CMT (ceramic multilayer actuator) technology is able to give response times as low as 100 sec, a practically unlimited service life and very low power consumption of 0.007W, which is the reason Asco Joucomatic has chosen it for its new piezo electric solenoid valves.
The new valves incorporate a CMA element with a monolithic piezo-ceramic strip with integrated electrodes that are configured so that the element bends when a voltage is applied. The bending action is used to open or close one or more nozzles in a valve, or to govern proportionally the flow of air to a pneumatic system.
The unique operation of the piezo valves means that there are no inductive peaks when switching, so no circuit protection is necessary. No holding current is required for the valves to maintain position so heat generation is not a problem either.
