BUTTERFLY VALVES<\/strong><\/h4>\n

The butterfly valve is a rotary motion valve that is used as a throttling valve to control flow through a system.<\/p>\n

Butterfly valves offer several advantages including quarter-turn, openness for less plugging, and good control capabilities.<\/p>\n

Function<\/strong><\/p>\n

Can be used for on\/off service or throttling. When a valve throttles or modulates the flow it is controlling the speed and capacity of media through the valve.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_tta_tabs][vc_tta_section title=”Wafer Type” tab_id=”1691860095578-03ebdf36-5814″][vc_single_image image=”3258″ img_size=”400×200″ alignment=”center” css=”.vc_custom_1691860944195{background-color: #ffffff !important;}”][vc_column_text css=””]<\/p>\n

Wafer Body Style<\/strong> is installed between two flanges using bolts or nuts and studs.<\/p>\n

It does not have protruding legs. The shape is light-weight and has a lower initial and installation cost.<\/p>\n

However, some wafer body styles will not form a proper seal so care should be taken to avoid placing it<\/p>\n

between slip-on or screwed flange types. Wafer style valves are easier to replace and install.[\/vc_column_text][\/vc_tta_section][vc_tta_section title=”Lug Type” tab_id=”1691860097586-5f90f090-4651″][vc_single_image image=”3242″ img_size=”436×300″ alignment=”center” css=”.vc_custom_1691861319657{background-color: #ffffff !important;}”][vc_column_text css=””]<\/p>\n

 <\/p>\n

The double eccentric design facilitates the rapid disengagement of the disc from the seat when opened, thereby decreasing excessive compression and friction between the two components. This configuration effectively reduces operating torque and wear, thereby prolonging the valve’s lifespan. The valve functions by rotating the shaft, which in turn moves the disc to either open or close, thereby regulating the flow of the fluid medium.<\/p>\n

Ideal for applications that require precise shut-off, exceptional durability, and minimal maintenance. It can be utilized in both low and high-temperature environments, contingent upon the material used for the sealing seat.<\/p>\n

Applications<\/strong><\/p>\n

Water Supply and Distribution:<\/strong> Often used in water supply systems, particularly in underground installations.<\/p>\n

Wastewater Treatment:<\/strong> Effective in controlling the flow of wastewater in treatment plants.<\/p>\n

Chemical Processing and Power Generation:<\/strong> Used in systems that require precise flow control and shut-off.<\/p>\n

Key Function<\/h5>\n

First Offset: The shaft is positioned behind the centerline of the sealing surface to provide a continuous seat and seal.<\/p>\n

Second Offset: The shaft is located slightly off the centerline of the bore, which reduces friction during operation.<\/p>\n

Third Offset: The cone axis is inclined from the pipe centerline, ensuring that the seal only contacts the seat at the final point of closure, minimizing wear and providing a bi-directional bubble-tight seal2.<\/p>\n

This design allows the disc to quickly detach from the seat upon opening, reducing unnecessary compression and friction between the disc and the seat. The metal-to-metal sealing mechanism provides excellent durability and resistance to high temperatures and pressures<\/p>\n

Ideal for applications where zero leakage, high durability, and low maintenance are crucial. They are suitable for both low and high-temperature applications, depending on the material of the sealing seat.<\/p>\n

Key Features:<\/h5>\n
    \n
  1. Double Eccentric Design<\/strong>:\n
      \n
    • The valve has two offsets (eccentricities) in its design:\n
        \n
      • The first offset is the shaft being positioned behind the valve disc’s centerline.<\/li>\n
      • The second offset is the shaft being slightly offset from the sealing surface.<\/li>\n<\/ul>\n<\/li>\n
      • This design reduces friction and wear during operation, ensuring a longer lifespan and smoother performance.<\/li>\n<\/ul>\n<\/li>\n
      • Emergency Use<\/strong>:\n
          \n
        • These valves are often used in systems where quick shut-off or isolation is required in emergencies, such as in fire protection systems, oil and gas pipelines, or water treatment plants.<\/li>\n<\/ul>\n<\/li>\n
        • Bidirectional Sealing<\/strong>:\n
            \n
          • The double eccentric design allows for effective sealing in both flow directions, making it suitable for applications where flow direction may change.<\/li>\n<\/ul>\n<\/li>\n
          • High-Performance Materials<\/strong>:\n
              \n
            • Constructed from robust materials like stainless steel, carbon steel, or other alloys, these valves can withstand high pressures, temperatures, and corrosive environments.<\/li>\n<\/ul>\n<\/li>\n
            • Low Torque Operation<\/strong>:\n
                \n
              • The double eccentric design reduces the torque required to operate the valve, making it easier to open and close, even in high-pressure systems.<\/li>\n<\/ul>\n<\/li>\n
              • Tight Shut-Off<\/strong>:\n
                  \n
                • The valve provides a bubble-tight seal, ensuring zero leakage, which is critical in emergency situations.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n
                  Applications:<\/h5>\n
                    \n
                  • Oil and Gas Industry<\/strong>: For pipeline isolation and emergency shut-off.<\/li>\n
                  • Water Treatment Plants<\/strong>: To control and isolate water flow.<\/li>\n
                  • Fire Protection Systems<\/strong>: For quick shut-off in case of fire emergencies.<\/li>\n
                  • Power Plants<\/strong>: In cooling water systems and other critical processes.<\/li>\n
                  • Chemical and Petrochemical Industries<\/strong>: For handling corrosive and high-pressure fluids.<\/li>\n<\/ul>\n
