Valves are pretty widely used in systems such as hardware, processing, facilities and equipment’s. Technically, its role is dispensable: used for fluids, liquids or gases direction by turning on or off the flow through its section or entire pipeline. Its market value reflects in almost all economic entity and industry, its main usage include chemical cooling or refining, water management, manufacturing and engineering and so on. The oil and gas sector has high demand on valves due to the specialty materials protection function. It can protect against the various caustic and hazardous produced and handled liquids and gases.
A wide range of synthetic materials including plastics, fiberglass and metals can be used as valves material. Actuators especially electric actuators can be thought as an automated or remotely-controlled valve. It can be remotely-controlled, such as on pipelines, when manual operation of the valve is not possible. The application of electric actuators has a lot of impact on plastic valves market.
Electric actuators are easily used you should know that because they are easy to interface with the control systems which are also electric. Its advantages include: electric working pattern smooth’s the actuation work, simple control mechanism, using the clean energy, simple fault diagnose. Also, electric actuators’ integration is easier with remote controls. In special condition only, the maintenance needs less even no parts replacement or lubrication.
Nowadays, there are two electric actuators’ products that applied widely in many enterprises: industrial linear actuator and precision linear actuator. Industrial linear actuators are electric actuators that works in a typical open loop which powered by 12, 24, 36 or 115, 230, 400 VAC. It is a well- performed electric actuators in construction, mining, industrial facilities and equipment to control components like doors, throttles and any other related device. In some case, it performs excellently in medical, healthy or fitness facility and entertainment device.
The later electric actuators application is precision linear actuator. It is another sort of electric actuators of which cylinders operated in AC drive controlled closed loop systems. Referring to its name, it is specifically designed for high precise demand. High performance like high speed and force capacities push-rod applications where positioning accuracy are a must for its function.
To most valves, their practical performance is partly depended by its material. Plastic is a relative cheap material in manufacturing industry and its insulate attributes contributes its advantages. For electric actuators, it means more than common valves. The electric remote control function raised the demand on insulation. On the other hand, with more sustainable development policy published by the government, the electric actuators occupied an increasing part of Plastic valves market. In America, companies like Thomson are engaging to manufacture the electric actuators. As more users are benefited by its distinguished performance characteristics, its price is increasing progressively.
To gain the competitiveness in current market, more and more enterprises and manufacturing companies are using plastic valves products like electric actuators. The application of electric actuators is also attracting people’s attention due to its high performance. For your future benefit in current competitive environment, applying electric actuators in your automation system is an considerable issue.
