Apr 29, 2002 Blocking fittings mount on air cylinder port and use independent pilot air signal to block movement of piston rod at selected positions. Slow Start fittings control speed at which cylinders recover position. Flow Control Regulators are unidirectional and adjust speed of cylinder rod by controlling inlet or outlet flow. Inline Flow Controls mount anywhere and can be ganged together. Right Angle Flow Controls are for direct mounting on cylinders.
