The Advantages of 2 Way Motorized Ball ValveValves Study | Sep.23.2020
COVNA GROUP manufactures 2 way motorized ball valve over 20 years. We provide different types, sizes, materials voltages motorized valves. So, let me introduce what are the advatages of the most popular 2 way motorized ball valves:
1.The external leakage is completely blocked, the internal leakage is easy to control, and the use is safe. Internal and external leakage is an element that endangers safety.
Other automatic control valves usually extend the valve stem, and the rotation or movement of the valve core is controlled by an electric, pneumatic, or hydraulic actuator. This must solve the problem of external leakage of the dynamic seal of the long-acting valve stem; only the electric two-way valve is completed by using electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve. There is no dynamic seal, so the external leakage is easy to block. Electric valve torque control is not easy, and it is easy to produce internal leakage, or even pull off the head of the valve stem; the structure of the electric two-way valve is easy to control internal leakage until it drops to zero. Therefore, the electric two-way valve is particularly safe to use, especially suitable for corrosive, toxic or high and low temperature media.
2.Simple system, just connect to the computer, low price.
The electric two-way valve itself has a simple structure and a low price. It is easier to install and maintain than other types of actuators such as control valves. What’s more obvious is that the composed automatic control system is much simpler and the price is much lower. Since the electric two-way valve is controlled by the switch signal, it is very convenient to connect with the industrial computer. In today’s era when computers are popular and prices have fallen sharply, the advantages of electric two-way valves are even more obvious.
3. Fast acting, samll power, light shape.
The response time of the 2 way motorized ball valve can be as short as a few milliseconds, and even the pilot-operated electric two-way valve can be controlled within tens of milliseconds. Since it is a self-contained circuit, it is more sensitive than other automatic control valves. A properly designed electric two-way valve coil has low power consumption and is an energy-saving product; it can also be used to automatically maintain the valve position by simply triggering the action without consuming electricity at all. The electric two-way valve is small in size, which saves space and is light and beautiful.
4. The adjustment accuracy is limited and the applicable medium is limited.
Electric two-way valves usually have only two states on and off, and the spool can only be in two extreme positions and cannot be adjusted continuously. (There are many new ideas trying to break through, but they are still in the trial stage) so the adjustment accuracy is still limited. The electric two-way valve has high requirements for the cleanliness of the medium, and the granular medium cannot be used. If it is impurities, it must be filtered out first. In addition, viscous media cannot be applied, and the viscosity range of the media for specific products is relatively narrow.
5. Diverse modes,widely uses.
Although the electric two-way valve has inherent shortcomings, the advantages are still very prominent, so it is designed into a variety of products to meet various needs and have a wide range of uses. The advancement of electric two-way valve technology also revolves around how to overcome congenital shortcomings and how to better exert inherent advantages.
