in a electronic controller why we are using 250 ohm resistance in input signal?is i/p is necessary in control valve when we are using electronic controller give details?
During valve sizing from all calculation you got flow coefficient CV 12,than what it means? like for selecting pressure transmitter if your MAWP is 12 bar than you select a capsule of max. 20 bar which cover your mawp 12 in same way for selecting control valve If CV is 12 than how we use it in selecting valve??????1 3410
