A lot of process control manufacturing operations are at risk of hazardous
accidents. Safety regulations are continually instituted and monitored by
the Occupational Safety and Health Administration (OSHA) to ensure
compliance.
Additionally, ISO 9000 certification is another set of standards that valve
companies comply with to manufacture and test their products. Likewise,
major end users have their own standards for the valves they use in their
process control operations, which are called Approved Manufacturers Lists
(AML).
