Businesses today sample process liquids in process piping systems for a variety of reasons, including to:

  • Assess the quality of the process being measured (metrics typically measured include purity, temperature, color, density and clarity)
  • Refine or verify the process procedures
  • Capture a true, clean, representative sample
  • Provide operator safety and limit operator exposure
  • Reduces fugitive emissions

Process sampling has been done for many years, but only within the last decade have valve manufacturers designed improved process systems to the point where they are able to meet increasingly sophisticated sampling requirements.

Advancements made to today's modern sampling devices are due to requirements of the Occupational Safety and Health Administration

(OSHA) and the Environmental Protection Agency (EPA), as well as in response to increasing plant efficiencies and environmental and worker safety concerns.

As you consider which sampling method best meets your specific sampling requirements - ask yourself the following:

  • Why is the media being sampled?
  • What type of media is being sampled? (i.e. liquid, powder, slurry)
  • What are the properties of the media? (i.e. corrosive, hazardous, flammable, carcinogenic)
  • Where in the process is the sample being taken?
  • How often are samples taken?
  • What is the viscosity of the media? Are solids present?
  • Does the media crystallize?
  • Will the sample be taken from a pipeline or a vessel?

The following list describes different handle options NIBCO Sure Seal Sampling Valves have to make your next project a success. Don't forget to check the NIBCO blog often for more upcoming posts on why you should choose NIBCO Sure Seal Sampling Valves!
