Valve Classification Based On Operation

Types of Valves

Valves can be classified by:
  • Multi-turn valve (linear motion valves): The closure member has a linear displacement generally by turning its threaded stem several times. This operation is slow, but it gives accuracy and stability to position the closure member, which is necessary in some control valves.
  • Quarter-turn valve (rotary valve): The closure member as well its shaft turn 0º-90º; from the fully-open position to the fullyclosed position. They are quick opening/closure valves.
