The EP-311/313 incorporates a quiet low-wattage poppet valve and
pressure sensor to measure and adjust the branch line pressure
proportional to the input. This unit has no air consumption and is
immune to mounting orientation or supply line pressure fluctuations.
The EP-313 incorporates a manual override switch and, in the manual
mode, the pressure can be increased or decreased with two pushbutton
switches. This feature is most desirable for check out/commissioning
and manual operation in case of controller failure. Universal 24
VAC/24 VDC supply voltage and field selectable 4-20mA, 0-5 VDC, or
0-10 VDC inputs ensures single unit compatibility to most of the
systems. Unique steel chassis design substantially reduces the
overall size of the unit and, at the same time, provides for ease of
installation in a control panel directly or with a snap track. A
precision gauge is provided for the branch line pressure. Rugged
aluminium manifold, brass barb fittings, floating poppet solenoid
valves, silicon pressure sensor, high performance electronics and a
liberal two year warranty are some of the features which make the
EP-311/313 the highest performance and the most reliable
electropneumatic transducer in the industry.
