COMPONENT GUIDE

Metal valve seat ring

Fixed seat of a specified metal-seated valve

Provides the drawing-defined stationary metal sealing interface.

Manufacturing & delivery form
Ring blank or suitable bar/tube stock followed by machining.

A metal ring is not a substitute for PTFE or elastomer seating without an approved design change.

Material candidates

UNS C95400 Aluminium bronze

A candidate for specified wear, guidance or structural components.

Candidate for drawing review only. Confirm load, counterface, lubrication and condition; it is distinct from C95800. Zhiren availability is unconfirmed.

UNS C95800 Nickel aluminium bronze

A candidate for specified saline-water and wear components.

Candidate for drawing review only. Review water chemistry, flow, mating metals and casting condition; no corrosion or cavitation guarantee. Zhiren availability is unconfirmed.

UNS C90500 Tin bronze

A candidate for drawing-specified pump, valve and friction components.

Candidate for drawing review only. Confirm medium, loading, manufacturing condition and the governing standard. Zhiren availability is unconfirmed.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.

Component RFQ requirements

Seat geometry: Inside/outside diameters, seating angle, width and retention.
Sealing pair: Mating disc material, hardness, contact profile, finish and lapping allowance.
Valve duty: Medium, pressure, temperature, cycling and assembled-valve leakage criteria.
Material specification: Alloy grade, governing standard and revision, manufacturing condition and any restricted substances.
Order & acceptance: Approved drawing revision, quantity, blank or machined delivery, inspection criteria and required records.

Start with your drawing, specified alloy and quantity. Include the required delivery condition and acceptance records so the manufacturing and inspection scope can be reviewed.
