Regulating Valves
Electro-pneumatic control valves create a pressure level corresponding to the respective requirement from an existing supply pressure or supply vacuum. Usually pulse width modulation (PWM) is used for this purpose. The output value depends on the duty cycle according to the respective valve characteristic.
Specially optimized cycled boost pressure control valves are a very cost-effective solution to adjust the wastegate of exhaust gas turbochargers. Since the boost pressure itself serves as supply pressure, no additional effort is required for pressure supply. Various versions are available for boost pressures up to 3.5 bar.
Vacuum Regulating Valve (VRV)
Highlights Vacuum Regulating Valve (VRV)
Vacuum regulating valves (VRV) are suitable for all control tasks with negative pressure. The most common application in the automotive sector is the control of turbochargers with variable turbine geometry or wastegate. However, there are also applications in the field of industrial vacuum technology, such as vacuum grippers.
Due to the integrated temperature compensation, the behavior of the VRV is almost independent of the temperature in a wide range, which significantly simplifies the control. Depending on the design, control is possible down to a vacuum of -90 kPa with very low air consumption. The modular principle allows individual adaptation to almost any application in a simple way.
Pressure regulating valves use similar components as the vacuum regulating valves. The control range extends up to a pressure of 300 kPa at supply pressures of up to 10 bar.
