By Michael D. Shaw When chemists and chemical engineers hear about “scientific” polling and surveys, they often wonder how quantitative the results can be, given that there is no control on respondents lying.
Sample stream selection assemblies must address contamination, deadlegs, and system size concerns as well as issues involving maintenance and performance to ensure efficient analytical system operation.
Valve technology will continue to evolve as opportunities emerge to upgrade systems to improve efficiency, reliability and safety.

Company offers a heavy-duty industrial inflatable seal ball segment valve that will not gum up, leak, pinch or damage product even in the most severe applications.
Offering high stability and excellent flow characteristics, the Electrically Actuated Ball Valve
These check valves prevent backflow in steam and water lines to protect valuable equipment from damage. They are used in extraction lines from steam turbines to feedwater heaters, heating systems or process equipment.
MIGHTY MINI SERIES stainless steel right angle valves feature a small footprint and a high cycle life bellows assembly of stainless steel construction for corrosion resistance. These valves are offered in manual and pneumatic actuation styles. Pneumatic valves are spring loaded fail safe.
C60 Series regulating valves are available in stainless steel, nickel alloy or solid brass and accommodate 0.75 to 1.25 NPT/BSPT plumbing. They provide flow from 0 to 40 gpm and can handle pressures from 75 to 2500 psi, with fluid temperatures up to 200°F.
Norgren has extended it VM valve island family to include the VM15. With a flow to size rate of 1.0 Cv, the 15mm-wide VM15 allows customers to specify a cost-effective compact valve island solution.
