DHR181 is a type of actuator product from the range of electric-actuated valves manufactured by Emerson. This type of actuator is designed for use with on/off and regulated control valves and is available in both pneumatic and electric versions. It is a versatile, rugged and cost-efficient solution for many types of applications. The actuator features a robust construction with an excellent performance-to-price ratio, making it a good choice for many industrial and commercial applications.

The DHR181 electric-actuated valve is designed to provide accurate and consistent control of any type of process valve. It operates without the need for compressed air or gas and is therefore an economical and effective method of controlling various types of processes. The design of the valve has been constructed to deliver an accurate response, low maintenance requirements and reliable operation. It is suitable for both on-off and modulating valve applications and can be used in a wide range of industrial processes such as chemical, pharmaceutical, food and beverage, mining, oil and gas, power generation, and mass production.

The DHR181 is constructed using aluminum alloy and stainless steel components, with a lightweight, compact design that helps to reduce the size and total weight of the actuator. The use of an internal spring configuration ensures that the output force is consistent and predictable, and that the actuator will remain stable in long-term working conditions. The actuator is also designed with input voltage tolerance protection so that it is able to work in a wide range of voltage conditions. It also features Electronic Overload Protection (EOP) to protect the actuator from overloads, as well as input and output indication LEDs which provide an indication of the status of the actuator at any given time.

The working principle of the DHR181 electric-actuated valve is quite simple. When the valve is powered, the motor is engaged, causing the valve to open or close. As the valve is actuated, the actuator will experience a force, which is applied to the stem of the valve, either opening or closing it, and thereby controlling the flow of the process. The degree to which the valve is opened or closed is determined by the amount of force applied to the stem, depending on the requirements of the application. The actuator features a variety of switches and feedback sensors, allowing the degree of opening or closing of the valve to be precisely controlled.

In conclusion, the DHR181 electric-actuated valve is an excellent cost efficient solution for many types of industrial and commercial applications. It offers reliable and accurate control of process valves, with a lightweight, compact design that helps to minimize installation costs. This type of actuator offers a range of features, including overload protection, input and output indicator LEDs, and can be used in a variety of applications, from chemical and pharmaceutical production, to mining, petroleum and power generation.
