FIELD: manufacture of valves; control of compressed gas flow rate. SUBSTANCE: valve has body, seat installed for adjusting its position relative to body axis, sealing members and shutoff-and-control member with conical locking surface and a step of smaller diameter located with radial clearance in seat intake channel. Made on the end of step is surface inclined to its axis; and circular grooves, triangle in cross-section are made between the inclined surface and conical locking surface. EFFECT: higher efficiency. 2 dwg
