Limitorque SMB 4T and 5T actuators incorporate a captured yoke bushing in the valve assembly to accept the high thrust loads of the application. We specialize in manufacturing the complete assembly, including all finished machining for internal ACME threads and external splines. Since we fabricate these assemblies in-house, we can deliver complete yoke assemblies in days compared to current 26-week lead times of valve manufacturers.

Durable Construction for the Toughest Applications
According to Flowserve, the SMB series actuators were the first actuators to be tested and approved for nuclear reactor containment, and also have proven reliability in fields such as oil and gas, hydroelectric, steelworks, pulp and paper, and wastewater management.
