ValvesDepending on the application area, Parker QCDE coupling systems are available with straight-through, single or double shut-off, and in clean break design. To ensure fault free operation all valve seals are the same as the main seal choice.
Dirt ProtectionFor outdoor applications, we have developed coupling systems that have seals integrated both into the unlocking sleeve and into the plug – the complete coupling (incl. locking system) is there-fore sealed when coupled and it is effectively protected from dirt and spray water.
• High resistance to vibrations and dirt (e.g. NSR-Series).• Certified safety – vibration and shock test in accordance with DIN EN 61373/IEC 61373.• Low pressure drop for maximum energy efficiency.• Compact design for installation in applications where little space is available.• Various sizes from nominal diameter 3 mm up to 50 mm.• Broad selection of sealing materials for optimal co-ordination with temperature (-55°C up to +250°C)
and flow medium.• High resistance to rotation.• No leakage when disconnected due to the specially developed valve design – even after a long time and
pressurisation (all flat-sealing variants).• Push-pull function – pull-off function for system safety and time saving, particularly with systems in
motion (e.g. FF-Series).
We meet the highest requirements!Quick connect coupling systems from Parker – a safe solution in the area of rail vehicles
Vibrations, dirt and extreme mechanical and climatic stress are the principal challenges for our quick connect coupling systems in the area of electric and diesel-powered rail vehicles. The functional safety of the systems plays a major role here with the many electronic, pneumatic and hydraulic controls, in addition to the requirements with respect to reliability (failure safety) and availability. Particularly in the area rail, there are specific
directives and safety standards for processes, with which our systems must comply (for example the vibration and shock test in accordance with DIN EN 61373/IEC 61373).
With over 60 years of experience in the development and sale of high-quality quick connect coupling systems, the Quick Coupling Division Europe of Parker Hannifin – the world’s leading manufacturer in motion and control technologies – now
offers one of the most extensive product ranges of innovative connection solutions. Whether for complete or sub-systems, we always have a tried and tested solution.
From standard product to bespoke systems, our team is available to provide you with competent advice at any time. We are happy to provide detailed advice – please ask us.
MaterialsFor coupling systems in the area of rail vehicles, the materials brass, stainless steel and aluminium in particular have proven themselves. Brass is generally used with a nickel plated finish – depending on the series, we offer stainless steel in qualities AISI 303, AISI 316 L and AISI 2205. Other materials are also possible of course, depending on application. Our team is happy to advise you here.
EPDM or NBR seals as standard
Other materials available
SealsA coupling can only be as good as its sealing components. This is why we rely on EPDM and NBR as standard for our sealing materials – particularly NBR for extremely low temperatures. For challenging requirements, our experts will, of course, offer completely individual advice and develop an optimum solution.

Plumbing and Water Treatment
Quick connect couplings are also used in the area of on-board toilet systems and water treat-ment in mobile installations. A special system has been developed in the area of vacuum toilets.
• Development of a complete system: series 26 is jointly responsible for filling the water tank; series 21 brings applies pressure to the toilet in the flushing process so that the water can be flushed out accordingly – until the purge valve is opened.• Use of non-corroding coupling systems.
Toilet Systems, Water Treatment and Sprinkler Systems
Hydraulic couplings are essential for coupling and uncoupling attachments on rail and track vehicles. From railway construction machines to winter and summer equipment (e.g. snow plough, snow blower, mulcher etc.), almost all equipment can therefore be changed quickly and easily.
• Flat-face systems guarantee protection of the environment and of the hydraulic circuit.• Quick and easy assembly.• No freezing of the unlocking sleeve in winter.• Pressure eliminator allows coupling even with residual or dynamic pressure. The special valve structure automatically relieves the pressure in the coupling element when coupling.• Tilt control of rail vehicles.
Hydraulic Applications
For filling and replacing battery fluid, Parker QCDE has developed a special coupling system for the area of rail vehicles, which is used both in initial fitting and in main-tenance.
• Extremely light due to material selection of aluminium.• Special seals that withstand distilled water long-term.• Quick coupling systems with dry-break locking system allows clean handling and protec- tion of the surroundings.
Battery Systems
Other Applications
To this day, pneumatics remains an important element in rail vehicles. Coupling systems from Parker QCDE are used in many applications for connecting compressed air compo-nents:
• In purely pneumatic door drives.• For folding steps, sliding steps and ramps with pneumatic drives.• In sanding systems.• In pneumatic pantograph systems.
