What Is a 24V Solenoid Valve
A 24V solenoid valve is an electromechanically actuated valve driven by a 24 V DC coil, the industrial default for PLC-controlled pneumatic and fluid systems. Carroland Pneumatics supplies 24V solenoid valves for compressed air, inert gas, and low-viscosity liquid service, built to ISO 15552 and IS15867 dimensional standards and manufactured under a Foxconn-certified production system in place since 1992. The 24 V DC coil is noise-immune, safe, and directly compatible with the vast majority of industrial controllers.
Why 24 V DC Is the Industrial Standard
24 V DC coils draw 7–12 W and respond in under 25 ms. They resist electrical noise better than 12 V, support longer cable runs, and match the standard output of virtually all automation PLCs. For most fixed machinery this is the recommended coil voltage.

- Cooling and rinsing circuits with low-pressure liquid
Frequently Asked Questions
Can I run a 24V solenoid valve on 12V?
No. A 24 V DC coil requires its rated voltage to develop full force; 12 V will leave the valve sluggish or non-actuating. Use a 12 V DC coil for low-voltage systems or supply a regulated 24 V.
Does a 24V solenoid valve work with water?
Yes, when specified with a water-compatible seal (EPDM or FKM) and the correct port thread. Carroland 24V solenoid valves are offered for air, inert gas, and low-viscosity liquid duty.
What is the response time of a 24V solenoid valve?
Under 25 ms at rated voltage, suitable for high-cycle automation including clamping, blow-off, and dispensing.
Which port sizes are available?
Standard threads run from G1/8 to G1/2, with manifold bodies on ISO 15552 dimensions for common pneumatic mounting.
Are Carroland 24V solenoid valves dimensionally standard?
Yes. Bodies follow ISO 15552 and IS15867 interface dimensions so they fit standard manifolds and pneumatic patterns used across automation.
