JRGUMAT compact blending water facility, without by-pass

The JRGUMAT thermoblending valve is an open architecture, proportionallyregulating three-way mixer. The blended water temperature is transferred to the thermostat A. This compares it with the set-point value. If the blended water temperature does not correspond to the setpoint value, a volume change takes place in the thermostat A. This causes the valve slide B to be regulated through the pin C, until the blended water temperature corresponds to the set-point value.

The fitting can mix the water used only as it is drawn. Functions such as back flow prevention, blocking or adjustment of the circulation flow volume cannot be performed by the ® JRGUMAT thermoblending valve. The model to be used will depend on the installation diagrams
