The global piezoelectric proportional valve market was valued at US$ 651.6 Mn in 2016 and is projected to register a CAGR of 5.5% from 2017 to 2026. The 0–2.0 bar type segment in the global piezoelectric proportional valve market is estimated to account for major revenue share of 43.6% in 2017 owing to factors such as high availability, less energy consumption, and high efficiency and performance levels when compared to conventional/solenoid proportional valves.
Piezoelectricity or piezoelectric effect refers to generating electric charge as a result of mechanical stress, vibrations, or heat. Piezoelectric effect has one unique characteristic of reversible effect. That is, when stress is applied it generates electricity, and when electric field is applied, it generates stress.
Piezoelectric proportional valves can be a better alternative to conventional solenoid valves as they offer more benefits than that of conventional valves, especially in applications requiring directly controlled proportional valves.
Piezoelectric proportional valves are small, lightweight, durable, fast, and save energy. In addition, Piezo valves make minimal noise, generate very little heat, and are highly accurate, which makes them ideal for application in healthcare devices.However, high voltage requirement and high cost of piezoelectric valves may hamper growth of the piezoelectric valve market to a certain extent.
