The ISO 5211 Valve Mounting Flange and Actuator Connection

Valve with ISO 5211 Flange

ISO 5211 is a European standard that specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.

A standard interface between actuator, valve, solenoids, and positioners  provides many benefits. Actuated valve assemblies are installed in a very wide range of applications and operating conditions resulting in many custom designs. Understanding the connection between these components is critical for long life, safety, and performance.

A standard mounting / connecting device lowers inventory costs and allows for faster maintenance and repair. Standardization also allows for the replacement of brands, so long as both adapt to the standard. Finally, using industry standard adapters maintain consistent specifications and tolerances which improve performance by reducing hysteresis and mechanical wear.

Kinetrol manufactures an ISO adapter for its models 02, 03, 05, 07, 08 and 09 which allows for mounting ISO 5211 valves directly to standard Kinetrol double acting actuators.
