Cast Steel Centric Butterfly Valves


There are several types of end connections that allow for easy installation of these valves, but the most common are lug and wafer style, both fitting between flanges.
Lug style butterfly valves are similar to 3-piece ball valves -they allow adjacent piping to be removed independently. This is achieved by using two different set of bolts, with each attaching the pipe flanges at either end of the valve body. With this connection to the valve, the ends of the pipe sections can be removed and replaced independently. Installation is also fool-proof as the number of lugs make centering the valves easy.

Butterfly valve is a rotary valve in which a disk-shaped seating element is rotated 90° to open or close the flow passage. They are used in throttling service, particularly where large-size valves with automatic actuators are required. Butterfly valves cannot be used where a nonobstructed, full opening is needed. They offer a size and weight advantage over plug and ball valves.


  • Butterfly valves have several advantages including quarter-turn, openness for less plugging, and good control capabilities. Butterfly valves are rotary motion valves used as throttling valves to control flow through.
  • Small Pressure difference, expecially suitable for big size. To transport large flow of liquid, gas.
  • Butterfly valves are the simple construction not taking up too much space, lightweight.
  • Butterfly valves generally replaced ball valves in many industries particularly petroleum due to lower cost and ease of installation. Disadvantages is difficulty cleaning internal parts. They may be used in a wide variety of chemical services, are available with small dimensions allowing for use in areas where space is limited, and allow a high coefficient of flow.


  • Size: 1.5" ~ 24" (DN40 - DN600)
  • Pressure Rating For ASME: 150# ~ 300# Suit For ASME / MSS / API Flange
  • Body Connection: Wafer Type, Lug Type, Flange Type
  • (Other flange connection please contact Taiwan Valves Centre Co., Ltd.)

  • Butterfly valves can be used for a broad range of applications within water supply, wastewater treatment, fire protection, and gas supply, in the chemical and oil industries, in fuel handling systems, power generation etc.
  • Butterfly valves suitable for coastal and offshore areas as well as in buildings with high condensation problems and contamination.
  • Otherwise,Butterfly Valves may be used in a wide variety of chemical services, for use in water, cooling water, air and powder pipe.
  • Applications from air conditioning, electronic plants, solar plants, paper mills, etc.

WCB - This steel has a good welding characteristic, suitable for use in the environment needs seat overlay welding. Butterfly Valves may be used in a wide variety of chemical services, for use in water, cooling water, air and powder pipe.Butterfly valve mainly used for start and stop the flow. Butterfly valve’s benefit is that can be opened very fast. Because butterfly valve consists of circular discs built with a stem through the middle or attached offset. When opened, the disc pivots 90 degrees in the valve bore, aligning with the flow, creating a nearly unrestricted flow path. A 90° rotation of the disc/handle results in a complete closure or opening of the butterfly valve. Butterfly valves operate similarly to ball valves in their 90-degree rotation and allow for quick shutoff. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate and fast, and also has good flow regulating function and closed sealing characteristics. Butterfly valve has a small flow resistance when fully opened. When the opening is between about 15° and 70°, sensitive flow control is possible. Especially for large pipe diameters, butterfly valves usually provide the most cost-effective solution, so butterfly valves are very common in big pipe applications.
