Control Valves
For precise,stepless control
of flow and pressure.
What is a control valve?
A control valve is not designed for simple on/off operation, but for precise, continuous modulation of media flow. By accurately positioning the valve cone, flow rates, pressures, or temperatures can be maintained at a defined setpoint throughout the process. This level of control is essential for ensuring efficiency and product quality in automated systems.
