German von Rohr Armaturen AG valves von Rohr Armaturen AG models von Rohr Armaturen AG prices
von Rohr Armaturen AG valves are valves that control fluid flow by changing the throttling cross-section or throttling length. Connecting a throttle valve and a check valve in parallel forms a one-way throttle valve. Throttle valves and one-way throttle valves are simple flow control valves. In hydraulic systems with fixed-displacement pumps, throttle valves combined with relief valves can form three types of throttle speed control systems: inlet throttle speed control, return line throttle speed control, and bypass throttle speed control. Throttle valves do not have negative flow feedback functionality and cannot compensate for speed instability caused by load changes.
German von Rohr Armaturen AG encoder, von Rohr Armaturen AG model, von Rohr Armaturen AG price
von Rohr Armaturen AG encoders use a photoelectric pulse generator synchronized with the spindle, transmitting synchronization via gears on an intermediate shaft in a 1:1 ratio. There is no direct mechanical connection between the rotation of the CNC lathe spindle and the feed motion. To machine threads, the number of pulses given to the feed servo motor must correspond to the spindle speed; the spindle pulse generator serves to link spindle rotation with feed motion. Threads are continuous ridges and grooves with identical cross-sectional profiles formed along a helix on cylindrical or conical surfaces.
