DN150 butterfly valves for fire trench

 Butterfly trench is using advanced foreign technology and design Shunhang several improvements. It has installed fast, simple and reliable, light weight, flexible operation, easy maintenance, wait advantages. Good seal, but also with the pipe connection desirability of quickness. It can be widely used in water supply and drainage, fire fighting, petroleum, chemical, pharmaceutical, steel and other pipeline as truncated or adjust purposes. Also known as trench trench butterfly handle handle valve, with the installation fast, simple and reliable, light weight, flexible operation, easy maintenance, wait advantages. Both good sealing butterfly handle grooves, but also with the pipe connection desirability of quickness, is the use of advanced foreign technology and design Shunhang several improvements. Trench handle butterfly handle mounted on the valve body flow cards with each other, to control the flow of the fluid. Body ductile iron casting, valve pressure: 2.7MPa. Widely used in water supply and drainage, fire fighting, petroleum, chemical, pharmaceutical, steel and other pipeline as truncated or adjust purposes. Butterfly handle groove is using advanced foreign technology and design Shunhang several improvements. Butterfly handle trench overall unique design, proportion, practical, and is now the preferred valve industry, valve ends with the clamp attached to the fluid conduit, connection or clip connection compared with a conventional flange, saving manufacturing materials, energy saving and emission reduction strategies to follow policies. Easy installation, fast, secure and reliable, and so on. Butterfly has a mounting groove handle fast, easy, safe, reliable, free installation space is limited, piping and valves to facilitate maintenance, there is noise and vibration within a certain range of angles have to overcome the pipeline connecting the different axes and produce poor imitation, solve the resulting temperature difference expansion and contraction. The handle grooves butterfly reliable sealing performance, from the media injection limit (bi-directional sealing, flow area, flow resistance coefficient, flow capacity. Disc with the overall package of plastic aging anti-radiation, durable and so on. Trenches It features a butterfly valve, butterfly valve groove compact, small size, light weight, flexible operation, easy maintenance; 2, reliable sealing performance, from the media injection limit (bidirectional seal); 3, flow area, flow resistance coefficient, flow capacity; 4, the disc plate with the overall package of plastic anti-aging anti-radiation, durable 5, carbon steel as the main material, the use of seamless pipes welded valve, the valve plate is a ductile iron. , reliable quality, beautiful appearance.
