Electrical-pneumatic valve converter
CHX(HEP) Electric valve locator |
| | Summary CHX(HEP) electric valve locator that can change electrical signal outputed by regulation equipment into driving air signal of control valve action, and with valve positioning function to overcome stem friction and to offset balance force caused by pressure change controlled, then to control signal and realize corrective location |
| Technical parameters and performance | Input signal: standard 4~20mA DC split range: 4~12mADC, 12~20mADC 10~50mADCInput impedance: 250Ω(4-12mADC)100Ω(10-50mADC)Air pressure: 0.14~0.16MPa 0.17~0.5MPaRated travel: Direct travel: 12-100mm rotation: 0-90°Conductor joint: M22×1.5 internal thread(G1/2)Air source joint: ZG1/4Ambient temperature: flameproof type: -20~+60°C ordinary type: -20~+80°C Relative humidity: ≤90%Return difference: less than full travel 1%Dead band: less than full travel 0.4% Performance: linear (Quick open, equal percentage characteristic changeable) Gas consumption: 5L/min (when air source pressure is at 0.14Mpa) Flow: 140 L/min ( when air source pressure is at 0.14Mpa) Weight: 3.5Kg |
