FIELD: machine building.
SUBSTANCE: combined surge and control valve, made with possibility of its use in fluid system, comprises chamber enclosing gate (6, 10, 16, 15), seat (13) and adjusting devices (20-28) for adjusting separating gap distance between gate (6, 10, 16, 15) and seat (13), tracking devices for fluid medium flow rate monitoring flowing through said gap. Adjustment devices comprise movement conversion devices (20-27), activated by actuator device (28), for control of valve gate (6, 10, 16, 15) travel and so preferred change of valve throughput capacity for this change of actuator drive position, wherein actuator drive device (28) includes calibration devices (1, 2, 29, 30, 31) made with possibility of restricting maximum spacing between gate and seat, which can be created by actuator device (28) so that actuator drive device (28) is calibrated in increments, which correspond to rising changes in valve throughput capacity.
EFFECT: equalizing and control.
