Germany JThielmann valve JThielmann model JThielmann price

JThielmann 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 used in conjunction 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; they are generally only used where load changes
