When the actuator is at the closed limit and initiates an opening action, the torque protection feature will temporarily pause. During this period, the motor delivers maximum torque to release a stuck valve. Should the valve remain immobile after this interval, the system will prudently cut off power to prevent damage, optimizing both performance and safety.
f. Motor Overheat Protection: Relish in the reliability of dual temperature regulators that vigilantly oversee the motor coil's temperature. Upon detecting overheating, these sensors swiftly disengage the actuator's control circuit, ensuring the motor operates within safe limits and prolonging its lifespan.
g. Instantaneous Reversal Protection: Ensure durability and efficiency with our instantaneous reversal protection. When a quick reversal command is issued, an automatic delay circuit mitigates the impact load, reducing wear on the valve stem and gearbox. This circuit also effectively limits surge currents through the contactor, fostering long-term reliability.
h. Automatic Self-Detection and Diagnosis Function (ASTD): Enjoy the convenience of continuous assurance with our ASTD feature. Once power is supplied, the actuator autonomously evaluates the operating circuit for accurate functionality. In the rare event of equipment failure, it diagnoses and instantly displays faults on-screen using clear icons, simultaneously inhibiting valve actuator operation, streamlining on-site maintenance like never before.
i. Data Record Protection: Securely preserve crucial parameters with our advanced data record protection. Even when the main power supply is interrupted, the valve actuator retains vital parameters in the resilient EEPROM, safeguarding your data for an impressive period of up to 20 years, providing unmatched peace of mind.

2.9 ESD control
In critical situations, our ESD control mechanism takes command, prioritizing safety. It can override any current local or remote signals as per the configured parameters, compelling the actuator to either close or open the valve. Select from options like 'close the valve,' 'open the valve,' or 'hold position' for tailored operational control in emergencies.
2.10 Interlock Control
For high-demand scenarios, configure the actuator for conditional control to meet exacting requirements with precision and reliability.
The conditional control mode ensures operations are contingent upon two independent signals. For instance, if both a remote close input signal and a close interlock input signal are detected simultaneously, the actuator will close the valve. In the absence of one signal, the actuator maintains its position or halts to avert failures. A dedicated ESD input is available for applications needing emergency shutdowns, overriding any local or remote controls for utmost priority.

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?
*1,200-1500 sets per month.
Q16: What is the payment methods accepted?
*We accpet TT, Paypal, West Union, World First, Alipay, Wechat Pay etc.
