Model 74TS - "Cage release" control valve

The cage release control valve is a special design control valve that is ideally suited to hydrocracking or hydrotreating applications.

It has a multi hole cage disk design with a variety of hole placements in order to achieve accurate flow characteristics and noise attenuation. In hydrotreating applications, hydrogen can be released in an accurate way to downstream users or in an emergency to flare. This is important as hydrogen is a valuable commodity in the refinery and wastage needs to be kept to a minimum.

The valve also has Class VI shut-off (API 598), again reducing any possible leakage. It is generally supplied with fast opening actuators, and smart positioners.
