ER12-S30 Valve

SYMBOL:
ER10-S30 Valve symbol

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

OPERATION
In its steady state, the ER12-S30 allows flow from 2 to 1 with the spring chamber
constantly drained at 3. On attainment of a pre-determined pressure at 1, set by a
(remote) pilot relief valve connected to port 3, the spool shifts to restrict input flow at 2,
thereby regulating pressure at 1.

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