Valves are essential components in many industrial processes because they control the flow of fluids or gases. They are used in a wide range of industries, including oil and gas, chemical, pharmaceuticals, and water treatment. Valves must operate consistently, reliably, and safely over long periods of time. Any defects or failures in valve performance can have major consequences, such as leaks, equipment damage, or safety hazards. Therefore, valve manufacturers must implement careful quality control measures to ensure that their products meet the highest standards of safety, reliability, and durability.
