A direct mounting flange according to ISO 5211 is standard for this segment ball valve.
This feature allows an actuator to be mounted without the need for a mounting bracket and drive adapter. This results in a significant cost reduction, a compact automated unit, and a higher level of safety for operators.
The ISO regular-mounting pad accepts direct mounting of pneumatic and electric actuators.
ISO 5211 is a European standard that specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.
