| Valves with pneumatic actuators |
Valves with pneumatic actuators are devices used in industry to control the flow of fluids (such as liquids, gases, steam) in pipes. They play a crucial role in industrial processes, allowing automated control of the flow of a fluid in a pipeline, which is essential for several industrial applications.
How it works:
The pneumatic actuator is the part of the valve that converts the energy of compressed air into mechanical movement to operate the valve. When compressed air is directed to the actuator, it activates a mechanism that moves the valve plug, thus controlling the flow of fluid in the piping. Actuator control can be done manually or, more commonly, automated, through industrial control systems.
Types of Valves with Pneumatic Actuators:
Globe Valves with Pneumatic Actuator: They are used to control the flow in a pipeline. The movement of the globe-shaped shutter allows precise regulation of the flow.
Ball Valves with Pneumatic Actuator: They have a ball-shaped obturator that rotates to open or close the flow. They are common in applications where fast and efficient flow control is required.
Diaphragm Valves with Pneumatic Actuator: They have a diaphragm that moves to open or close the flow. They are often used in applications where fluid contamination must be minimized.
Pneumatic Actuator Butterfly Valves: The disc-shaped plug of a butterfly valve rotates to control flow. They are known for their quick opening and closing operation.
Pneumatic Actuator Control Valves: Specifically designed to precisely control flow in response to automatic control signals.
Check Valves with Pneumatic Actuator: Allow flow in one direction and prevent return in the opposite direction. The actuator can be used to control the positioning of the check valve.
Pneumatic Actuator Diaphragm Valves: They are designed with a flexible diaphragm that moves to allow or block flow. They are suitable for hygienic applications.
Safety Valves with Pneumatic Actuator: Designed to release or block the flow in emergency situations. They are critical in industrial processes where safety is a priority.
The choice of valve type with pneumatic actuator will depend on the specifics of the industrial application, the type of fluid, operating conditions and process control requirements. These systems are fundamental to industrial automation, providing precise control over fluid flow in a variety of industrial contexts. |
