If you work in a field or industry that requires precise control of flow through pipelines, valves are an essential component. Valves help control the flow of liquids, gases, and steam through a pipeline or other types of systems. For valves to work effectively and efficiently, they need actuators. An actuator is a device that converts energy into motion or physical displacement, helping valves to do their job.
Electric valve actuators have become increasingly popular as an alternative to traditional hydraulic and pneumatic actuators. They offer numerous benefits, such as greater accuracy, lower maintenance costs, and increased efficiency. In this blog, we will explore all you need to know about electric actuators, eccentric semi ball valves, and how they work together to provide optimal fluid control.
What Are Electric Valve Actuators?
An electric valve actuator is a device that uses electrical energy to actuate valve movement. The actuator's motor and control circuit are responsible for moving the valve. Electric actuators are often chosen because of their high accuracy, constant torque, and low maintenance compared to hydraulic actuators. There are two types of electric valve actuators: rotary and linear. Linear electric actuators are mostly used for gate and globe valves, whereas rotary electric actuators are more suitable for ball, butterfly, and plug valves.
What Are Eccentric Semi Ball Valves?
Eccentric semi ball valves are a type of ball valve that offers several advantages over traditional ball valves. They feature a unique design that provides eccentricity, resulting in a cam-like lifting effect on the ball, which ensures leak-tight shutoff at low and high pressures. This characteristic makes them ideal for process applications that require frequent shutoffs, such as in the chemical and petrochemical industries. Eccentric semi ball valves are also known for their reduced operating torque, resulting in less energy consumption and wear on electric actuators.
How Do Electric Valve Actuators Work with Eccentric Semi Ball Valves?
Electric actuators and eccentric semi ball valves are often paired together to provide precise control over fluid flow in pipelines. The valve's unique design allows it to provide a cam action, slightly lifting the ball off the seat to reduce friction, which results in reduced operating torque on electric actuators. When an electric actuator receives a signal, the motor drives the valve stem, rotating the ball to an open or closed position, depending on the desired flow rate. The electric actuator then returns to its "off" position, maintaining constant torque and ensuring the valve stays open or closed.
In Conclusion
Electric valve actuators and eccentric semi ball valves offer numerous advantages over traditional hydraulic and pneumatic actuators and ball valves. Their unique design and functionality provide precise and efficient fluid control, reduced operating torque, and lower maintenance costs. When considering options for fluid control systems, electric actuators and eccentric semi ball valves should not be overlooked for their performance and reliability benefits. By partnering with the right supplier, your company can achieve optimal fluid control with increased efficiency and reduced costs.
