of valves, plus full engineering support from application engineering and
detailed specifications to design and inspection.
Quality assurance is recognized as a management function, administered by
engineering and quality assurance departments which operate independently
of the manufacturing and sales functions, thus ensuring the authority and
integrity of their activities.
Quality control is implemented through a comprehensive system of works instructions
using a quality manual written to reflect requirements. Quality plans, drawings
and quality procedures control all activities from order review through to
final testing and delivery to ensure special customer requirements are achieved.
