Dual Solenoid Operation: Minimum coil on-time for dual solenoid valves is 0.3
seconds on air service and 1.0 seconds on liquids.
Caution: Do not energize both solenoids simultaneously.
Refer to Engineering Section for details.
Standard Voltages: 24, 120, 240, 480 volts AC, 60 Hz (or 110, 220 volts AC, 50 Hz).
6, 12, 24, 120, 240 volts DC. Must be specified when ordering.
Other voltages are available when required.

Refer to Engineering Section for details.
Approvals
CSA certified. Meets applicable CE directives.
Important
A Minimum Operating Pressure Differential must be
maintained between the pressure and exhaust ports.
Supply and exhaust piping must be full area, unrestricted.
ASCO flow controls and other similar components must
be installed in the cylinder lines only.
• Loss of air pressure may allow valve to shift on dual
solenoid constructions.
Standard: Watertight, Types 1, 2, 3, 3S, 4, and 4X.
Optional: Explosionproof and Watertight, Types 3, 3S, 4, 4X, 6, 6P, 7, and 9.
(To order, add prefix “EF” to the catalog number.)

25 psi (1.7 bar) minimum on light oil service. For best results, do not use valve rated 250 psi (17 bar) on mainline pressure of less than 125 psi (9 bar).
On 50 hertz service, the watt rating for the 6.1/F solenoid is 8.1 watts. Water rating, CSA certified up to 232 psi.
