RV10-21F Valve

SYMBOL:
RV10-21F Valve symbol

DESCRIPTION
A screw-in, cartridge-style, direct-acting, spool-type, pressure regulator intended
for use as a pressure limiting device for diesel engine applications, including variable
flow pump, fuel and oil controls, SCR/EGR emission and exhaust controls.

OPERATION
The RV10-21F blocks flow from 1 to 2 until sufficient pressure is present at 1 to force
the poppet off its seat. The cartridge offers fast response to load changes in typical
hydraulic circuits requiring low internal leakage.

FEATURES
• Compatible with diesel fuel types 1 and 2.
• Corrosion-resistant plating.
• Stainless steel options available - consult factory.
• Several pressure codes available.
• Rapid response to pressure surges.
• Low internal leakage.
• Industry common cavity.
• Hardened spool and cage for long life.
