The Don-Nan gas valve helps maintain proper valve orientation by allowing a small amount of fluid to reenter the pump and aide the standing valve ball in reseating itself on the downstroke. By maintaining proper valve orientation throughout the pumping cycle, the pump is less likely to incur damage due to working with sufficiently full fluid levels.
