Dynaquip Controls 145855.03 Solenoid Valve 1/4 in 24V DC 78.4 cfm
A 1/4-inch solenoid valve operating on 24V DC delivers 78.4 cfm at 22 to 116 psi with NEMA 4/4X rating
- Precise 24 V DC actuation for reliable automation
- 4 cfm flow capacity supports demanding pneumatic circuits
- 22–116 psi operating range handles varied pressure needs
- NEMA 4/4X rating protects against dust and water ingress
- Low 3 W power draw reduces energy consumption
Solenoid Air Control Valve
This Dynaquip Controls 145855.03 solenoid valve is a 4-way, 2-position air control component designed for pneumatic automation. It operates on 24V DC with a solenoid and spring return actuator. The body-ported design features a 1/4 inch pipe size and NEMA 4, 4X enclosure rating for industrial environments.
Upgrade from manual or 3-way valves
This valve replaces manual levers or simpler 3-way valves when automated directional control of double-acting cylinders is required. The jump is worth it when a system needs reliable electrical switching with a 3 W power draw and a 17.4 psi pilot pressure. It suits applications moving up to 78.4 cfm within a 22 to 116 psi operational range.
Limits of 1/4 inch porting and NEMA 4 rating
The 1/4 inch NPT ports and 1.4 Cv coefficient restrict maximum flow to 78.4 cfm, limiting use to smaller actuators or lower-demand circuits. Ambient temperature must stay between 23 and 140 degrees F. The NEMA 4, 4X rating protects against washdown and corrosion but does not certify the valve for hazardous locations.

Questions about this item
What size NPT thread does the 1/4 in pilot port on the Dynaquip 145855.03 require?
The pilot port uses a 1/4 in NPT thread, so fittings must match that taper and diameter for a leak-free seal.
Which step is often missed when wiring the 24 V DC coil on this valve?
Installers frequently forget to confirm polarity on the DC coil; reversing the leads will prevent the solenoid from actuating.
What operating pressure range should be monitored to know when seals on the 145855.03 need replacement?
The valve is rated for 22 to 116 psi; if system pressure drifts outside this range or leakage appears, the internal seals are likely worn.
