German AVK valves, AVK models, AVK prices

AVK 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 fixed-displacement pump hydraulic systems, throttle valves used 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 lack negative flow feedback and cannot compensate for speed instability caused by load changes; they are generally used only where load changes are small or where speed stability requirements are low.
