The T E C Bulk Loader Coupling Valve is a major improvement on existing Fuel Couplings, from significantly reducing the number of parts to increasing the length of the handle.

This new design allows one coupling to be used on different train sets.

For the operator, there is a major improvement - extended body length. This ensures that the hands are fully away from the train body, ending the problem of trapped fingers when refuelling.

Improved design of internal slug reduces foaming at supply, allowing reduced fuelling time.

Increased handle length gives easier connect / disconnect 

The Bulk Loader Coupling Valve outer body is manufactured from high grade stainless steel. This combined with a brass internal sleeve gives the Bulk 

Loading Valve the ability to withstand the harsh treatment encountered in its natural environment. The internal operating spring is locked into its location point to ensure the correct operation of the piston on each connect / disconnect. The main seals are manufactured from Viton® to ensure a perfect, hard wearing, seal.

Extensive testing has seen a major reduction in coupling maintenance and significant reduction in leaks.
