In-line threaded, small flow control inserts provide asymmetric flow rate control; free flow occurs in one direction while metered flow occurs in the opposite direction. They are available in sizes from 632 to 516 in brass and stainless steel. They can be used in many applications, including gauge or instrument protection, water hammer control, and cylinder speed control.
