A phacoemulsification apparatus includes a phacoemulsification probe, an electromechanical valve, and an electromechanical mechanism. The probe having a fluid channel for exchanging fluid with a patient's eye. The electromechanical valve is coupled with the fluid channel and is configured to regulate a fluid flow through the fluid channel. The valve including a cylinder, a piston inside the cylinder, wherein the piston divides the cylinder into a first cavity that is in fluid communication with the fluid channel, and a second cavity, and one or more fluid communication links, which are formed between the first and second cavities. The piston is configured to move inside the cylinder to regulate the flow of the fluid, and the one or more fluid communication links are configured to allow the fluid to flow between the first and second cavities during motion of the piston. The electromechanical mechanism is configured to move the piston.
