DESCRIPTION
A screw-in, cartridge-style, pressure regulator for use as a pressure-regulating
device in common diesel engine applications, such as variable flow pump controls,
fuel and oil controls and SCR/EGR emission and exhaust controls.

The CV94-20 allows flow from port 1 (inlet) to 2 (outlet), while normally blocking flow
in the opposite direction.The regulator is spring-biased closed until sufficient pressure
is applied at 1 to open to 2.
