Zusammenfassung:	A valve configured to control flow of a material therethrough includes a body having a bore formed axially therethrough. The valve also includes a cooler positioned at least partially around or within the body. The cooler is configured to cool the material to below a melting point of the material to form a solid plug within the body to prevent the material from flowing therethrough. The valve also includes a heater positioned at least partially around or within the body. The heater is configured to re-heat the material to above the melting point of the material to allow the material to flow therethrough.
