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).
