Valves

Valves serve five primary functions in a fluid system. which are:

  • On/off: starts or stops flow within a system,
  • Flow control: regulates flow,
  • Directional flow: determines the direction of flow,
  • Over-pressure protection: safely relieves system pressure if a pressure spike occurs and
  • Excess flow protection: shuts off or restricts flow to prevent an uncontrolled release of a process fluid.

When selecting a valve for an instrumentation system, your choices may seem overwhelming. Just to name a few, there are ball valves, diaphragm and bellows valves, as well as check valves, excess flow valves, fine metering, gate, multi-port, needle, plug, relief, rising plug, and safety valves. Furthermore, each of these valves comes in many sizes, configurations, materials of construction, and actuation modes. To make the best choice, it is always good practice to ask the first question in valve selection: What do I want the valve to do?
