Parker 9F800S Throttle check valve stål muffe/muffe

Throttle-check valve for precise regulation of the oil flow. A two-step needle enables a very precise throttling at the startup of the oil pressure, which happens during the first 3 turns of the adjustment knob. The next 3 turns provide full throughput of the oil in the valve. The valves are delivered with a Colorflow scale, allowing easy return to previous settings and quick regulation to new quantities. The valve can be locked with a screw to prevent unintended changes.
