RV10-21F Valve

RV10-21F Valve symbol

A screw-in, cartridge-style, direct-acting spool-type valve intended for use as a
pressure regulating device for diesel engine applications, including variable flow
pump controls, fuel and oil controls. This stainless steel model is ideal for use in
SCR/EGR emission and exhaust control applications.

The RV08S-21F allows pressurized fluid to pass from port 1 (inlet) to port 2 (outlet),
while normally blocking fluid in the opposite direction.
The cartridge has a fully guided spool 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.
• Precise cracking pressure.
• Repeatable reseat.
• High cycle life.
• Custom pressure ranges available for application flexibility.
• Compact size.
• Precise, repeatable reseat characteristics.
