The Maxseal / Thompson SOV3 Solenoid Valve is a high-performance, direct-acting valve engineered for robust flow control in harsh industrial environments. Designed to operate within a 0–20 bar pressure range, the SOV3 provides fast, repeatable actuation for air, inert gases, and compatible fluids.

This model features an ICO4D Ex-rated solenoid housing, ensuring safe operation in hazardous or explosive-risk zones. The 110 VDC coil provides strong magnetic force for positive valve engagement, enabling dependable performance under vibration, contamination, and fluctuating supply conditions.

With a 20 mm nominal diameter, the SOV3 supports medium-flow service ideal for shutdown systems, pneumatic actuation circuits, control panels, and wellhead applications. Its size 3 housing provides additional mechanical robustness and improved thermal dissipation.

Widely used in oil & gas, chemical processing, and utility automation, Maxseal solenoid valves are known for long service life and minimal maintenance requirements.
