IMPCO Model EV & PEV are two-stage regulators .Specific PEV
regulators are available in several fixed outlet pressures
DESCRIPTION
The Model EV & PEV are two-stage regulators for vapor fuel
applications where vaporization is not required. Diagnostic test
ports are standard for both the primary and secondary pressure
chambers, and a choice of diaphragm materials are available. The EV
comes with the standard “B” blue secondary spring with -1.5” w.c.
and an optional “O” orange secondary spring is also available with
a give up pressure of -0.5” w.c.
Specific PEV regulators are available in several fixed outlet
pressures. Adjustable pressure units are also available. Fixed
regulators can be converted in the field to adjustable, with the
AC1-74 kit.
Adjustable units can be converted to fixed outlet pressure by using
the H3-3 spring cover. This is preferred for applications that are
not subject to fuel quality variations, or for those where
emissions are a concern (the spring cover acts as a deterrent to
unauthorized tampering).
