Eclipse Butterfly Valve

The Eclipse Butterfly Valve works to control air or gas flow for your combustion system. Reliable and easy to maintain — helping you reduce direct operating costs and minimize the time required for valve maintenance.

What is a butterfly valve?

A butterfly valve is a quarter-turn rotational motion valve that assists in regulating air or gas flow. The valve consists of four major parts

 

  • Body that fit between two pipe flanges.
  • Butterfly valve disk that works to stop flow.
  • Butterfly valve stem that can come in a one-piece shaft or two-piece (split) design.
  • Butterfly valve seat that uses an interference fit in between the disk edge and seat for shutoff.

 

What can I use a butterfly valve for?

There are many ways you can use a butterfly valve. These valves have a wide range of applications that perform well in both high volume water and slurry applications. Here are some of the more common ways butterfly valves are utilized.

  • High pressure water and steam services
  • High temperature water and steam services
  • Cooling water, air gases and fire protection
  • Slurry or similar services
  • Compressed air or gas applications
  • Vacuum services

The Eclipse

The Eclipse Butterfly Valves are great for regulating and controlling air or gas flow. However, these valves are not designed as tight shut-off valves.

There are several types of Eclipse Butterfly valves and accessories available for manual or automatic control.

  • Pipe sizes ½” – 8”
  • Full port constructions
  • Reduced port constructions
  • High pressure constructions
  • Beveled or non-beveled disks

Accessories

  • Optional crank arm or coupling for integration with a range of position control devices
  • Electric operators and mounting kits can be purchased separately
  • Extended shaft allows for second control arm for concurrent automatic operation in dual valve application or a cam for a high/low fire microshift configuration

There are also several thread connections available for the Eclipse Butterfly Valve

  • ½” – 4” for either Rc or NPT threads
  • 6” and 8” wafer style butterfly valves to fit between flanges on connecting pipes

Butterfly valve vs. gate valves

There are many advantages of utilizing a butterfly valve versus a conventional gate valve.

  1. Butterfly valves are lighter and smaller, so they are simpler to manage and install
  2. Because butterfly valves only need a quarter turn to open and close — they are easier to operate and shut-off openings faster
  3. Shorter shaft allows for easier access
  4. More cost-effective and cheaper to purchase
