Parker Hannifin Replaces Steel with VICTREX® PEEK(TM) Polymer in Its New Hydraulic Coupling System
WEST CONSHOHOCKEN, PA, USA - (January 14, 2010) - When Parker Hannifin, Mainz-Kastel, Germany was looking to replace the steel components of its RSD quick couplings with one single injection molded component that reduced the number of components to be assembled and control the overall production costs, they selected VICTREX® PEEK(TM) polymer.
The RSD series couplings are used to rapidly and easily connect and disconnect the hydraulic lines between a tractor and its various items of equipment (trailer, plough, etc.) without using any tools.
The technology of the RSD coupling allows for a completely safe connection of a male connector, whether pressurized or not, under adverse conditions, such as under a maximum pressure of 250 bar (3626 psi), and withstands a return flow rate that may reach 190 l/min (50.2 gallons/min) and even beyond for a few seconds at a temperature close to 120°C (248°F). "Apart from the high performance demanded of the coupling, it was essential for us to control our production costs by reducing the number of metal components," said David Aragones, Project Manager at Parker Hannifin. "Consequently, we sought a multipurpose material that was both highly flexible and capable of withstanding high loads over a wide range of temperatures in order to allow us to incorporate as many functions as possible in the clip."
The VICTREX PEEK polymer valve minimizes the number of components in motion during connection and disconnection which improves reliability. The shape of the clip combined with the elasticity and the fatigue resistance of material ensures a reliable and durable connection of the pressurized male connector. "The use of this high performance plastic has allowed us to offer an entirely innovative, patented design," stated Aragones. "These connectors are particularly valued for their pressure-resistant characteristics and their compactness."
"VICTREX PEEK polymer retains its mechanical properties even in aggressive environments at high temperatures. Apart from its outstanding thermal performance, it also presents a unique combination of properties," said Didier Padey, Market Development Manager at Victrex Europe. "In this case, it is the mechanical resistance and ductility, even under the most adverse conditions, that led to specification of VICTREX PEEK polymer for the valve clip of the RSD hydraulic couplings from Parker."
Thanks to the cooperation between Victrex, the designer and the subcontractor in charge of production, VP PLAST, Parker was able to achieve increased design freedom and simplified implementation by injection molding, while improving the functions of its RSD coupling.
