and high precision.
Able to adapt to unexpected load variations and large fluctuations in
refrigerant pressure, these valves ensure stable operating conditions even
at partial load, and consequently optimize the control of refrigerant flow.
The EEV provides superior performance compared to a Thermostatic
Expansion Valve (TXV) due to:
�Precise flow control
�Positioning time
As such, Electronic Expansion Valves are a recommended improvement to
ensure the longevity of your cooling units.

Operating at Continuously Stable Conditions
Improve Your Performance Levels
Emerson Network Power Electronic Expansion Valves
improve direct expansion evaporator units. These valves are
controlled by a driver that precisely monitors the opening
and closing of the valve, allowing it to operate independently
of oscillating temperatures in an efficient manner. Electronic
Expansion Valves not only save on energy but also enhance
system performance by adapting to changing seasonal
conditions. The benefits of these valves lie in their reliable
characteristics, such as:
The replacement of the traditional thermostatic valve (TXV)
with an Electronic Expansion Valve is always performed
by highly trained and authorized Emerson Network Power
engineers. Replacement is performed using a stand-alone
valve independent of the control boards and can therefore
be applied to third-party cooling units.
�Boosts refrigerating performance
�Ensures compressor longevity
�Increases coil performance, reducing the need to
superheat (SH)
�Adapts to environmental temperature changes
�Protects from anomalies typical of TXV valves
�Increases overall system reliability
From a Traditional Method to an Innovative
Approach
Emerson Electronic Expansion Valves operate at minimum
possible condensing pressure to reduce compressor usage.
Due to this, energy is saved under all operating conditions,
therefore improving refrigerating performance. Electronic
Expansion Valve technology extends compressor lifetime,
delivers optimal functionality, increases efficiency and
reduces anomalies to increase the reliability of customer
products.
Regardless of the external environment, the evaporator will
operate at optimal conditions. Electronic Expansion Valves
also ensure high precision even at low flow rates and minimize
superheating (SH), thus improving refrigeration cycle
efficiency. The smooth operation of the Electronic Expansion
Valve minimizes superheat (SH) variations with a stand-alone
universal controller regardless of temperature conditions.
