Schneider Electric MK-2690 Globe Valve Pneumatic Actuator

The Schneider Electric MK-2690 Globe Valve Pneumatic Actuator is engineered for reliable, precise valve control. This globe valve pneumatic actuator delivers linear motion with a spring-return design, optimized for upright mounting in demanding industrial environments.

Constructed with a rugged die-cast aluminum body, it fits compactly at 5" W x 2-1/4" D x 3-9/16" H and offers a 1/2" stroke. It operates from a 30 PSIG air supply through a 1/8" female thread, and uses a neoprene diaphragm with a 6 in2 effective area to provide fast, repeatable actuation across a wide temperature range (-20 to 220°F) and 5–95% humidity (non-condensing). The unit supports a 2-position On/Off proportional control, making it suitable for precise valve positioning and automation sequences, while maintaining NEMA 1 protection for basic indoor use. The actuator is designed for multiple spring ranges to adapt to system pressure: Yellow 3–7 PSIG, Black 5–10 PSIG, Blue 8–13 PSIG.
