D381X-16Q Grooved Type Gear Butterfly Valve

The Usage of the Product

In the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. The valve is widely used in the water supply and drainage of the conveying fluid pipeline, and the pipeline engineering such as fire air conditioning, water treatment, municipal administration, shipbuilding, etc., acts as a control fluid. Both ends are connected to the fluid pipeline with clamps. Compared with the previous flange connection or wafer connection, it greatly saves manufacturing materials and follows my country's strategic policies for energy conservation and emission reduction. Installation is convenient, fast, firm and reliable.
