RUGGED
CONSTRUCTION
Inlet components are made of metal to withstand full supply
pressure. Moulded PVC housings endure rough handling as well
as resist corrosion.
POSITIVE
INDICATION OF OPERATION STATUS
A unique lever mechanism and front panel knob provide the operator
with a quick indication of 3 or 4 operation modes (operating,
low gas supply, off, and standby for automatic switchover arrangements).
An additional built-in red indicator becomes visible in the
low/out-of-gas situation and an optional contact is available
for remote indication.

SECONDARY
PRESSURE CHECK
The 500PPD regulator has a unique, built-in additional check
valve, designed to confine gas under pressure should dirt build
up on the primary valve seat.
LOCAL
OR REMOTE VENT VALVE
The pressure relief vent is built into the regulator housing
to keep all vent lines in the gas supply room. If desired, the
vent can be relocated away from the regulator to satisfy specific
application requirments. |
