description
AT70 series electro-hydraulic actuator is a new generation of intelligent heavy hammer self-protecting piezoelectric liquid actuator developed by our company. It is widely used in water industry applications requiring two-stage quick opening or two-stage quick closing, for example: power plant The emergency relief valve of the indirect air cooling device and the two-stage slow closing butterfly valve after the circulating water pump adopt the latest CPU intelligent control technology and the advanced variable diameter cylinder principle to ensure that the water hammer effect does not occur. Long-term reliable operation.
