Answer Posted / rakesh kumar .n be
for high pressure application we use the the bigger actuator is wrong concept, mostly in the early days days we used this kind of actuator, mostly used for diaphragm and piston type actuator , if u use diaphragm type then u need big cascade, for high pressure , but we should change the cascade for regular intervel. in our company we control the 220 kg/cm2 of pressure in the small actuator only, bigger actuator is disturbance only large space is needed and difficult to calibrate. thanks
