Lucifer Fluid Connectors

Parker Lucifer is the leading ATEX valve manufacturer in the world, they offer one of the widest product ranges in this market are constantly finding new, simpler and safer solutions.


EPP4 Comfort proportional pressure


The Legris range of EPP4 Comfort proportional pressure regulators offers a wide range of advantages over competitor products. All perameters for them for example, can be adjusted through the easy to use Calys PC software, reducing set up time and therefore cost. Their long life expectancy makes them even more cost effective, and when you couple that with the low maintenence requirement, it's easy to see what gives Legris products the edge over competition.


The regulators themselves are compact and light, constructed of a full aluminium body. The piston is fabricated in a special polyacetal and is equipped with high performance dynamic seals, specially developed by Parker Lucifer for this application. The technology used is fully digital. The cancellation of potentiometers allows customers to realise an easy, safe and precise set up in their production.
