AMOT product story
Edited by the Engineeringtalk editorial team
Oct 25, 2002
Amot Controls has redesigned and significantly enhanced its G Valve three-way temperature control valve.
Amot Controls has redesigned and significantly enhanced its G Valve three-way temperature control valve, making it more economical and compact while also reducing unit weight and installation costs, and at the same time upgrading performance with a 70% increase in flow capability.
A new enhanced control system has also been introduced to further improve this valve.
It comprises a new PID process controller incorporating temperature dead band, remote output alarms as standard and logic outputs to drive 25A solid state relays having significantly higher performance than standard relays.
These SSRs provide excellent transient performance and switching life while also eliminating the arcing associated with traditional relays thanks to their zero volt switching.
A temperature sensor is also included.
The Amot G Valve offers rapid and accurate regulation of fluid temperatures to 100C with a maximum flow rate of 3000m3/h, which is 70% higher than previous versions.
It has a high flow rate with low pressure drop in comparison with other valves of equivalent size used for the same applications.
It is the most compact unit on the market, being 50% smaller in height than typical competitor valves for greater flexibility of piping arrangements, and can be mounted in any orientation.
Valve ports are configurable to meet application requirements.
Three types of control system are available: electric, pneumatic or electropneumatic.
The valves are ideally suited for both mixing and diverting applications, and are typically employed for fluid temperature control in large diesel and gas engines.
