Dynaquip Controls
Dynaquip Controls 145750.04 1/4 in 12 V DC solenoid valve 78.4 cfm 37-150 psi NEMA 4/4X
A 1/4 in solenoid valve operating at 12 V DC with 78.4 cfm flow and 37-150 psi pressure range in a NEMA 4/4X enclosure
- 12 V DC operation for low-voltage system integration
- 4 cfm flow capacity supports high-demand pneumatic circuits
- 37 to 150 psi pressure range suits varied industrial applications
- NEMA 4 and 4X enclosure resists water and corrosion
- 3 W power draw minimises electrical load
Application fit
This 1/4-inch solenoid valve operates on 12 V DC and delivers 78.4 cfm across a 37 to 150 psi range. It suits pneumatic automation, air-compressor control or vacuum-pump circuits that require a 4-way, 2-position, body-ported valve with NEMA 4/4X enclosure protection. Buyers who need larger port sizes, higher flow or different voltage ratings cannot use this model.
Installation notes
The valve mounts via 1/4-inch NPT ports and draws 3 W from a 12 V DC supply. A pilot pressure of 24.6 psi is required for actuation, so the supply line must meet that threshold. Wiring is straightforward with two coil leads, but reversing polarity or applying voltage outside the 12 V spec will prevent operation. Ensure the ambient temperature stays between 14 and 122 degrees F to avoid coil damage.
Interface limits
The 1/4-inch NPT connections and 1.4 Cv coefficient restrict maximum flow to the rated 78.4 cfm; systems demanding higher throughput need a larger valve. NEMA 4/4X rating protects against splashing water and dust but not prolonged submersion. The 37 psi minimum operating pressure means low-pressure circuits below that level will not shift the spool reliably.

Questions about this item
How can I confirm the valve is actuating correctly after wiring the 12 V DC coil?
Apply 12 V DC and listen for the solenoid click; verify airflow through the 1/4 in NPT ports at 78.4 cfm within the 37 to 150 psi operating range.
What comes in the box and what fittings or tubing must I supply separately?
The valve body with 1/4 in NPT ports is included; you must provide 1/4 in NPT fittings, tubing rated for 150 psi, and a 12 V DC power source.
Which configuration matches a 4-way, 2-position, spring-return valve with NEMA 4/4X rating?
This model 145750.04 is a 4-way/2-position solenoid/spring return valve rated NEMA 4 and 4X for 12 V DC operation.
