Currently, two kinds of valves such as rotary type and button type are widely used in many applications. But, these valves have some problems that they are not controllable and reliable. Piezo actuation combined with modern microelectronics provides a reliable, quiet, low energy, infinitely adjustable gas valve. In this paper, gas valve using piezo actuator which are bimorph and a circle type was studied. Also, Prototype for gas valve was manufactured and characteristics of the prototype gas valve were analyzed. 한국세라믹학회 압전식 비례제어밸크 Proportional Flow Control Valve with PZT Actuator Article 2 한국세라믹학회지, v.42, no.11, pp.122 - 127 한국세라믹학회지 42 11 122 127 kci ART000974712 압전액추에이터 가스밸브 바이모프 액추에이터 비례제어 PZT actuator Gas valve Bimorph actuator Proportional control PZT actuator Gas valve Bimorph actuator Proportional control
