The
EP-350 interfaces with up to four separate
EP-311/313 electropneumatic transducers to ensure
fail safe
bleed to zero pressure. The EP-350 solenoid
holds a transducer's bleed port closed until power
is lost and then
opens the port, which allows the branch
ports of all connected transducers to exhaust pressure
upon power failure.
The
EP-350 incorporates an aluminum block manifold
that is fitted with four ¼-inch brass hose
barbs and a single power solenoid. By connecting
transducers' branch lines to the EP-350's four
hose barbs,
pressure
ports are kept isolated from one another
to ensure that no pressure mixing occurs across
pneumatic
ports.
