ower management firm Eaton – now a part of Danfoss Power Solutions (Sealing Technology, September 2021, page 2) – lately expanded its product portfolio with the addition of the sturdy WALRINGplus gentle seal chopping ring system, optimised for thin-wall tubing.
Featuring a two-edge cutting ring, with additional delicate sealing for both possible leak paths, this tube becoming system permits straightforward, secure and repeatable assembly and reliable, leak-free operations.
It is designed to fulfill demanding necessities, involving hydraulic tube fitting in functions together with use in agriculture, development, commercial vehicles, discrete manufacturing, rail transportation and different industries.
weksler ea14 is suitable for use with thin-walled tubes and, due to this fact, helps environment friendly weight and fuel reduction of cellular equipment and moving components of stationary machinery.
Correct assembly is essential to tube fitting efficiency and WALRINGplus is designed to prevent excessive or insufficient tightening. A clear block-stop perform provides a tangible torque increase when the end of an assembly is reached, so no torque or distance measurement is required.
In addition, a significantly lower drive is needed to drag the cutting ring over the tube – making meeting simpler, sooner and safer, while lowering the chance of injury to the gentle seal. The O-ring groove place additionally enables frequent reassembly, with out affecting performance.
To eliminate the danger of leaks that may create costly injury and downtime, WALRINGplus additionally addresses their common root causes.
Soft sealing prevents leakages if: tubes or studs are barely scratched, the fluid temperature fluctuates or the retention pressure is decreased. Problems attributable to low assembly torque additionally can be recognized earlier than the cutting ring is pulled from the tube – reducing the chance of a catastrophic failure in application.
The bespoke M-R7 machine additional reduces meeting time and the trouble required for WALRINGplus as properly as the chance of leaks. By automating the method of cutting-ring assembly and tube-forming, this machine helps ensure optimum system efficiency while additionally lowering the required torque and rotrotation.
Specifications of WALRINGplus: • metal chopping ring with Viton O-rings; • for tube sizes 6–42 mm; • complies with ISO 8434-1; • high burst-pressure exceeding four:1 safety issue; • working stress as a lot as 500 bar (L-series) and 800 bar (S-series); and • helps dry assembly with steel parts.
