Functional principle:
One-directional flow control valves restrict the flow in one direction, while the flow in the other direction is unrestricted. Throttle valves, on the other hand, restrict the flow in both directions according to the setting of the throttle screw. Standard form are the throttle check valves "exhaust regulating". If these are screwed into a cylinder, for example, they enable smooth running without slip-stick effect. Throttle check valves are used in the special form "supply air regulating" for cylinders with a small volume (small diameter/small stroke).
