Piston valve liquid samplers

Sampling of liquid by piston type valves

To take samples the conventional way is not only inefficient, but in the case of dangerous media, humans and the environment are subjected to high safety risks, the Mechatest piston valve liquid samplers are the safe and efficient solution for storage tank sampling. 

The Mechatest piston valves are a perfect solution for liquid sampling from tanks, containers, pipeline, reactors and mixers, to take representative samples of liquids with higher viscosity by using a piston valve, the entire line diameter can be cleared by the return of the piston. Sample dosing and filling of the sample bottle is made possible and regulated with a crank or hand wheel, in contrast to a ball valve.

The big advantage of piston type valve sampling is the direct into the wall mounting principle, the sample is directly take of the inside tank, container, pipeline, reactors or mixer. We have improved our sampling systems for liquids by:

  • Creating closed loop systems which provide a safe, controlled environment
  • Adding sample (needle or process) purge options
  • Fixed volume sampling, which minimizes both waste and costs
  • Simplifying designs, making the sampling of liquid and gas more efficient
  • Proper discharge of excess liquid or gas prevents unwanted pressure build-up in the system

These modern solutions simply regard the sampling systems themselves. Our worldwide reputation rests on the combination of excellent systems, and professional services by our team of specialists.
