Abstract

The invention relates to a valve that contains a piston (2) linked with the valve body (8) and received in a housing (4), and a stuffing box (14) interposed between the piston (2) and the housing (4). The stuffing boxes of valves used for media having a high melting point and being operated close t o the melting point risk being damaged by so-called freezing medium due to the adhesive properties of the medium in temperature ranges below the melting point. The aim of the invention is therefore to improve such a valve with fe w constructive efforts in such a manner that the material of the stuffing box reliably works in the liquid range of the medium. To this end, the housing ( 4) is provided with a heating device (16) in the area of the stuffing box (14). The axial length of said heating device is larger than the axial length of t he stuffing box (14), and the heating device (16) axially protrudes beyond an axial end (22) of the stuffing box (14) by a predetermined length (24, 28).< /SDOAB>
