EP10-S35 Valve

SYMBOL:
EP10-S35 Valve symbol

DESCRIPTION
A spool-type, screw-in, cartridge-style, pilot-to-close directional element, with
multi-function potential when used with other directional, pressure, or flow control
devices. Can be used as a pressure regulator for diesel engine applications including
variable flow pump controls, fuel and oil controls, SCR/EGR and exhaust controls
and transmission controls.

OPERATION
The EP10-S35 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.
EP10-35 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.

FEATURES
• Compatible with diesel fuel types 1 and 2.
• Corrosion-resistant plating.
• Stainless steel option - consult factory.
• Multiple function/application potential.
• Low pressure drop.
• Range of bias spring pressure options. Tall cap required for 160, M11, 230, and
   M15.9 spring options.
• Industry-common cavity.
