摘要：
The JSC 'Blagoveshchenskij armaturnyj zavod' issues the steel pipeline fittings including the cast wedge slide-valves (type 3KL) made of the steels 20L, 12Kh18N19TL and 20KhN3L. The slide-valve gate is fabricated as a rigid wedge, the gasket gate surfaces have high wear-proof, corrosion resistivity and hardness. The dimensions are chosen in the optimal ratio what ensures lasting quality and reliability of operation.
