DUALVENT

Double-seated valve

200/280

DUALVENT is a double-seated valve that is used for more severe applications.The ARCA double-seat control valve is characterized by its simple and robust design, featuring a double-guided trim, and is used for larger volumetric flows. The flow is controlled at two ports, whereby both plug diameters are coordinated such that the medium exerts an opening force on the one plug and a closing force on the other and the actuating forces almost compensate each other out as a result. The plugs can take a variety of shapes to meet application requirements.

This is what distinguishes DUALVENT double-seated valve:

Multifunctional positioner
Flexibility thanks to the ARCA modular system
Robust precision trims
Pressure and thus force are balanced
Very low actuating force
High functional reliability even under adverse operating conditions

Firstly, the DUALVENT control valve is a double-seated valve designed for severe industrial applications. Therefore, it handles demanding media efficiently.

Moreover, the double-seated trim regulates the medium at two throttle points. As a result, the two control plug diameters work together so that one plug opens while the other closes, minimizing actuating forces.

In addition, the valve can be precisely aligned to your process and the dirty medium. This flexibility results from the wide choice of materials, connection options, and versatile trims.

Furthermore, shaping of the control plugs improves performance and durability. Consequently, the valve operates reliably even under tough conditions.

Moreover, the multi-stage, double-seated trim avoids cavitation. Therefore, it prevents shock waves and erosion damage to the valve body and internal parts.

Finally, our complete program of actuators and controllers supports seamless operation of the DUALVENT double-seated valves.
