Which imported electric actuator is relatively cheap?
Thread Content
Recently, a project required twenty to thirty explosion-proof electric actuators. I had only heard of Rotork before; after doing some research, I found that there are also other well-known brands such as EMG, AUMA, and Bernard. Which of these brands offers the better price-performance ratio?
It’s better to buy domestic products; imported ones are of poor quality, the service is terrible, delivery times are long, prices are high, and the support for accessories is inadequate.
Our factory uses Autoc; it hasn’t had any problems since 1967. Domestic electric valves offer a good cost-performance ratio as well as satisfactory after-sales service
Uh, why are all recommendations for domestic products? The company tried using a domestic product once and the results were very poor; now we have to use imported ones
Electric valves made in China are also quite good nowadays. It depends on your budget!
Pumps and valves are just a bunch of scrap metal. Explosion protection means that the outer wall is made of thick copper-like material, the seams are narrow enough, and the air permeability is low enough. Such a trivial thing as broken copper and scrap metal – why buy imported versions? There’s a serious lack of confidence in our own systems; it’s a waste of foreign exchange and money. :P OP, buy domestic products to save money, and use that money to date foreign girls – how great that would be! If you could even find a few foreign women to keep around, things would be even more interesting... That could be considered an act of love for your country 🈶. :lol
We used imported Sabos and Rotek before, but now we use the domestic Shanghai Shaner. It’s affordable and of good quality as well.
The brands mentioned are all relatively expensive, and they seem to be on par with each other. There are also many imported options; it depends on where they will be used – for ordinary uses, Korean brands are cheaper； Bernard has extensive experience in nuclear power applications. For small valves used in areas such as water treatment, Bernard currently has a production facility in Beijing that manufactures valves with low torque; these valves are not expensive.
