Proportional pressure valves are an important component in many industrial applications where precise pressure control is required. They enable precise control of printing in one system, providing a variety of benefits for different industries.
A proportional pressure valve consists of a solenoid controlled coil that regulates the flow of fluids in a valve. By adjusting the electrical signal sent to the coil, the pressure in the system can be controlled. This allows precise control of the pressure, regardless of the fluctuations in the system.
A major advantage of proportional pressure valves is their high accuracy. You can precisely control the pressure with a resolution of up to 0.1%. This is especially important in applications where the pressure must be maintained at a certain level to ensure optimum performance. For example, in the automotive industry, where proportional pressure valves are used in vehicle brakes to ensure the correct brake pressure.
Another advantage of proportional pressure valves is their fast response time. You can react to changes in the system within milliseconds and adjust the pressure accordingly. This is particularly important in applications where fast responses are required, such as robotics or hydraulic presses.
In addition, proportional pressure valves offer a high degree of flexibility. They can be adapted to different requirements by combining them with various controls and sensors. This allows individual adaptation to the specific needs of an application. For example, proportional pressure valves can be used in medical technology to regulate the pressure in medical equipment such as ventilators or dialysis machines.
Another important aspect of proportional pressure valves is their energy efficiency. Precise control of the pressure optimizes energy consumption and prevents unnecessary energy loss. This is particularly important in applications where large amounts of pressure are required, such as in the energy industry or heavy industry.
Overall, proportional pressure valves offer a precise, fast and flexible solution for pressure control in industrial applications. They are widely used in many industries and play an important role in optimizing the performance and efficiency of systems. With their high accuracy and response time, they offer significant added value for companies that rely on precise pressure control.

What are proportional pressure valves and how do they work?
Proportional pressure valves are a type of hydraulic valve that controls the flow of hydraulic fluid in a system. They are used in various applications, such as in industry, automation technology or mobile hydraulics.
The operation of a proportional pressure valve is based on the principle of proportionality. The valve regulates the pressure in a hydraulic system by controlling the flow of fluid according to a specific ratio. It can increase or decrease the pressure depending on the requirements of the system.
A proportional pressure valve consists of a pressure control unit and a proportional control unit. The pressure control unit contains a spring and a piston system that regulates the pressure of the hydraulic fluid. The control unit consists of a proportional solenoid that moves the piston in the pressure control unit.
The control unit of the valve is activated by an electrical signal that activates the proportional solenoid. Depending on the strength of the signal, the piston in the pressure control unit moves and regulates the flow rate accordingly. The valve can continuously control the pressure by positioning the piston depending on the control voltage.
Proportional pressure valves enable precise control of the pressure in hydraulic systems and offer a high degree of flexibility. They can be used in combination with other valves to implement complex control systems. By precisely regulating the pressure, they can also enable energy savings and improve the efficiency of a system.

How are proportional pressure valves controlled and regulated?
Proportional pressure valves are usually controlled and regulated by an electronic control unit. This control unit is connected to a sensor that measures the current pressure value and reports it back to the control unit.
The control unit then compares the measured pressure value with the desired setpoint value and calculates the corresponding valve opening to regulate the pressure to the desired value. This is done by adjusting the control current that controls the valve.
The control unit can communicate with a higher-level control system either via an analog or digital interface. Parameters such as the setpoint, the control parameters and other settings can be transferred via this interface.
The control unit can also have a feedback loop that continuously compares the actual pressure value with the setpoint value and adjusts the valve opening accordingly to correct deviations.
In addition to control and regulation, proportional pressure valves can also have a safety device that automatically closes or opens the valve in certain situations to prevent damage or malfunctions.
