Installation of your Amot-valve

AMOT temperature control valves have a wide range of applications, and can be set up both as a mixing valve and a distribution valve. The valve works by directing part of the liquid flow into another loop at a certain temperature – for example to a cooler or back to the heat source. Typical applications are temperature control of coolants, lubricating oils, water in district heating systems etc. Contact us for advice and guidance in relation to your needs, and we will find the right valve for you.

Below you will find some examples of the installation of the valves - both the self-regulating wax valves (models B, C, D, E, H, J and R) and the valves equipped with an electric or pneumatic actuator (model G).

Self-regulating thermostatic valves:

Mixing of liquid flow (mixing valve)

When an AMOT self-regulating thermostatic valve is used to mix fluid streams, port C in the example shown to the right is connected to the cold fluid stream from the cooler. Port B takes in hot fluid from the bypass line, and the fluid leaves port A and returns to the heat source. The thermostatic element ensures that the hot and cold liquids are mixed in the right ratio, so that the desired outlet temperature leaves port A.

Division of fluid flow (distribution valve)

When an AMOT self-regulating thermostatic valve is used to split a fluid flow, port C in the example on the left is connected to the cooler, and port B to the cooler bypass. The temperature is recorded in the inlet port (A), and the setting of the thermostat element determines at which temperature liquid is led via cooler or via bypass.

Valves with actuator:

Mixing of liquids

For example, lube oil temperature control is typically configured in a mixing application, where the return oil temperature is measured. The temperature is normally measured as close to the heat source as possible.

Distribution of liquid flow

When checking the coolant temperature in, for example, a petrol or diesel engine, the temperature of the liquid is sensed in the outlet from the engine. The valve sends the liquid either to a cooler or to bypass, so that the correct temperature is maintained. The temperature is normally measured directly at the outlet from the heat source.

Charge air temperature control

An intercooler is used to cool high temperature air passing from the turbocharger to an engine.

In this application, the G-valve regulates the flow of cooling water through the intercooler thereby increasing efficiency, improving performance and helping to meet today's environmental requirements.
