George Fischer Pneumatic Actuator 1" valve used for liquids and gasses #199-223-135, good used condition.  As I have no way to test this item under pressure, I will guarantee it for 30 days, or your money back.  I purchased these as working items surplus, so have no problem with a refund if it does not work. It has a manual shutoff lever next to the ball valve. Everything looks clean and sharp. No dents , cracks, or damage. They are made of industrial plastic material. You can lookup the Model number for more information.  ***** Please look at all photo and ask any questions.  ******  My starting bid is $75.00. for all three! ****  I ship USPS Ground Advantage at about $9.02 to 26.60, depending on the distance, Insurance is extra, over $100.00, if needed. I will ship as soon as the deposit clears from eBay, except Sundays. You have a 4 day inspection period and if this book is not as stated or as the photos show, please return for a full refund. Thank you, Ken Anglin
