Pneumatic control valves, directly controlled
Pneumatic control valves are an important component in pneumatic systems as they can regulate the flow of compressed air to specific areas. There are several types of control valves, one of which is direct operated valves.
Direct operated valves are valves where the pilot pressure acts directly on the valve to regulate the flow. They are usually simple in design and have high reliability. Their structure consists of a housing, a diaphragm and a seat. The flow is controlled by the movement of the diaphragm, which opens or closes the seat.
The advantage of directly controlled valves is their fast response time. Since the control pressure acts directly on the valve, the regulation of the flow takes place almost in real time. This enables precise control and fast response to changes in the plant. Direct operated valves are therefore ideal for applications where fast and accurate flow control is required.
Another advantage of directly controlled valves is their ease of use. They can be easily integrated into pneumatic circuits and do not require complex controls. This makes them cost-effective and easy to use. They also require little maintenance and have a long service life.
Directly controlled valves are used in a wide range of applications, for example in automation technology, in the food industry, in medical technology and in the packaging industry. They are used in processes such as opening and closing valves, controlling cylinders and regulating compressed air flows.
When selecting a direct operated valve, it is important to consider the specific requirements of the application. Factors such as the maximum allowable pressure, the flow range, the size of the valve and the type of media play a role. There are different types of direct operated valves, such as 2/2-way valves, 3/2-way valves and 5/2-way valves, each with different functions.
Overall, direct operated valves provide an effective and reliable solution for controlling compressed air in pneumatic systems. Their fast response time, ease of use and wide range of applications make them a popular choice in various industries. Thanks to their precise control and high reliability, they help optimize processes and increase efficiency in pneumatic systems.

How does the direct control of pneumatic control valves work?
Pneumatic control valves are usually controlled directly using compressed air. The compressed air is fed directly to the control valve to perform the desired function.
To open or close the valve, compressed air is fed to the valve's drive mechanism. This can be done via a compressed air line or a pneumatic control unit, for example. The pressure sets the valve's drive mechanism in motion and the valve opens or closes accordingly.
The compressed air is usually controlled via electrical signals. These signals are generated by a control device or a control unit and sent to the control valve. The control valve then processes the signals and controls the flow of compressed air accordingly.
When directly controlling pneumatic control valves, it is important to use the correct pressure range and the correct amount of compressed air to ensure precise control. The valves should also be serviced and cleaned regularly to ensure optimum function.

What challenges can arise when using directly controlled pneumatic control valves and how can these be overcome?
Various challenges can arise when using directly controlled pneumatic control valves, including
1. Pressure loss: The use of control valves can result in a pressure loss as the flow through the valve is limited. This can lead to reduced performance. To overcome this problem, larger valves can be used to increase the flow or pressure compensation mechanisms can be implemented.
