Poppet Valve Technology

DESCRIPTION

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 ecient, 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.

APPLICATIONS

● Hospitals

● Schools

● Pneumatic dampers/actuators

EP3

FEATURES

● Field-selectable 4-20mA/0-5V/0-10VDC input for application exibility

● Poppet valve technology for quiet operation

● Manual override with set and hold feature...great for commissioning

those leaky systems

● Multi-point calibration; 3-15 psi (5 point calibration) and 0-20 psi

(6 point calibration)

● Pressure loss alarm provides a contact closure if the EP3 is unable to

achieve the desired output within a xed length of time

● Failsafe vent solenoids bleed branch pressure on power failure for added safety

● Optional transparent plastic dust cover (AA43) protects units from dust

and tampering (required for CE)

● User programmable zero and full scale outputs

● Backlit LCD for local indication of readings...easy to view

● Dual-color LED...assists in trouble shooting

● Tristate and PWM inputs
