BSI BS 5793-6:1986

Industrial-process control valves -- Specificaton for mounting details for attachment of positioners to control valve actuators

PUBLISH DATE 1986
BSI BS 5793-6:1986

This standard is intended to permit a variety of positioning devices which respond to a linear motion to be mounted on the actuator of a control valve, either directly or by employing an intermediate mounting bracket. There is a large variety of types, sizes and designs of actuators. The following parameters define the intended applicability of this standard for the guidance of manufacturers and users.

  1. The standardized mounting applies only to positioners which are mounted on the side of the actuator.
  2. The standardized mounting applies in general only to those actuators which have a travel of 100 mm or less.
  3. The standardized mounting is designed to cover three basic types of actuator design (see Figure 1, page 12):
    1. those with some form of cast or fabricated yoke to connect the actuator power unit to the valve;
    2. those which use some form of central tube yoke to connect the actuator power unit to the valve;
    3. those in which the yoke incorporates two or more columns or pillars to connect the actuator power unit to the valve.
Methods of mounting a variety of positioning devices on the actuator of a control valve, either directly, or by employing an intermediate mounting bracket. Thus compatibility of products from different manufacturers will be assured.
