Designed to ensure drilling mud circulation during lowering of the casing column, flushing of bottom hole and casing annulus when completing non-cemented boreholes in multi-layer formations in the open hole of at least 4-3/4 in (121 mm) diameter. When activated by the ball, the sleeve ensures testing of casing pressure and preparation for activation of frac initiator sleeve (strengthened) FIS- 4" (102)/S.
