Our carbon steel ball valves come pre-tested so you can get them up and running immediately. You will also receive a two page test report detailing all opening/closing times after your order has been completed. Festo DFPD Pneumatic Actuators are used in a wide variety of applications, from simple on-off control valves that activate when pressure is applied or released, through complex systems involving multiple actuators and sensors working together in close proximity.
