Norgren IVAC integrated pneumatic actuators

Norgren has launched a high-performance range of cylinders, designed to significantly reduce energy usage and operating costs for OEMs and end users in a range of processing applications.

Conventional pneumatic control involves an arrangement of valves or valve islands, actuators, flow controls and sensors, along with connectors and accessories. In typical applications, up to 13 different components can be required for each actuator function. This complexity presents some intrinsic disadvantages and performance constraints. Norgren has developed IVAC (integrated valve and actuator control) - an integrated unit which combines the valve, flow controls, cushioning and sensors in a single actuator package.

IVAC is a weight- and space-optimised actuator, suitable for a range of bore sizes from 40 to 80 mm, featuring an integrated valve and magnetically operated switches for complete actuator control. Able to be retrofitted or integrated within new systems, each unit requires only one pneumatic and one electrical connection, eliminating the need for multiple valve islands, components, tubing and accessories.

A number of options and varieties are available including cleanline versions for industrial cylinders, industrial slave cylinders and easy washdown, helping OEMs comply more easily and cost effectively with hygiene regulations.

The design of the integrated actuator is based on modularity to allow all components to be easily assembled and disassembled. The IVAC’s modular concept includes a special pilot module which is placed directly at the end of the actuator barrel, and the integration of a pneumatic interface, position sensing, display for status and electrical connection.
