Q1: Do you have any standard international certificates?
*We have ISO9001, ISO14000, CE, UL and other certifications. Our products also have sepcial deisgn patents.
Q2: Are there any special certification requirements for this product?
*There are certification requirements for explosion-proof actuators in China. They must have explosion-proof certificates and production licenses issued by the National Explosion-proof Electrical Inspection Center. By 2020, the production license will be cancelled and converted to 3C certification. Coal mine products have mining product safety mark certificates (referred to as coal safety certification) and mining product explosion-proof certificates. This coal mine certification product is our company's advantage product. At present, in the electric actuator industry, only 6 actuator manufacturers in China have such mining valve actuator certificates. Domestic coal mines must have products with this mining safety certificate to be used on pipelines underground in coal mines. Therefore, compared with other ground products, there will be less competition in the coal mine sector. Now the company's export of coal mine products is also rising year by year.
Q3: If this product can be operated using WiFi, are there any anti-theft wall measures?
*AK smart series has GPRS mobile phone card wireless control function, which is a special optional function with name, password and verification code to ensure security. This function is not widely used in China at present. It will be considered in some special areas where control cables cannot be laid but there is a signal network.
Q4: Does the factory have a CO Form E record?
*Yes
Q5: How long is the warranty period for this product?
*One year based on the date of manufacture.
Q6: How to start calculating the warranty period?
* According to the date of manufacture (the year and month of manufacture are on the product nameplate).
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?
*1,200-1500 sets per month.
Q16: What is the payment methods accepted?
*We accpet TT, Paypal, West Union, World First, Alipay, Wechat Pa
