20、ed by Information Handling ServicesPage 3 EN 60534-6-22001 INDUSTRIAL-PROCESS CONTROL VALVES - Part 6-2: Mounting details for attachment of positioners to control valves - Positioner mounting on rotary actuators 1 Scope This part of IEC 60534 is intended to permit a variety of positioning devices, w
21、hich respond to a rotary motion, to be mounted on the actuator of a control valve, either directly or by employing an intermediate mounting bracket. This standard is applicable where interchangeability between actuators and positioners is desired. a) The standardized mounting in this standard define
22、s the interface between the positioner and a part of the actuator having a rotary movement proportional to the control valve travel. 0 b) This standard also covers the direct connection between the positioner feedback and the shaft (or its axial extension) of a rotary control valve. In such cases, t
23、he feedback rotation is coincident with the valve angular travel. c) The standardized mounting applies to those rotary actuators in which the rotary part mentioned in item a) has a maximum travel of 90“. Such a travel is coincident with the valve travel when a direct connection (see item b) is perfo
24、rmed. d) The standardized mounting is divided into two options. Figure 1 shows the basic design and defines the minimum requirements an actuator must fulfil to adapt most common positioners. The universal design in figure 2 offers more variations of positioner adaptation and positioner feedback conn
25、ection. The positioner manufacturer should state which mounting design is required. 2 Definitions For the purpose of this part of IEC 60534, the definitions given in other parts of IEC 60534 apply. 3 positioner mounting 3.1 To allow the attachment of the positioner, the actuator manufacturer shall p
26、rovide a drilled plane surface perpendicular to the axis of the end of the rotary part mentioned in item a) of clause 1 and located at the distance indicated in figure 1 or 2, as appropriate. 3.2 The multiple drilling allows for different dimensions and masses of the positioner housing. 3.3 The posi
27、tioner may be mounted directly on the actuator, or indirectly by means of an intermediate bracket. The bracket on which the positioner is mounted may be an integral part of the actuator housing. 3.4 The mounting design shall take vibration resistance into consideration.

29、ll provide appropriate means for connecting the moving parts of the positioner to the shaft or shaft extension. The design of such linkage shall minimize the lost motion along the feedback path. 4.3 To allow for the possibility that the rotary part is rigidly connected to the valve shaft, thermal li
30、near expansion of the rotary part of up to 1 mm shall be taken into account by the positioner manufacturer. 4.4 The feedback connection shall take vibration resistance into consideration. 5 Mounting accessories Unless otherwise specified, the positioner manufacturer shall provide two or more M6 scre
31、ws (plus nuts and washers) according to the design of the positioner, to permit the positioner mounting on the actuator.
