FIELD: mechanical engineering. SUBSTANCE: valve has rectangular-section seats pressed to each other and provided with channels and windows for passage of gas. It also includes lifting limiters and locks. Separating plates provided with recesses divided by longitudinal jumpers are positioned between adjacent seats. Longitudinal jumpers form recesses for arrangement of removable working plates of variable rigidity. Each of working plates is made as cut-off member which interacts with locks. Cut-off members are coupled with cantilever springs provided with transverse tail pieces. Longitudinal jumpers of separating plates are provided with transverse shelves in their lower part. Shelves have function of locks. They form projections of their inner side for interaction with outer edges of cantilever springs and transverse tail pieces which are positioned behind lower edge of cut-off members.
