Tungsten Carbide Valve Choke Bean / Choke Seat / Choke Beans For
Oil & Gas Industry
Choke bean used in the positive chokes for controlling the
flowrate, and are usually mounted on or close to the wellhead
equipment.High pressure gas/oil, with abrasive sand minerals passes
through these chokes at high speed causing rapid wear. Bean chokes
contain a replaceable insert, or bean, made from hardened steel or
similar durable materials.
