Products Description
D381X-16Q Grooved Type Gear Butterfly Valve
Product Usage
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.
