do not require maintenance and their operation is silent. After connecting the control signal to the drive, the temperature of the heating element increases and thus causes the expansion of the solid medium.

This expansion is translated into linear movement of the valve stem. The valve starts to open after preheating the element, which takes approximately 1.5 minutes, if the heating element is connected from a cold state (room temperature) and the maximum stroke is reached after another approx.
