ower management firm Eaton – now part of Danfoss Power Solutions (Sealing Technology, September 2021, web page 2) – lately expanded its product portfolio with the addition of the strong WALRINGplus delicate seal slicing ring system, optimised for thin-wall tubing.
Featuring a two-edge slicing ring, with extra delicate sealing for both potential leak paths, this tube becoming system allows easy, secure and repeatable meeting and dependable, leak-free operations.
It is designed to fulfill demanding requirements, involving hydraulic tube becoming in purposes including use in agriculture, building, industrial vehicles, discrete manufacturing, rail transportation and other industries.
It is appropriate to be used with thin-walled tubes and, subsequently, helps efficient weight and fuel reduction of mobile machinery and transferring parts of stationary machinery.
Correct meeting is crucial to tube fitting efficiency and WALRINGplus is designed to prevent extreme or insufficient tightening. A clear block-stop function supplies a tangible torque enhance when the top of an assembly is reached, so no torque or distance measurement is required.
In weksler ea14 , a significantly lower force is required to drag the slicing ring over the tube – making assembly simpler, sooner and safer, whilst reducing the risk of harm to the gentle seal. The O-ring groove position additionally permits frequent reassembly, without affecting efficiency.
To get rid of the chance of leaks that can create costly harm and downtime, WALRINGplus additionally addresses their widespread root causes.
Soft sealing prevents leakages if: tubes or studs are barely scratched, the fluid temperature fluctuates or the retention drive is lowered. Problems caused by low meeting torque additionally may be recognized before the chopping ring is pulled from the tube – lowering the danger of a catastrophic failure in utility.
The bespoke M-R7 machine further reduces assembly time and the hassle required for WALRINGplus in addition to the danger of leaks. By automating the process of cutting-ring meeting and tube-forming, this machine helps ensure optimum system performance whilst additionally decreasing the required torque and rotrotation.
Specifications of WALRINGplus: • steel cutting ring with Viton O-rings; • for tube sizes 6–42 mm; • complies with ISO 8434-1; • high burst-pressure exceeding 4:1 safety factor; • working stress as much as 500 bar (L-series) and 800 bar (S-series); and • helps dry meeting with steel elements.
