Certain industrial environments are harsher than others, and not all valves can take the heat. For example, the pulp and paper industry utilizes processes called batch steam cooks. The processes involve very hot steam, tough chemicals, and a high level of repetition- not ideal for just any valve. Pulp is one of the most abundant raw materials in the world and the United States is the second biggest supplier of paper across the globe. That means there are many mills in need of durable, reliable equipment. Some mills have also started producing pulp for the textile industry, another huge global market that requires mass quantities of material.
