Automatic connection featuring easy maintenance for the end user, reduced assembly time of the train for the manufacturer and easy connections and disconnections of the circuits even.
An expert manufacturer of high-quality quick-release couplings for more than 50 years, Stäubli has developed connection solutions specific to the railway industry, offering connection solutions for all types of trains, locomotives and trams.
Our products encompass all applications and types of fluids, compressed air, hydraulics, cooling systems, fill and drain, and electrical power, as well as customised connection solutions, all designed to resist the most demanding mechanical and climatic conditions.
Operating on a global scale, we can participate in the coordination of all major international projects with your subcontractors and integrator sites. Directly in contact with you in all countries, our sales team will bring you the appropriate solution for your applications to meet your exact specifications.
Compressed air connections for trains and trams
Stäubli’s compressed air connection solutions for the railway industry include quick-release couplings for a wide range of applications, such as body-to-bogie and interbody, pneumatic connections for braking circuits, suspension, sandboxes, wheel flange lubrication and main circuits, all designed for optimum performance and long-term durability.
Pressure point and levelling valves for compressed air
Stäubli offers a wide range of quick-release couplings for pressure point and levelling tests on passenger and freight rolling stock, with special connection solutions for consistently accurate measurement and effective control of crucial circuits.
Thermal management and air conditioning for trains
Stäubli quick release couplings offer innovative connection solutions for cooling on-board electronic equipment, engines and transformers, as well as filling and draining. Our ongoing dedication to meeting the changing needs of the railway industry has resulted in couplings for all types of fluids, including glycol water, heat transfer oils and esters.
Hydraulic connections in trains and trams
For the connection of hydraulic brake circuits, hydraulic tilting circuits, brake calipers, pressure accumulators and hydraulic pressure units, Stäubli has developed quick release couplings with very high resistance to mechanical stress and difficult conditions. Featuring clean break non-spill design, our hydraulic connection solutions also offer an environmentally sound alternative.
Non-spill self-aligning couplings CGO and CGD
Non-spill flush faces technology guarantee that no pollution enters the circuits on connection:
- Appropriate sealing solutions allows CGO and CGD range to be compatible with the majority of fluide and to cover a large range of temperatures
- Non-drip to ensure cleanliness and safety of installations and operators.
- On disconnection the circuits close automatically, thanks to the double shut-off of CGO and CGD couplings:
- No contamination of environment from fluid loss
- Especially suitable for electrical and high voltage environment.
CGO and CGD are designed to compensate and allow ‘blind’ coupling.
Features include leak-tight couplings including on connection and disconnection. Sealing takes place before the opening of the valves on insertion of the plug into the socket, which avoids the need to purge the circuits and prevents any contamination of fluid.
Pollution free, non-spill, flat faces mean that there is no introduction of air into the circuits on connection, and no lost of liquid on disconnection making complete circuit bleeding unnecessary. Light and compact couplings made from high performance treated aluminium alloy for light weight. Optimum flow with internal design ensures a low pressure drop for an optimum flow in compact overall dimensions.
Features of Stäubli's quick-release coupling include non spill flat faces with no lost of liquid on disconnection, long guiding of plug into the socket for a constant tightness even under severe conditions of use, and a quick and safe locking with a large number of locking balls for high strength under severe conditions of use (such as vibrations or oscillations).
The high level of performance, the reliability, the robustness and the proven sealing of our quick-release couplings are important benefits providing an accurate measurement and rapid and effective control of these crucial circuits.
