01 / COMPONENT REQUIREMENTS

Butterfly valve disc

Identify the required geometry, material and acceptance criteria for your drawing-based casting enquiry. Illustrations and material options are not a stock catalogue or a statement of approved supply scope.

Generated part illustration, not a Zhiren product photograph or an engineering drawing. Final geometry follows your controlled drawing.

CASTING COMPONENT

Butterfly valve disc

Butterfly-valve flow passage

Rotates about the valve shaft to control flow. Disc edge geometry must match the specified resilient or metal seating design.

Material options

UNS C95800Nickel-aluminium bronze

An option for seawater-wetted castings where corrosion resistance and strength are important. Casting condition, water quality and flow conditions require review.

Select the grade against the drawing, duty conditions and applicable material standard. These candidates are not interchangeable and do not establish confirmed manufacturing scope.

Information for your quotation

Disc geometry: Diameter, thickness, profile, shaft bore and flow orientation.
Shaft & seat: Shaft connection, bush locations, seat type, disc-edge finish and required tolerances.
Design duty: Medium, pressure, temperature, rotation direction and valve test requirements.
Material specification: Alloy designation, governing standard, casting condition and any restricted substances.
Order & acceptance: Drawing revision, quantity, delivery condition, critical tolerances and required inspection records.

Custom casting enquiries are welcome to your drawing, specified alloy grade and applicable material standard. Manufacturing scope is confirmed during quotation.
