To suit most process conditions and designs, we offer three types of sample valves in many configurations with numerous options:

Type Description Pros Cons
In-line Sample Valve Fitted directly on the process line or on a bypass. A constant flow through the valve guarantees a directly representative sample.
  • Directly representative sample
  • Liquid/gas flow required (re-circulation loop, process line)
Lateral Sample Valve The valve is fitted on the side or bottom of a reactor or on the side of a larger pipeline.
  • Bypass not required for large pipes
  • Reactor sampling without re-circulation loop
  • Dead space needs to be purged or flushed to guarantee a representative sample.
Top of Reactor Sample System Acts as a re-circulation loop.
  • Works under pressure as well as under vacuum
  • Directly representative sample
  • Max viscosity = 2,000 Cp

The first step in selecting a BIAR Sample Valve is to identify where it will be fitted on the process line. After you make that determination, you can outline technical specifications such as sampling temperature/pressure, size, class and product properties. Those specifications normally correspond to the Piping & Instrumentation Diagram (P&ID).
