Application of shape memory alloy with all-round effect to flow control values

A b str a c t. This paper describes a new approach to a flow control valve using SMA plates with the all-round shape memory effect (ARSME). As the temperature becomes higher than the transformation temperature, fluid can automatically flow because of the shape change of the plates. The relationship between temperature and flow rate were investigated experi­ mentally. Temperature rises were caused by electromagnetic inductive heating.
