DESCRIPTION
A screw-in, cartridge-style, spool-type, spring-biased, pressure-reducing
logic element.

OPERATION
The ER10-S30 acts as the pressure-reducing element when used in conjunction with a pilot
relief valve connected to port 3. The outlet - port 1 - is connected to the spring chamber and
port 3 through the orifice in the spool. When the pilot relief valve is closed, the pressure-reducing
element is completely open and allows oil to flow from the inlet at port 2 to the outlet at port 1 with
minimum pressure drop. On attainment of a pre-determined pressure at port 1, the spool shifts to
increase pressure drop between 2 and 1, thereby reducing and maintaining pressure at port 1 equal
to the preset pilot pressure at port 3.

FEATURES
• Spring-biased, spool type logic element
• For use in conjunction with a pilot relief valve
• Hardened spool and cage for long life.
• Corrosion-resistant plating option available.
• Industry-common size.
