CHX(EP)-724AH electric valve positioner CHX brand  NE724/S1 ELECTRO-PNEUMATIC POSTIONER 

 

chx700 type electric valve positioner converts the DC signal of 4-20 ma from the regulator or computer io port into aerodynamic force  ,  and drives the regulating valve by single or double acting cylinder to realize angular displacement or linear displacement. The closed loop control is realized through the cam feedback system, which makes the regulating valve realize accurate angular displacement or linear displacement proportional to the input signal.

- Standard input signal 4~20 ma dc 0~20 ma dc

- Range 4~12 ma dc 12~20 ma dc

- Input impedance 220ω±10ω

- Feedback angle 95°

- straight trip :  mm 20-140

-  control direction positive and counterproductive

- The relationship and  linear about trip and signal 

- Supply pressure 0.14~0.8 mpa

- Pressure <0.2%/10 kpa on supply

- ambient temperature -25~85℃ -≤0.05%℃ environmental temperature

- Class ip54 of Protection

- gas consumption 0.5 m3n/h 

φ4,φ6 of servo slide valve matching actuator

Performance when actuator loads are relatively stable

- dead zone ≤  -0.4%

- lag <  0.7%

- linear<±1%

-  Vibration effects (1.5 g –100hz)≤1%
