EP08-35 Valve

EP08-35 Valve symbol

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

The EP08-35 is a spring-biased blocking valve which will shift to allow full flow from 1 to 2
only when pressure at 1 exceeds the cumulative pressure of 3, plus the bias spring pressure value.
EP08-35 is a pilot-to-close directional valve. With no pressure at 3, flow will be allowed from 1 to 2
once the bias spring force is overcome with pressure at 1.

• Compatible with diesel fuel types 1 and 2.
• Corrosion-resistant plating.
• Stainless steel option - consult factory.
• Multiple function/application potential.
• Low pressure drop.
• Compact size.
• Industry-common cavity.
