What Is a 12V Solenoid Valve
A 12V solenoid valve is a low-voltage electromechanically actuated valve driven by a 12 V DC coil. Carroland Pneumatics supplies 12V 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 12 V DC coil suits battery-backed panels, mobile equipment, and low-voltage control circuits where a 24 V supply is unavailable.
Why Choose 12 V DC
12 V DC coils draw 6–8 W and respond in under 25 ms. They are intrinsically safer for portable and vehicle-mounted systems and pair directly with 12 V PLC or relay outputs without a step-up converter. For fixed industrial machinery, 24 V DC remains the more common standard.

Frequently Asked Questions
Is a 12V solenoid valve compatible with a 24V supply?
No. A 12 V DC coil must be driven at its rated voltage; applying 24 V will overheat and destroy the coil. Use a 24 V DC coil if your controller output is 24 V, or regulate the supply down to 12 V.
Can a 12V solenoid valve run on water?
Yes, when ordered with a water-grade seal (EPDM or FKM) and the correct port thread. Carroland 12V solenoid valves are offered for air, inert gas, and low-viscosity liquid duty.
What port sizes are available for 12V solenoid valves?
Standard port threads range from G1/8 to G1/2, with manifold-mount bodies following ISO 15552 dimensions so they fit common pneumatic interfaces.
How fast does a 12V solenoid valve switch?
Response is typically under 25 ms at rated voltage, supporting high-cycle automation such as clamping, blow-off, and dispensing.
Are Carroland 12V solenoid valves dimensionally standard?
Yes. Bodies follow ISO 15552 and IS15867 interface dimensions so they mount on standard manifolds and pneumatic patterns.
