What’s Happening With Pumps and Valves
May 3, 2005 7:55 am | Medical Design Technology | Product Releases | CommentsFigure 1. New peristaltic pump roller designs with a convex roller and concave tubing bed allow pumping media containing live cells with much less damage to the cells. The tube is squeezed in the middle first while the edges remain open, so the cells escape shearing or crushing.

Gas Metering Valve
July 8, 2004 11:39 am | South Bend Controls, Inc. | Product Releases | CommentsThe gas metering valve is a direct-acting proportional SERVOID® valve driver provides linear proportional control of the metering orifice which yields linear proportional flow. This valve features a suspended-armature design that is inherently reliable and results in very low hysteresis.

December 4, 2003 7:07 am | South Bend Controls, Inc. | Product Releases | CommentsThe proportional solenoid valve is a single-stage direct-acting proportional solenoid valve. The valve provides a flow rate which is linearly proportional to the input current. The maximum air flow capacity is 120 SLPM with an inlet pressure of 25 psig and approximately 5 watts power requirement.
