dualvalve

Dualvalve is a term used in engineering to describe a valve assembly that contains two independent valve elements within a single housing or module. The configuration is designed to manage two separate flow paths, two sequential control stages, or both, depending on the application. In practice, a dualvalve can take several forms, including two 2/2 valves mounted in a common body, a single valve with two seats and dual actuation, or a valve that provides dual actuation for a single seat.

Actuation methods for dualvalves vary and may include electric solenoids, pneumatic or hydraulic actuators, or manual levers. The dual elements can be controlled independently to enable complex logic or coordinated operation in a compact footprint, which can simplify piping and reduce installation time in automated systems.

Applications commonly involve automated machinery, process control, and systems requiring redundancy or compact valve packaging. For example, dualvalves may be used to independently control supply and exhaust lines for a single actuator, to implement basic logic functions in pneumatic circuits, or to route fluids through two separate channels without additional manifolds.

Advantages of dualvalves include reduced space, simplified manifolds, and potential cost savings from a consolidated control module. Limitations can include higher initial cost, increased maintenance complexity, and potential cross-talk between channels if not properly isolated and specified for the media and pressures involved.
