Brief Introduction Of High Performance Butterfly Valve | Feidavalve.com

  High performance butterfly valves are usually made from metal like stainless steel or cast iron because they offer the most strength and durability against high pressure. They can range from less than a foot to more than a yard in diameter depending on the application. Different kinds of butterfly valves are used in different situations; triple offset butterfly valves, for example, are used for pipe lines with moderate to high pressures that require more control and tighter seals whereas  FEID AVALVE high performance butterfly valves  are sanitary and are therefore used in water pipes. High performance butterfly valves are constructed using solid pieces of high quality metal in order to exceed the standards of regular valves. These hydraulic and pneumatic valves can be used in many situations that transport water, chemicals, slurries and gases among other substances. High performance butterfly valves are usually double offset valves that are designed to be eccentric in two places. Th

A  Butterfly valve  is a quarter-turn rotational motion valve, that is used to stop, regulate, and start flow. A butterfly valve has a disc which is mounted on a rotating shaft. When the butterfly valve is fully closed, the disk completely blocks the line. When the butterfly valve is fully opened, the disc is at a right angle to the flow of gas or liquid. The butterfly valve consists of only four main components: body, disk, stem and seat. Butterfly valve body: Butterfly valves generally have bodies that fit between two pipe flanges, the most common being lug and wafer body design. Butterfly valve disk: The disk is how the valve stops flow – it is equivalent to a plug in a plug valve, a gate in a gate valve or a ball in a ball valve. There are variations in disk design and orientation in order to improve flow, sealing and/or operating torque. Butterfly valve Stem: The stem of the butterfly valve may be a one-piece shaft or a two-piece (split-stem) design. The stem in most resilient sea
