OEMic
manufactures both Positive and Adjustable chokes. Adjustable Chokes are
meant for variable flow. It has externally controlled indicator showing
orifice size in the increment of 1/64th inch. The variation in choke size
is achieved by rotating hand wheel to obtain desired flow rate at down stream side. Positive Chokes accommodate fixed
orifice dimensions. All OEMic Adjustable Chokes
can be converted into Positive Chokes by replacing the bonnet assembly with
an appropriate blanking plug assembly and choke bean .
