3PC FLOATING DOUBLE BLOCK AND BLEED BALL VALVE

Product Description

3PC Floating Double Block and Bleed Ball Valve has two balls and one or two needle valves,the two ball valves can opend and closed the medium and two needle valves can discharge pressure of the valves, DBB double ball valve has two series of full diameter and reduced diameter. The inside diameter of the full diameter ball valve is in line with the inner diameter of the pipeline, not only with small fluid resistance, but also convenient for pipeline cleaning. The fluid resistance of the shrink ball valve is much lower than that of the same caliber cut-off valve. The weight of the ball valve is about 30% lighter than that of the same caliber ball valve, which effectively reduces the cost and price of production, thus it has been widely used.
