1. A valve unit comprising:
- a valve filler which includes a phase transition material;
a chamber to receive the valve filler;
a fluid channel; and
a connection passage which is located between the chamber and the fluid channel and provides fluid communication between the chamber and the fluid channel,wherein the phase transition material melts and expands upon an application of the electromagnetic waves to the valve filler, and the valve filler is directed into the channel through the connection passage and closes the channel,which further comprises an external energy source applying electromagnetic waves to the valve filler,wherein the external energy source comprises a laser beam source irradiating a laser beam.

Abstract
Provided are a valve unit and a reaction apparatus having the valve unit. The valve unit includes a phase transition material, which melts and expands upon an application of the electromagnetic waves to the valve filler, and the valve filler is directed into the channel through the connection passage and closes the channel. The valve unit also includes heat generation particles, which are dispersed in the phase transition material and generate heat upon an application of electromagnetic wave energy.
