A butterfly valve is a quarter-turn rotary motion valve used to stop, regulate and start flow. Butterfly valves are easy and quick to open. Turning the handle 90\u00b0 allows the valve to fully close or open. Large Butterfly valves are usually equipped with a gearbox where the gear wheel is connected to the body. This simplifies the operation of the valve.<\/p>\n

Typical applications of butterfly valves<\/strong><\/p>\n
A Butterfly valve can be used in many different non-critical applications and performs well in Slurry applications. Some typical applications of Butterfly valves are given below: <\/p>\n
<\/p>\n
Cooling water, air, gases, fire protection, etc. Slurry and similar services vacuum service High pressure and high temperature water and steam services<\/p>\n
<\/p>\n
Advantages of butterfly valves<\/strong><\/p>\n
Compact design requires much less space compared to other valves Lightweight Fast operation requires less time to open or close Available in very large sizes Low pressure drop and high pressure recovery Reasonable price<\/p>\n
<\/p>\n
Disadvantages of butterfly valves<\/strong><\/p>\n
Throttle service is limited by low differential pressure Cavitation and blocked flow are two possible concerns Disc movement is unguided and affected by flow turbulence<\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”full_width_background” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” bg_color=”#f7f7f7″ scene_position=”center” top_padding=”100″ bottom_padding=”100″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_spacing=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text]\n
