DESCRIPTION
A screw-in, cartridge-style, 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
• 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 size.
