1 Scope
This document provides requirements for metallic mounting kits for part-turn valves and actuator attachments.
It includes all components transmitting torques from actuators to valves with a maximum
flange torque up to 16 000 Nm (up to F30 flange type).
It applies to mounting kits for part-turn valves and actuators with integral attachment flanges and drive components
as described in ISO 5211 (see Figure 1), when direct mounting of the actuator on valve is not practical. Figure 1 illustrates the two different types of mounting kits in the scope of this document.

Mounting kit between part-turn actuator and valve
Key
| 1 | part-turn actuator | 5 | gearbox |
| 2 | interface (see ISO 5211) | 6 | interface (see ISO 5210) |
| 3 | valve | 7 | multi-turn actuator |
| 4 | mounting kit |
 |
 |
| a) Direct interface with mounting kit | b) Direct interface with mounting kit (when combination of a multi-turn actuator and a gearbox) |
Stacking of mounting kits/intermediate supports is not within the scope of this document.
This document specifies methods for design and environmental corrosion protection.
When a reference is made to this document, all the requirements apply, unless otherwise
agreed between the purchaser and the manufacturer/supplier, prior to order.
In this document, the term "valve" covers valve or shaft extension top-flange, and
the term “actuator” covers part-turn actuator or combination of multi-turn actuator and gearbox.
Control valves are excluded from this document.
