The valve is the crucial part of any sampling system. Based on the process conditions we will select the right valve for the application (both physically and chemically compatible).

A wide range of valves (both make and type) can be used in Dopak samplers, such as needle valves, instrumentation ball valves and process (in-line) valves. Many of the valves are able to meet the standards required (e.g. NACE, Tüv), and are available in threaded and/or flanged connections (ANSI, ASME, DIN).

Valve body material options may include:

• SS316 (Standard)
• M400 (Monel)
• HC276 (Hastelloy)
• I825 (Incoloy)
• I625 (Inconel)

Seat material options:

• Polytetrafluoroethylene (PTFE) (Standard)
• PEEK
