    These low cost flow controls employ a check valve with a stainless steel or buna-N ball and a precision orifice. Free flow occurs in one direction and metered flow occurs through the precision orifice in the opposite direction. Available with 10-32 threads, the fixed flow controls are available as a set screw or as a male/female fitting.
