“A smart device is defined as an

electronic device, generally

connected to other devices or

networks via different wireless

protocols, that can operate to

some extent interactively and

autonomously”

Disc

Advantage:Longer service life and higher

control quality

Smaller ball

Advantage:Less torque means lower actuator

costs

Form-fit spindle

Advantage:Insensitive to inferior water quality

Air bubble-tight

Advantage:Saves energy when valve is fully

closed

Energy Valve is a Characterised Control

Valve – but why use ball valve

technology ?

Characterisation

Principle

• Characterizing disc or laser cut ball

• Gentle rise, no inlet jump

• More system stabilty across the entire

control range

• Maximum quality control in the partial

load range

Effect of a decrease of the return water temp.

on COP

• Example :

Chiller: 200 tons (703 kW)

Water condenser temperatures: 29,5°/35°C

Supply temperature of chilled water Ts : 7°C

• A reduction of return temperature of chilled water can lead to a 15% drop

of the COP
