FIELD: machine engineering.
SUBSTANCE: shut-off, cut-off valve includes a body with inlet and outlet unions, an atmospheric channel, a locking mechanism and a control unit. In addition, the locking mechanism comprises a spring-loaded locking bolt arranged in the body cavity dividing the cavity into the working, pressure and atmospheric ones, and a lock. The control unit contains automatic and mechanical drives, channels for supplying control medium connecting the body working cavity to said drives and control channels connecting said drives and the body pressure cavity.
EFFECT: increased valve functionality by performing both cut-off valve and shut-off functions, with simultaneous simplification of design due to utilisation of its working medium for the valve control.
