Embrace the ease of AUKEMA actuators featuring two non-intrusive magnetic control knobs. The 'mode' knob offers three distinctive positions: 'local', 'remote', and 'stop'. Meanwhile, the 'operation' knob provides precise control with 'open' and 'close' options. When set to 'local', simply turn the operation knob to your desired position to command the actuator's movement. Choose between two local control modes: 'jog' for precise adjustments or 'hold' for sustained operation.

2.8 Remote Control
Seamlessly integrate the field actuator with your DCS or PLC through a durable hard-wired cable, enabling control via switch quantity (manual) or current quantity (automatic) operations.
Our advanced switch quantity control system encompasses three input terminals: valve opening, valve closing, and stop/hold. Customize your operation further by selecting inching or holding modes. Additionally, auxiliary switch quantity control ensures emergency protection (ESD) and incorporates valve opening and closing interlocks. For enhanced reliability, remote input is photoelectrically isolated, boasting the capability to withstand surges up to 2.5KV.
The remote analog quantity control proudly features a sophisticated linear optocoupler isolation method, ensuring precise valve positioning as per the input analog quantity signal ratio. This high-tech solution guarantees seamless and accurate control, enhancing operational efficiency.
The remote analog valve position feedback mechanism empowers the system by sending the valve position directly to the DCS or PLC via a robust 4-20mA signal. Additionally, users can opt for remote analog feedback for torque, providing comprehensive monitoring capabilities.

2.9 ESD Control
In critical situations, the ESD signal possesses the authority to override any local or remote signals (based on parameter configurations) to decisively command the actuator to either close or open the valve. The ESD action can be selectively configured to 'close the valve', 'open the valve', or 'hold position', offering unparalleled safety assurance.

2.10 Interlock Control
For demanding and complex applications, the actuator is expertly configured for conditional control, meeting the highest standards of operational flexibility and reliability.
In this advanced mode, the actuator's operation hinges on the presence of two independent signals. For instance, upon receiving a simultaneous remote close input signal and a close interlock input signal, the actuator will execute a valve closure. If only one signal is active or a signal is lost, the actuator will hold or halt, effectively preventing any operational failures. For ESD-required applications, a dedicated ESD input is made available, taking precedence over any local or remote control signals to ensure safe operation.

Q7: What are the advantages of your company? (Price, special accessories, product quality)
* The company's main products are electric actuators, which are equipped with valve products. Our company was established for 13 years. We founded the (Changneng) brand electric actuators and later founded the (AUKOMA) brand high-end series electric actuators. After more than ten years of market operation, the product quality and market sales are stable, and we have a certain reputation in the domestic industry. Our brand is medium in China, and our product series is relatively comprehensive. We have Z, Q, CND, AK series products that can compete with domestic first-line products, and AK series products that can replace international brands. There are great advantages in cost performance.
Let's talk about what this electric actuator is used for. The electric actuator controls the opening and closing of the valve, and the valve controls the opening and closing of the pipeline. Valves include manual valves, electric valves, pneumatic valves, electro-hydraulic valves, etc. With the improvement of industrial automation, more and more automatic control valves such as electric valves or pneumatic valves are used on pipelines that originally used manual valves. Electric valves require our electric actuators, which means the actuators are the brains of electric valves. After using electric actuators, the valves can be switched on and off through on-site electric buttons or remote computer systems, thereby controlling the on and off of the pipelines.

Q8: Does the price change every month or is it fixed?
*The price is fixed. Without special reasons such as a sharp increase in raw materials, the price will generally not change.

Q9: Is it in stock or produced after orders? If the production is after the order, how long will it take to produce? Delivery time?
*Export products have different requirements for materials, packaging, etc. They will be produced according to orders.
*Generally, it takes about 10 days for less than 50 units and 20 days for less than 100 units. The production cycle of AK high-end series will be slightly extended.

Q10: What material is this product made of?
*The product has two types of materials: iron shell and aluminum shell. The aluminum shell is small and the small size of the AK intelligent series is aluminum shell, and the conventional model and large size are cast iron. The large size has a large output torque, and the cast iron shell is used because cast iron has a strong pressure bearing capacity.

Q11: Are we currently doing OEM with other brands?
*We do OEM for several domestic units, and we aslo accpet OEM oreders.

Q12: Have we done any relatively large and well-known enterprise projects?
*Our products are used in major domestic steel mills, power plants, water plants (sewage, tap water), coal mine water treatment, coal mine gas extraction, petroleum and petrochemicals, etc.

Q13: Does this product have a service life?
*Yes, the service life is related to the switching frequency of the valve. The valve is installed on the pipeline, and the electric actuator is a device that controls the valve switch. If the valve switching frequency is very high, the actuator will be used more frequently, and the internal gears and turbines, worms, nuts, etc. will have certain wear, but it is much longer than the service life of the valve. Some valves on pipelines need to be replaced after a few years. Generally, the actuator will be replaced at the same time as the valve. At present, our products are used on pipelines, and many actuators from more than 10 years ago are also in normal use.

Q14: Can parts be replaced if the product is damaged?
*It can be replaced. Generally, the limit switch that controls the valve opening and closing is a high-frequency component and may need to be replaced.

Q15: How much does the factory produce per month?
