The Microvalve Bundle contains: two units of Normally closed microvalve - negative pressure,  two units of PEEK Male Luer fluidic adapters or PEEK tube connectors and one unit of programmable ECU (ECU-P2-nc) control module.  Inside the normally-closed valve, a shape memory alloy actuator switches the valve open by pressing a spring element to the top. A small ball closes the opening of the valve. By pressing the spring element to the top, the ball is released from the opening allowing fluid to flow through the valve.
