Adjustable Chokes

The adjustable-orifice chokes allow varying the equivalent diameter of the orifice in 1/64” increments.

Positive Chokes

Positive chokes allows regulating the flow by using calibrated orifices (choke beans).

These calibrated orifices are supplied in 1/64” increments. The maximum orifice size is 1” for chokes 2-1/16” nominal, and 2” for chokes 3-1/8” nominal.

They are made of cemented iron with ceramic or tungsten-carbide inserts to maintain their calibration during extended periods of use. They are easily replaced with a WEB replacement wrench for calibrated orifices. Orifices up to 5” can be made upon request.
