German AIR TEK valves, AIR TEK models, AIR TEK prices

With a constant pressure differential across the AIR TEK valve, the flow rate of a standard valve changes little when the opening varies over a wide range, but changes sharply at a certain opening, indicating poor regulation performance. A control valve adjusts the valve core stroke according to the direction and magnitude of the signal to change the valve's resistance coefficient, thereby achieving flow regulation. Control valves are divided into manual and automatic types, with various subtypes exhibiting different regulation performances. Automatic control valves include self-acting flow control valves and self-acting differential pressure control valves. AI
