产品详情
a pneumatic diaphragm actuator that drives a globe-style throttling trim
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 rangeability and fail action
steam, water, gas, chemical dosing, and general process control loops
Cv, rangeability, fail action, air supply, trim characteristic, noise, cavitation, and positioner signal
