VACCO Industries maintains a product line of stainless and titanium check valves to meet industry’s demand for high reliability and tight leakage. The 3/8” check valve developed for the Mars Ascent program is a titanium welded unit capable of very low external leakage and wide range of temperature extremes (-170° to 45° C). The valve contains an angled-machined seating surface, different from the poppet sealing surface allowing an increase in seat stress. The increase in seat stress improves sealing capability of the valve. This type of design has been in used in other VACCO valves for many years.
