FIELD: power engineering.
SUBSTANCE: invention can be used for organizing flows of working gas in passage part of positive displacement machines, mainly, compressors. Proposed valve has seat, lift limiter and shutoff member with slots divided by lands placed between seat and lift limiter. Slots in seat and shutoff member are arranged in rows so that distance between axes of rows is defined by expression b=a(0.75+2δ/a+δ2/a2)1/2 where a is slot defining size; δ is minimum distance between slots of adjacent rows.
EFFECT: increased service life of valve.
