EcoReve®
Installed on pneumatic rotary actuators (such as pneumatic ball valves/butterfly valves/plug valves), it converts the 4-20mA electrical signal output by the DCS/PLC system into an air pressure signal, accurately controls the rotation opening of the valve, and achieves closed-loop automatic regulation of medium flow and pressure in industrial pipelines. It is widely used in automation control systems such as petroleum, chemical, power, and water treatment.
Advantages:
·Extremely high adjustment accuracy: adopting closed-loop feedback control, the valve opening error is ≤± 1%, which can achieve precise proportional adjustment of 0-100% full stroke, meeting strict process requirements.
·Extremely fast response speed: millisecond level signal response, can quickly follow changes in control instructions, effectively suppress valve oscillation, and improve system dynamic adjustment performance.
·Strong anti-interference ability: With built-in filtering and anti vibration design, it can operate stably in strong electromagnetic interference and vibration environments in industrial sites without signal drift.
·Wide adaptability: The standard interface can directly adapt to the vast majority of pneumatic rotary actuators, supporting multiple adjustment modes such as forward/reverse action and split range control, and adapting to different working conditions.
·Easy to operate and debug: Equipped with an intuitive opening indicator and pressure gauge, zero and range calibration can be quickly completed without the need for professional tools, resulting in high debugging efficiency.
·Excellent explosion-proof performance: Complies with intrinsic safety/explosion-proof standards, can be directly applied to hazardous conditions such as flammable and explosive chemicals, oil and gas, and is safe and compliant.
·Stable and durable operation: The fully sealed structure has a high level of protection, is resistant to dust, moisture, and corrosion, has a long maintenance free cycle, and has high long-term reliability.
·Significant energy saving and consumption reduction: only consumes gas during valve operation, with zero static gas consumption, significantly reducing compressed air energy consumption and lowering system operating costs.
