I am looking for a vacuum test device for the One Way Valve (aka Check valve or Non-return valve). Does Kirby Morgan make this? Where can I get one?

Kirby Morgan does not make a vacuum controlled test device for our one way valves (555-195). This device was used back in the 1980s (not made by Kirby Morgan) but this tester was phased out long ago. Vacuum controlled one way valve testers are not necessary and are no longer commercially available for our equipment. The current and approved method for testing the one way valve is covered in the Kirby Morgan Owners Operations & Maintenance Manuals.
