Faster and simpler QD couplings from Eaton

Eaton says that its new offering enables more compact, powerful and fuel-efficient machines in many industries including agriculture, construction and commercial transport. The company’s Multiplate system supports two to six FF Quick Disconnect Couplings simultaneously and says that it makes connectivity both faster and simpler during assembly and maintenance.

The new design is stated to offer manufacturers greater design flexibility and also allow for the creation of smaller, lighter and more energy-efficient machines. Manufacturers can benefit from the system`s optimised weight, says Eaton, as well as the ability to easily move attachments and create connections in the field. Simple assembly, installation and maintenance is further supported by an internal mechanism that lowers the connection force required  by 40 percent compared to previous offerings, with the advantage of the ability to integrate with Eaton’s Flat Face Series Disconnect couplings.

Currently, Eaton says that its FF series supports 60 percent higher working pressures and up to 74 percent higher flow rates compared to ISO 16028 standards, which results in lower energy loss and optimised fuel consumption. The new Multiplate system is claimed to further maximise machine performance whilst enhancing machine reliability and safety by eliminating the risk of crossed lines. The Multiplate system is made with Eaton’s nickel-free Guardian Seal™ coating, which comes as standard on the Quick Disconnect Couplings in the system’s fixed and movable plate. This coating provides up to 1,000 hours of corrosion resistance even in the harshest of environments. The Multiplate system’s fixed plate, moving plate and handle also come in anodised aluminum to ensure longevity.

Cleanliness is another crucial factor in the performance and operational lifetime of hydraulic systems. When using Eaton’s connect-under-pressure plug, FF Quick Disconnect couplings can be connected at up to 350 Bar residual pressure without leaking or taking in air and contaminants. This enables faster maintenance by not requiring the time or specialised tools needed to depressurise the entire system. Eaton’s Multiplate system is said to further reduce the risk of contamination thanks to an integrated sealing band between the plates and a dust cap that automatically closes when couplings are disconnected. Designed to be highly customisable, Eaton’s Multiplate system also offers optional electrical connectors, specialised couplings for water or air and flat face couplings in alternative materials.
