SUCCESS STORY - Ball Type Expander Plug

Industry: Hydraulics 

Application: Metal-to-metal Seal in Manifolds

Summary:

The Application Process, and Challenges:  

hydraulic manifold is an important component that regulates fluid flow between pumps and actuators &other components in a hydraulic system. It is like a switchboard in an electrical circuit because it lets the operator control how much fluid flows between which components of a hydraulic machinery. 

It is a block of metal with flow paths drilled through it, connecting various ports and consist of one or more relative large pipes called a "barrel" or "main", with numerous junctions connecting smaller pipes and ports. The main challenged here was to permanently close off (seal) ends of cross-drilled holes that create flow patterns for actuation. In some cases, they had few options due to the pressures being 3,000 to 5,000-plus psi. Threaded plugs, welding and ball bearings were commonly used, sometimes in combination, to avoid leaks. But these efforts often created more issues than they solved, such as larger manifolds, additional processes, added costs and extra weight.

The manufacturer reached out to Avlock India for a permament & reliable solution. Our Product Experts suggested resolution which could

perform better than the existingby providing them a permanent, easy-to-machine-and-install alternative to costly, often-cross-threaded, SAE-style threaded plugs.

 

About the product:

SFC Koenig Ball-Type Expander Plugs

Ball-style plugs are ball bearings inside of machined can or sleeve plug bodies that started out as a high-pressure, leak-proof, permanent seals.

These are well-suited for low and high-volume installation and adaptable to fully automated installation. Leading the field of high-quality metal-to-metal sealing and flow control technology, SFC KOENIG develops & manufactures a wide range of sealing solutions (expander plugs & non-return valve) products which are highly reliable solutions, especially in areas where sealing & flow control are critical. Its Sealing Plugs MB series helped the manifold manufacturer to improve their production time & reliability of their application.

Features of SFC Koenig Ball-type Expander Plugs:

  • Short installation dimension
  • Ideal for installation using processing or automated tools
  • Reliable metal-to-metal sealing
  • Available in steel, stainless steel & aluminium
  • working pressure up to 450 bar

push style sealing plug

 

Results to the customer:

  • Reduction in the processes; like creating taps, load-bearing threads & riming (creation of smooth surface); of holes created to seal the end of the communication path 
  • Removal of Leakage
  • simplified installation
  • reduced size of the applications
  • decreased weight (mass)
  • Less material cost 
  • no cross-threading & rework
