The EP2 Series combines a microcontroller with high performance low power coil, poppet valve technology to create a system with unparalleled accuracy and proven reliability. The poppet valves used in the EP2 Series consume no air, eliminating unnecessary air losses in the system and allowing for efficient, long-term operation. The EP2 Series permits versatility, since all models feature manual override. The LCD provides easy visibility and the LED indicators provide visual status of valve operation in manual or automatic mode. All models come with SnapTrack housing and optional covers are available.
