CV04-(B)20 Valve

CV04-(B)20 Valve symbol

A screw-in, cartridge-style, pressure regulator for use in diesel engine applications, such as
variable flow pumps, fuel and oil controls, and SCR/EGR emission and exhaust controls. Available
in conventional surface mount or convenient “down-hole” versions.

The CV04-20 and CV04-B20 allow flow passage from 1 to 2, while normally blocking oil flow in
the opposite direction. The cartridge has a fully guided check which is spring-biased closed until
sufficient pressure is applied at 1 to open to 2.

• Compatible with diesel fuel types 1 and 2.
• Corrosion-resistant plating.
• Stainless steel options available - consult factory.
• Hardened seat for long life and low leakage.
• Optional bias springs for back-pressure application flexibility.
• Fully guided check assembly.
• Miniature size.
• Fast closing and seating.
