Model EV-----------------------------------------------------------------------------RWD E4#67

   Model PEV----------------------------------UL, ULC, IAS, RWD E4#67(for PEV-1, -2,-3)

MODEL  EV&PEV  Series are two-stage regulators/converters. They are intended for vapor withdrawal systems. Heating with engine coolant is not required. Diagnostic test ports are standard for both the primary and secondary pressure chambers, and a choice of diaphragm materials is available. EV&PEV Series regulator/converters are renewable with the appropriate repair kits

The EV Series regulator is used primarily on propane fuel systems that require a negative pressure but do nor require fuel vaporization. The EV is only available with the standard “B” (blue)spring. It is possible, however, to convert the unit to use with the optional “O” (orange) spring.

The PEV Series regulator is designed for positive-type CNG fuel systems where liquid vaporization is not require. Specific PEV regulators are available in several outlet pressure Adjustable pressure units are also available. Fixed regulators can be converted in the field to adjustable with the AC174 kit. Adjustable units can be converted to fixed outlet pressure by using the appropriate 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 deterent to unauthorized tampering)
