The Hydraulic Choke is a hydraulically operated variable choke providing any opening from a maximum of 1.93 square inches (1 9/16” equivalent bean diameter) to full shut off. The working pressure rating of the choke is 10,000 PSI. Two Tungsten Carbide discs, each with a semi-circular opening, form the choke. Various openings are obtained by rotating the upstream disc against the stationary downstream disc.
