Aluminum Alloy Electrical Valve Positioner CHX(EP)-700 Explosion Proof CHX-724 NES-724
Chx700 electric valve positioner converts the 4-20mA DC signal from the regulator or computer IO port into aerodynamic force, and drives the regulating valve through single acting or double acting cylinder to realize angular displacement or linear displacement. The closed-loop control is realized through the cam feedback system, so that the regulating valve can achieve accurate angular displacement or linear displacement proportional to the input signal.
- standard input signal 4 ~ 20 mA DC 0 ~ 20 mA DC
- split range 4 ~ 12 Ma DC 12 ~ 20 mA DC
- input impedance 220 Ω± 10 Ω
- Maximum feedback angle 95 °
- straight stroke 20-140mm
- positive and negative reaction of control direction
- linear relationship between stroke and signal
- gas supply pressure 0.14 ~ 0.8MPa
- influence of air supply pressure ＜ 0.2% / 10KPA
- ambient temperature - 25 ~ + 85 ℃
- influence of ambient temperature ≤ 0.05% ℃
- protection grade IP54
- gas consumption 0.5m3n/h
Servo slide valve matched with actuator φ 4, φ six
Performance when the actuator load is relatively stable:
- dead band ≤ 0.4%
- hysteresis ＜ 0.7%
- linearity ＜± 1%
Vibration influence (1.5g – 100Hz) ≤ 1%
The shell of the structural material is aluminum alloy with glutamic acid treatment and electrostatic powder spraying coating on the outer surface, the cover is polycarbonate, and the internal parts are stainless steel and aluminum alloy, which are corrosion-resistant materials and subject to surface technical treatment.
