DUALVENT is a double-seated valve that is used for more severe applications. The double-seated trim regulates the medium at two throttle points. The two control plug diameters are matched to each other in such a way that the medium has an opening influence on one control plug and a closing influence on the other control plug, and the actuating forces thus are minimized. Thanks to the variety in the choice of materials, the connection to the piping system or the versatile trims, the control valve can be precisely aligned to your process and the dirty medium. This also applies to the shaping of the control plugs. The option of a multi-stage, double-seated trim also avoids cavitation that could lead to shock waves and erosion damage to the valve body and internal parts. You are on the safe side with the DUALVENT control valve, even with tough applications. Of course, our complete actuator and controller program is available for the actuating of the double-seated valves.
