Save energy and enhance flexibility with Parker’s latest electro-pneumatic pressure regulators (Oct 2010)

26 October, 2010

Parker Hannifin has launched its latest range of remote controlled electro-pneumatic pressure regulators to provide flexibility, precision and energy savings in a wide range of manufacturing applications. The new EPP4 Comfort models have been designed to enhance the performance and reliability of machinery within the production environment, including welding, paper and printing and machine tool robots, as well as on trucks and trains for the control of adaptive suspensions.

Featuring a compact and lightweight construction, the new 1” and 2” EPP4 Comfort models have been specifically developed for quick and easy installation and low inertia on moving robots. Using an integrated electronic control system and pulse width modulated solenoid valves, the units control the output pressure proportionally to an analogue electrical signal, while high precision is achieved by an internal feedback through an integral pressure sensor. As a result, control systems can be simplified dramatically through the reduced number of components, while productivity is improved through the greater degree of flexibility.
Fast response
The EPP4 Comfort range is said to offer extremely fast response times, excellent linearity and low hysteresis of 0.5 per cent for the accurate and fast adjustment of the controlled pressure, significantly increasing production efficiency. Power consumption is said to be notably low, requiring a maximum only 6W, enabling simple integration into standard installations, and as no air is used when there is no change of control signal, energy and cost savings can be achieved still further.
The flexible and easily mounted  EPP4 Comfort regulators feature plug and play functions to provide simple tools for setups and monitoring using standard PC software, which enables the user to set all the relevant parameters of the units quickly and simply, both on and off site. Additionally, the remote display enables users to read the regulated pressure wherever the application requires it and the large, high clarity LED digits make reading faster and easier. The EPP4 Comfort 1” & 2” pressure regulators are available for control by either a voltage or current analogue control signal, offering either analogue or digital outputs, and are adjustable to meet the specific parameters of each application.
