Pneumatic pneumatic valve positioner output air pressure changes

Pneumatic pneumatic - valve under the condition of particularly high temperature, can choose ceramic materials, including silicon carbide ( 原文如此) High strength, high hardness, thermal stability and oxidation resistance are superior, has the very good high temperature strength, wear resistance, corrosion resistance, creep resistant performance is good. Pneumatic pneumatic - valve when the input signal changes or changes, such as dielectric fluid forces force balance system balance is broken, magnetoelectric component force and feedback loop caused by the valve stem position change of forces is in a state of imbalance, because of the nozzle and the baffle, the locator air output pressure change.
