Integrated Valve, Actuator Control Solves Pneumatic System Problems

Oct. 24, 2012
Reduced energy consumption, simpler installation and maintenance, and easy washdown are the key advancements of a new integrated valve and actuator control (IVAC) cylinder from Norgren Inc., Littleton, Colo.

Working within the same footprint as a standard actuator, the company developed a modular motion control unit that combines the cylinder, pilot and control valves, position sensors and speed regulators in a single integrated unit.

“By eliminating the tubing and remote valve islands typical of pneumatic operations, the IVAC reduces the energy costs of compressed air by up to 50 percent, while delivering faster response times,” said Richard Bull. “Eliminating tubing also saves space, improves aesthetics and simplifies cleaning.”

Norgren takes these advantages a step further in the cleanline IVAC. With the switches and valve inside a smooth casing, the cleanline version of the IVAC had an ingress protection rating of IP 67, making it attractive for operations like food or beverage handling where frequent washdowns are required.

The IVAC can be used as a retrofit or installed in existing designs with no mechanical changes. With just one electrical and one pneumatic connection, the IVAC is installed quickly and simply.

“The IVAC helps OEMs design equipment that is more compact, efficient and attractive, while helping end users save energy and improve hygiene,” said Bull. See the unit’s design innovations and unique features in action online, at
