Valve Positioners

This dust and gas explosion-proof valve positioner features Ex db IIC T4~T6 Gb for gas protection and Ex tb IIIC for dust protection with IP66 protection. It offers 0.5% F.S. positioning accuracy and supports 4-20mA DC input with HART7 communication. Built with an auto-tuning function for valve zero and span optimization, it includes self-diagnosis for current values, travel time, and deadband. Its 3-off position safety function (full open, full close, hold, manual) eliminates the need for external solenoid valves. With static air consumption below 36L/h and a compact 3.2kg design, it ensures energy-efficient and reliable operation.

This explosion-proof valve positioner features an Ex db IIC T4~T6 Gb rating and IP66 protection. It comes with LCD display and auto-tuning function for convenient on-site configuration. It supports 4-20mA DC input with HART, Profibus PA, or FF bus communication. Built with a magnetic induction contact sensor and integrated encapsulated circuit module, it delivers precise valve control algorithms. The 3-off position function (power-off, air-off, signal-off) eliminates the need for external solenoid valves. With static air consumption below 36L/h, it ensures energy-efficient operation in harsh environments.

This intrinsically safe valve positioner features an Ex ia IIC T4~T6 Gb rating and IP66 protection. It is equipped with LCD display and auto-tuning function for convenient on-site setup. It supports 4-20mA DC input with HART, Profibus PA, or FF bus communication. Built with a magnetic induction contact sensor and integrated encapsulated circuit module, it offers precise valve control algorithms. Its 3-off position function (power-off, air-off, signal-off) eliminates the need for external solenoid valves. Static air consumption is less than 36L/h, making it highly energy-efficient.
