Valvelor

Valvelor is a term used in fluid power and microfluidics to denote a compact, integrated valve-actuator assembly that controls the flow and pressure of a fluid within a system. A valvelor typically consists of a cartridge housing multiple microvalves or proportional valves, a shared fluid plenum, and an assembly of actuators (solenoids or piezoelectric elements) with integrated sensing and control electronics.

Operation hinges on coordinating valve states to direct fluid paths, regulate pressure, and sequence operations. Because valves are integrated with actuation and control in a single package, a valvelor can implement complex valve networks with fast response and reduced external hardware.

Construction and variants: Valvelors are designed as modular units, available in single-valve and multi-channel formats. Materials include stainless steel, brass, and engineered polymers. Actuation methods include electromagnetic and piezoelectric drivers; control can be analog or digitized via digital interfaces or fieldbuses.

Applications and advantages: They are used in robotics, industrial automation, aerospace, lab instrumentation, and microfluidic devices, enabling compact, reliable fluid control. Benefits include smaller footprint, reduced tubing, faster switching, and easier system integration. Limitations include higher cost, greater design complexity, and potential thermal management considerations.

History and terminology: The term valvelor is not tied to a single manufacturer and has been used in engineering literature since the late 20th century to describe integrated valve-actuator packages; it may be marketed under various product names.
