Understanding Split Butterfly Valve Manufacturers Active and Passive Designs
In the world of industrial automation and fluid handling, butterfly valves play a pivotal role in controlling the flow of liquids and gases. Among the various designs, split butterfly valves have gained prominence due to their unique features and efficient performance. This article explores the differences between active and passive split butterfly valves and highlights key manufacturers in the industry.
What is a Split Butterfly Valve?
A split butterfly valve consists of two flaps or discs that come together to form a seal when closed, allowing for effective flow control. The split design refers to the valve being parted into two distinct components for easier maintenance and installation. These valves are versatile and are used in a variety of applications across industries including water treatment, chemicals, HVAC, and food processing.
Active vs. Passive Split Butterfly Valves
Active Split Butterfly Valves
Active split butterfly valves are designed to be operated using a mechanical actuator. This actuator can be electric, pneumatic, or hydraulic and allows for automatic control over the valve's position. This means that the valve can be adjusted remotely or through a control system, enhancing efficiency and enabling integration within automated systems.
The primary advantage of active valves is their ability to handle dynamic processes where precise flow regulation is necessary. Industries that often utilize active split butterfly valves include petroleum, power generation, and pharmaceuticals, where stringent regulations require tight control over flow rates and pressure.
Passive Split Butterfly Valves
On the other hand, passive split butterfly valves operate manually, relying on physical input from an operator to open or close the valve. While this means that they may not provide the same level of precision as their active counterparts, they are still very effective in applications where flow control does not need to be adjusted frequently.
Passive valves are generally more straightforward and cost-effective, making them ideal for various low to medium-pressure applications, such as irrigation systems and simple water flow management in buildings.
Major Manufacturers of Split Butterfly Valves
Several manufacturers specialize in producing high-quality split butterfly valves for various applications. Renowned names in the industry include
