Optimized, Scalable, Flexible Technology
The unique multi-function characteristics of the piezo valve series means that just one valve can be used for isolation and regulation – which with conventional valves would require several different devices. Piezo valves offer precise control in a relatively small package, making them ideal for a wide range of high-performance situations. For example, some of the most important applications of piezoelectric valve actuators include aerospace equipment, precision instrumentation and medical technology.
With Marotta’s advanced piezo valve actuator technology, you can control flow parameters in real time and adjust the orifice size to meet your desired flow and pressure. The responsive piezoelectric actuator and integrated pressure transducers deliver state-of-the-art proportional control in a compact and lightweight package.
