Schneider Electric MK-2690-0-0-2 Relay Module

Schneider Electric MK-2690-0-0-2 is a pneumatic valve actuator designed for proportional control of 1/2" to 1-1/4" VB-series valves (notably VB-111 and VB-9xxx), enabling precise valve positioning in process and automation systems; this variant is the no-spring configuration, typically used when an external return mechanism is employed; when paired with the VB-7263-0-4-5 valve body it forms a compact actuation assembly for industrial control; Schneider’s AV-400 linkage kit is recommended for mounting and linkage to the valve body, with VK-series linkages available for specific VB combinations; the MK-2690 family is documented in Schneider Electric’s North America valve catalog (F-27855) alongside VB-7263-0-4-x valve bodies, confirming compatibility and variant options; commonly used in process control, water treatment, and HVAC systems that demand reliable pneumatic actuation of VB-series valves.
