What is claimed is: 1. A valve assembly, comprising: a vessel or conduit, said vessel or conduit including a process on an interior thereof; and a valve, said valve including: a valve body; an internal cavity formed in said valve body; an orifice formed in said valve body, said orifice being in com
What is claimed is: 1. A valve assembly, comprising: a vessel or conduit, said vessel or conduit including a process on an interior thereof; and a valve, said valve including: a valve body; an internal cavity formed in said valve body; an orifice formed in said valve body, said orifice being in communication with said internal cavity and said interior of said vessel or conduit; a sealing tip for opening and closing said orifice; and an outlet formed in said valve body, said outlet being in communication with said internal cavity, wherein at least one of said valve body, said sealing tip and said vessel or conduit includes at least one space formed therein between said interior of said vessel or conduit and said internal cavity, said at least one space including an active or passive thermal insulation forming at least a partial barrier to the flow of heat between said internal cavity and said interior of said vessel or conduit. 2. The valve assembly according to claim 1, wherein said thermal insulation is a passive thermal insulation, said passive thermal insulation including a thermal insulation material at least partly filling said at least one space. 3. The valve assembly according to claim 1, wherein said thermal insulation is a passive thermal insulation, said passive thermal insulation including said at least one space being empty. 4. The valve assembly according to claim 1, wherein said thermal insulation is an active thermal insulation, said active thermal insulation being at least one thermalelectric unit. 5. The valve assembly according to claim 1, wherein said thermal insulation is an active thermal insulation, said active thermal insulation including a connection to a source of flowable material for flow of the flowable material through said at least one space, said flowable material being of a predetermined temperature to control a temperature of said at least one space. 6. The valve assembly according to claim 5, wherein said connection includes an inlet and an outlet in communication with said at least one space, said inlet of said at least one space being in communication with said source of flowable material. 7. The valve assembly according to claim 1, wherein said vessel or conduit includes a flange or ferrule for mounting said valve body thereto, said at least one space being formed in said flange or ferrule. 8. The valve assembly according to claim 1, wherein there are a plurality of said at least one space forming at least two layers between said internal cavity of said valve body and said interior of said vessel or conduit. 9. The valve assembly according to claim 8, wherein at least one of said plurality of spaces is an active thermal insulation and at least one other of said plurality of spaces is a passive thermal insulation. 10. The valve assembly according to claim 1, wherein said at least one space is formed within said sealing tip of said valve. 11. The valve assembly according to claim 1, wherein said at least one space is formed within said valve body. 12. The valve according to claim 1, wherein there are a plurality of said at least one space forming at least two layers between said internal cavity of said valve body and the interior of the vessel or conduit. 13. The valve according to claim 12, wherein at least one of said plurality of spaces is an active thermal insulation and at least one other of said plurality of spaces is a passive thermal insulation. 14. The valve according to claim 1, wherein said at least one space is formed within said sealing tip of said valve. 15. The valve according to claim 1, wherein said at least one space is formed within said valve body. 16. A valve for a vessel or conduit, the vessel or conduit for containing a process in an interior thereof, said valve comprising: a valve body; an internal cavity formed in said valve body; an orifice formed in said valve body, said orifice being in communication with said internal cavity and an interior of said vessel or conduit; a sealing tip for opening and closing said orifice; and an outlet formed in said valve body, said outlet being in communication with said internal cavity, wherein at least one of said valve body and said sealing tip includes at least one space formed therein between the interior of the vessel or conduit and said internal cavity, said at least one space including an active or passive thermal insulation forming at least a partial barrier to the flow of heat between said internal cavity and the interior of the vessel or conduit. 17. The valve according to claim 16, wherein said thermal insulation is a passive thermal insulation, said passive thermal insulation including a thermal insulation material at least partly filling said at least one space. 18. The valve according to claim 16, wherein said thermal insulation is a passive thermal insulation, said passive thermal insulation including said at least one space being empty. 19. The valve according to claim 16, wherein said thermal insulation is an active thermal insulation, said active thermal insulation being at least one thermalelectric unit. 20. The valve according to claim 16, wherein said thermal insulation is an active thermal insulation, said active thermal insulation including a connection to a source of flowable material for flow of the flowable material through said at least one space, said flowable material being of a predetermined temperature to control a temperature of said at least one space. 21. The valve according to claim 20, wherein said connection includes an inlet and an outlet in communication with said at least one space, said inlet of said at least one space being in communication with said source of flowable material.
