CV08-20 Valve

SYMBOL:
CV08-20 Valve symbol

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

OPERATION
The CV08-20 allows 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.

FEATURES
• 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.
• Compact size.
• Fast closing and seating.
