Butterfly valve, also known as flap valve, is a simple structure of the control valve can be used for low-pressure pipeline media control switch butterfly valve means the closure (valve flap or disc) as a disc, rotating around the valve shaft to open and close A valve that can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, slurries, oils, liquid metals, and radioactive media. Mainly in the pipeline cut off and throttling effect. Butterfly valve opening and closing pieces is a disc-shaped disc, the valve body around its own axis of rotation, so as to achieve the purpose of opening and closing or regulation.
Butterfly valve mainly by the valve body, stem, butterfly and seal composition. Body is cylindrical, short axial length, built-in butterfly.
Pentair butterfly valve has the characteristics of simple structure, small volume, light weight, material consumption, small installation size, rapid switching, 90 ° reciprocating rotation, small driving torque and the like for cutting off, connecting and regulating the medium in the pipeline , With good fluid control features and close the sealing performance. Pentair butterfly valve can transport mud, liquid storage in the mouth of pipe at least. Under low pressure, a good seal can be achieved. Good regulation. Pentair butterfly streamlined design, the fluid resistance loss is small, can be described as an energy-saving products.
Over the last ten years, castellated beams have been an excellent engineering solution, ushering in significant development in the construction of lighter-weight floor slabs with much higher dimensions and load-bearing capacities than traditional beams. At the same, it proved possible to improve the appearance of the products, by integrating system and lighting components more effectively. This technical-engineering solution has also led to new developments in the eld of architecture/urban furnishings. Laser cutting is the best technique to obtain extremely clean and precise finishes, and produce castellated beams without any restrictions in terms of shape and dimensions: XUANLIN CNC `s laser operational and design skills find expression in the creation of complete structures, designed and manufactured in partnership with major international players, while guaranteed shorter lead times and unique precision at the assembly stage.
If you are looking for a partner for the production of laser beams, as well as for laser cutting metal sheets and tube
laser cutting guarantees you reliability, experience and quality of the final product.
