Description
The G Valve and its supporting equipment are designed for the control of fluid
temperature by ‘diverting’ or ‘mixing’ control techniques.
The valves can be used for fresh and sea water, most lubricating oils and other
liquids.
The compact construction of the G Valve enables unobstructed, full-bore flow,
thus minimising pressure losses.
2.1.1
Features
The G Valve system has the following main features:
•
Any direction of rotation.
•
Any rotor-port configuration (most models).
•
Compact construction.
•
Low pressure drop.
•
High accuracy (
±
1
°
C or better).
•
Mount in any position.
•
Manual override.
•
Temperature up to 100
°
C (212
°
F).
•
Local valve position indication.
