Product details
Introduction to D941H-6C flange ventilation butterfly valve
The D941H-6C flange ventilation butterfly valve is designed and manufactured using a new structural form of welding a midline disc plate and a short structural steel plate. It has a compact structure, light weight, easy installation, low flow resistance, large flow capacity, avoids the influence of high temperature expansion, and is easy to operate. No connecting rods, bolts, etc. inside the body, reliable operation, and long service life. It can be installed in multiple workstations without being affected by the flow direction of the medium.
