Valves

EH Series control valves (figure 9) are large,

high-pressure globe valves that incorporate proven

techniques in flow-stream contouring and in seat ring

and valve plug design. These features, along with

rugged cage guiding and hardened trim materials,

make the EH Series valves reliable high-capacity valves.

These valves are used for many high-pressure

applications in the power, process, oil production,

chemical, refining, and other industries. The EHD valve

(figure 8) is well-suited to general applications where

extremely tight shutoff is not required, and the EHT

valve (figure 10) offers up to Class V shutoff for

applications with relatively low process temperatures.
