The electronic expansion valves of the T/S series are designed for use in air conditioning and refrigeration systems as well as in heat pumps. These valves enable automatic adjustment of the refrigerant flow rate and thus ensure optimum operating conditions, fast cooling and heating, precise temperature control and energy savings. The valves can also be used as suction line pressure regulators. These valves enable bidirectional operation to control the refrigerant flow rate in heating or cooling mode.
