ESS12

Double solenoid, 2-position, no springs. Spool shifts and remains shifted when one solenoid or the other is momentarily or continuously energized. Standard models are assembled for "Internal Pilot" operation. This operator style will operate reliably on line pressures from 150 PSI down to 25 PSI. If the line pressure is 150 PSI to 250 PSI or less than 25 PSI to 28" Hg, then the solenoid operator must be configured to use an "External Pilot" source. Pressure: 25 to 150 psi on the main body of the valve when solenoid is internally piloted.
Vacuum: The valve cannot be vacuum operated when the solenoid is internally piloted.
Temperature: -20?F to 120?F ambient. Caution: If it is possible that the ambient temperature may fall below freezing, the medium must be moisture free to prevent internal damage or unpredictable behavior.
Mounting: The spool is friction positioned so the valve must be mounted with the spool in a horizontal orientation.
O-Rings: Buna-N in main valve, Viton in control valve.
Solenoid Seat: Viton.
Materials: 356-T6 aluminum body aluminum body, hard anodized aluminum spool, A380 aluminum end caps, Viton solenoid seat, composite gaskets, steel fasteners.
Flow: 1627 SCFM, 37.8 Cv
Repair Kits: ERKV-16 & ERKV-3.
3-Way or 5-Way: This valve is basically 4-way, it must be configured for external pilot (Option 'Z') for 5-way service by using ports 2 or 4 as an inlet, or 3-way service by plugging the unused port 2 or 4.
Fluid Media: Soft seal models are made for air, vacuum, and gases compatible with component materials. They should not be used with liquids.
