Abstract
A manual check valve for use when priming a fluid supply for a spray gun includes an orifice that opens from the fluid supply into a storage chamber, the storage chamber captures any fluid that is expelled from the fluid supply during priming, and the storage chamber is sealed with a closure. Sealing the storage chamber traps any expelled fluid in the storage chamber and prevents any of the expelled fluid from leaking onto another surface, which keeps the priming operation clean.
