FIELD: pneumatics; shutoff devices using working gas for pneumatic control. SUBSTANCE: valve has body with seat, valve with seal, passage part, piston pneumatic drive with piston slot seal. Valve is installed directly in passage part and is controlled by working medium. Single-acting piston pneumatic drive is used. Diameter of piston of pneumatic drive is smaller than that of valve. Flange made on valve protects seal from erosion. EFFECT: enhanced reliability of valve operating under preset pressure differential, reduced consumption of control gas. 1 dwg
