Stainless Steel Globe and Gate Valves For Industrial Process Control

GettyImages-1686744392-1

Gate and globe valves see common usage throughout fluid processing industries. The correct procedure for valve selection includes an evaluation of the process media, environment, and how the valve will need to perform.

Gate valves, unless specially adapted, are intended for applications requiring only fully open or closed service. Their slow operation is advantageous in preventing hammering in the piping system and a fully open gate valve presents little pressure drop.

Globe valves are well suited for shutoff and throttling operation, controlling fluid flow at points between fully open or closed. The “Z” pattern of their fluid path does add some pressure drop.

Selecting the right valve construction material is an important element of a successful installation. Aloyco, a Crane brand, recommends consideration of several factors.

  • Type of media
  • Media temperature range
  • Pressure range, including all possible conditions
  • Environmental conditions which may affect the valve
  • Extraordinary stresses to which the valve may be subjected
  • Compliance with safety standards and/or piping codes
Stainless steel valve construction will provide an additional measure of corrosion resistance and maybe a selection that extends the useful life of a valve.
