Product Overview
The EP3 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 EP3 consume
no air, eliminating unnecessary air losses in the system and allowing for efficient, long-term operation. The EP3
permits versatility, since all models feature manual override and a tri-state control option. 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
