Standard, Intrinsically Safe and Explosion Proof
Single & Double Acting
The EP5 electropneumatic positioner is adapted from the PMV P5 pneumatic positioner. This compact and sturdy unit is designed for maximum performance in all types of environments. The EP5 is available in Standard, Intrinsically Safe and Explosion Proof versions. A modular feedback unit F5 allows for the addition of limit switches and/or position transmitters, without additional mounting brackets.
Other features include: Replaceable filter, gauge ports, dampers, tapped exhaust port for venting of supply media, external zero adjustment and completely sealed cover.
EP5 FAIL FREEZE
EP5 Fail Freeze offers enhanced system safety gained from it's fail freeze characterestic. In the event that the 4-20 mA input signal is lost, EP5 Fail Freeze will fail in place. The unit is loop powered and needs no additional power supply. It features a rugged design, high gain, high capacity gold plated spool valve, external zero adjustment, gauge ports, replaceable filter, tapped exhaust port, all in an IP65/NEMA 4 enclosure.
Additional capabilities include the direct mounting of a sealed feedback unit, F5, with the ability to include switches, position transmitter or a potentiometer. The F5 mounts on top of the EP5 Fail Freeze requiring no additional brackets or linkage.
PMV also offers a wide range of mounting kits, cams and accessories, to easily customize the EP5 Fail Freeze to fit your application.
