Butterfly butterfly valves
Butterfly butterfly valves are a relatively new type of valves designed to solve a certain range of tasks for regulating and shutting off the flow of the working medium in large-diameter pipelines with low pressure and reduced tightness requirements in the closed state. This type of valves got its name from - behind the disc blocking the section of the shutter, fixed on the rotary axis, perpendicular to the direction of the main flow. The Butterfly valve body is made of cast iron with a special elastomeric painting, the locking element is made in the form of a cast iron or stainless disc, the control is carried out manually (up to a diameter of 250-300 mm) and a mechanical gearbox (for diameters over 300 mm). The advantages of this type of shut-off valves include light weight and relatively low cost compared to gate valves, small dimensions and low flow resistance, visual control of the disk position (for valves with a control lever), ease of flange mounting due to a special sealing clip and short closing time / opening. Disadvantages of butterfly valves are reduced tightness of the valve in the closed state, increased efforts to control the valve with large diameters and hydraulic resistance created by the shut-off disk in the open state. it is enough to turn the lever 90 degrees from the initial position.
