The UKF pallet van was a bogie freight wagon that would be a relatively common sight on UK rails during the 1970s and 1980s. The 'Palvans' had an 82 tonne capacity and were designed to transport palletised products on the rails, in the UK this often took the form of fertiliser from the UKF company. UKF would be known as Shellstar before adopting the name of the Dutch company Unie van Kunstmest Fabrieken.

Initially versions of the Palvan were curtain sided with newer versions being constructed with sliding side doors. This enhancement would prove to be a success, and earlier wagons would be retrofitted with their curtains removed and doors fitted. All of these received the TOPS code PWA.
