A pneumatic cast iron butterfly valve is a type of device controlled by a pneumatic system, consisting of a butterfly valve combined with a pneumatic actuator. Compressed air is supplied and distributed through a solenoid valve into the actuator, pushing the piston to move along its full stroke. This generates torque on the screw shaft, causing the valve stem to rotate 90 degrees and completing the opening cycle. The same process applies to the closing cycle (for double-acting types).
For single-acting types, the spring force performs the closing cycle. These valves operate relatively quickly and do not require manual operation, making them ideal for saving human resources and time.

Advantages and Applications of Pneumatic Cast Iron Butterfly Valves
Advantages
Fast Operation: As one of the most popular pneumatic control valves today, it offers rapid open/close times of about 1-3 seconds, enabling quick flow control and regulation.
Cost-Effective: These valves are relatively affordable with a wide range of product options. Current pneumatic cast iron butterfly valves provide various segments to suit different needs and budgets.
High Quality: The products are highly rated in the market. The butterfly valves used are from the Wonil brand (Korea), while the pneumatic actuators are from KosaPlus (Korea) and Haitima (Taiwan).
Wide Size Range: These valves can accommodate almost any butterfly valve size, allowing pneumatic actuators to be installed for control.
Versatile Actuators: Compatible with pneumatic actuators from Taiwan or Korea. Each brand offers both single-acting and double-acting actuators for greater flexibility.
Stable and Reliable: They operate stably and do not pose risks like short circuits, which can occur in electrically controlled valves.
Environmentally Friendly and Safe: Using compressed air as a clean, eco-friendly energy source ensures safety for people and the environment.
Easy Installation: The valves connect easily to pipelines, whether flange-type or wafer-type butterfly valves. They can be installed on any standard flange.
Space-Saving Design: They require less space compared to ball valves or gate valves.
Fully Automated: The valves can be remotely controlled by integrating additional components such as pneumatic solenoid valves, limit switches, or positioners into the pneumatic actuator system.
Applications
Water Supply and Treatment: Used for regulating and controlling pneumatic systems in clean water production and water treatment facilities.
Pneumatic Systems in Automation: Regulate air flow in automated systems supplying air for manufacturing processes.
Wastewater Management: Operates in treated wastewater systems to control flow.
Irrigation Systems: Used for flow control in irrigation and agricultural water systems.
Agriculture: Automates water supply for agricultural needs.
Livestock Farming: Controls water systems in industrial livestock farms for automatic regulation.
