In a valve closed position seal means in a flat end of the sleeve engage a flat base of a recess in the member 20. The member 20 may be provided with a rotary scraper 41 and heaters located in channels 40 and in this construction the valve is suitable for transferring sodium-cooled nuclear fuel between various localities.
