7、PRACTICE SP-102 FOREWORD This MSS Standard Practice is based, in part, on IS0 International Standard 5210, Multi-turn Valve Actuator Attachment. It also reflects the common practice of the valve and valve actuator industries in North America today. Therefore, the ratings, sizes, and/or number of fla
8、nge types in the MSS Standard Practice for the North American market may differ from those of ISO. The MSS flange types use the IS0 designation, with the addition of an “A”, to distinguish them as American product. When assembling an actuator to a valve, a user is concerned with performance and mech
9、anical interface. In regards to performance, he needs in part: Adequate output torque for valve breakaway and seating loads, and for dynamic loads at rated flow. A specified speed so closing and opening can be accomplished in a prescribed time. Sufficient power rating of the actuator so the valve ma
10、y be cycled as required. Input power requirements. For mechanical interface, he is concerned in part with: The dimensional mating of the actuators mounting surface to the “valve” mounting flange. The dimensional compatibility of the actuators driving components to the valve stem. 0 Size and location
11、 of electrical and/or pressure connections. 0 Sufficient-space and capability to install and service the actuator This Standard Practice will only concern itself with flange and driving component dimensions and performance characteristics. 11 MSS STANDARD PRACTICE SP-102 CONTENTS SECTION PAGE 1 .

14、2. O 3. MULTI-TURN VALVE ACTUATOR ATTACHMENT FLANGE AND DRIVING COMPONENT DIMENSIONS AND PERFORMANCE CHARACTERISTICS SCOPE This standard practice is intended to provide a basis for the standardization of multi-turn actua- tor mounting dimensions and performance characteristics necessary for their at
15、tachment to general purpose industrial valves. It covers only those actuators supplied by manufacturers as separate components. 4.

16、ats. IS0 5210-1977, Multi-turn Valve Actuator Attachment. DEFINITIONS 5. Actuator: Any device designed for attachment to general purpose industrial valves in order to provide for the operation of the valve. Motive energy to the actuator can be electrical, pneu- matic, manual, etc., or a combination
17、of these. The movement is limited by travel, torque, thrust, or a combination of these. Multi-Turn Actuator: An actuator which trans- mits a torque to the valve for at least one revolution. Torque: A turning moment transmitted through the mounting flanges and driving components, 6. expressed in Poun
18、ds Foot or Newton Metres. Thrust: An axial force transmitted through the mounting flanges and driving components, ex- pressed in Pounds or Kilonewtons. FLANGE SIZE DESIGNATION Flange sizes are designated by the letters “FA”. The next two digits in the classification represent the bolt circle diamete
19、r, expressed in millimetres, appropriately rounded and divided by ten. As an example, a flange designated “FA30” represents: A) One intended for the American market. B) One with a bolt circle diameter (BCD) (D3) of approximately 300mm (exactly 298.5mm or 11.75 in.). ACTUATORIVALVE INTERFACE REQUIREM
20、ENTS When mating an actuator with a valve flange, the primary features of concern are the bolt pattern, type of bolt, the pilot, the performance (both thrust and torque), and driving component dimensions. Care must be taken in defining the driving components as there are numerous configurations. FLA
