Schneider Electric MK-4601 Globe Valve Pneumatic Actuator

Globe Valve Pneumatic Actuator, the Schneider Electric MK-4601, delivers precise valve control with rugged reliability. This linear, spring-return actuator is designed for upright mounting with the actuator head above the horizontal center line.

Constructed with a rugged die-cast aluminum body, it features a 1/2 inch stroke, 1/8 inch female threaded air connections, and a 30 PSIG pressure rating. The diaphragm is neoprene with an 11 square inch working area, providing consistent response across a wide ambient temperature range (-20 to 220°F). The device supports 2-position (On/Off) proportional control and carries a NEMA 1 protection rating for basic indoor environments.

Ideal for precise control of globe valves in HVAC, water, or process systems.
