ER10-S30 Pressure Reducing Spool Logic Element (ER10-S30)

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

 

Product Operation

In its steady state, the ER10-S30 allows flow from ➁ to ➀ with the spring chamber constantly drained at ➂. On attainment of a pre-determined pressure at ➀, set by a (remote) pilot relief valve connected to port ➂, the spool shifts to restrict input flow at ➁, thereby regulating pressure at ➀

Product Features

 Adjustments cannot be backed out of the valve.
 Adjustments prohibit springs from going solid.
 Optional spring ranges to 207 bar (3000 psi).
 Hardened spool and cage for long life.
 Industry common cavity.
