Profile: Gardner Valves And Process Controls Inc. is a manufacturer of ball valves. We offer high temperature, metal seated, high pressure, abrasive & corrosive, and cutaway ball valves. Our products are used in chemical, mining, petrochemical, automotive and power industries. Metal seated ball valves are often used as the solution to seat damage problems. We ensure that the interface geometry between the ball and seat results in low seat loading, which allows for increased frequency of operation without producing excessive heat.
