Koso Kent Introl – Surface Choke Valve Series 73

All Series 73 Choke Valves use a low-pressure recovery, High Friction trim design. This protects the vital pressure-containing boundaries of the valve against damage from erosion and cavitation. It does so by dissipating and controlling velocity, pressure, energy and turbulence within the confines of the trim. Dependent on the needs of your project, the Series 73 range can work with single or multi-stage trims.

Multi-stage trims can protect the valves further against the effects of cavitation and high velocity erosion. Holes in the trims are aligned in such a way as to force individual jets to change direction repeatedly as they pass through the chambers between sleeves. This results in a controlled, steady reduction in pressure and velocity control preventing the onset of cavitation.
