The chemical industry is a big user of valves of all types and materials. From small batch plants to the huge petrochemical complexes found on the Gulf Coast, valves are a huge part of chemical process piping systems.

Most applications in chemical processes are lower in pressure than many refining processes and power generation. The most popular pressure classes for chemical plant valves and piping are Classes 150 and 300. Chemical plants have also been the biggest driver of the market share takeover that ball valves have wrestled from linear valves over the past 40 years. The resilient-seated ball valve, with its zero-leakage shutoff, is a perfect fit for many chemical plant applications. The compact size of the ball valve is a popular feature as well.
