产品详情
high-capacity control geometry engineered for large process or utility lines
the actuator positions an engineered trim to change flow; correct sizing depends on required capacity, installed pressure drop, process dynamics, phase behavior, noise, and the specified fail action; verify dynamic stability and line load
cooling-water control, air systems, large plant headers, and high-flow circulation loops
actuator force, dynamic stability, line load, noise, maintenance lifting plan, required Cv, and installed characteristic
