A dependable butterfly valve supply programme begins with the operating conditions, not a generic catalogue number. Greysen reviews medium, pressure, temperature, size, flange standard, shut-off duty and actuation before confirming the configuration.
Application review
The same nominal valve can require a different seat, disc, coating or operator when the fluid, temperature or differential pressure changes.
Manufacturing control
Body and disc preparation, machining interfaces, stem alignment, seat fit and coating are controlled against the approved specification.
Testing and documentation
Shell and seat tests, dimensional inspection, marking and project documents are agreed before shipment.
Project communication
Distributors and contractors receive a clear technical quotation, drawings where required and confirmation of deviations before production.
Information to include with an enquiry
Provide nominal size, pressure rating, medium, temperature, connection standard, materials, operating method, required testing and project documentation. Greysen will review the duty and confirm the final configuration in the approved data sheet.
