COMPONENT GUIDE

Fire protection gate valve body

Sprinkler or standpipe control valve

Contains the pressure boundary and locates the gate, seat and end connections.

Manufacturing & delivery form
Valve-body casting with drawing-defined machining.

Obtain the exact body alloy from the approved fire-valve drawing; a bronze trade name does not establish C83600. Complete-valve listing is separate from casting supply.

Material candidates

UNS C83600 Leaded red brass

A candidate for specified cast valve bodies, covers and connection housings.

An application candidate, not a confirmed equipment bill of materials or available Zhiren grade. Do not default to potable-water use.

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

Approved design: Provide the OEM drawing revision, gate arrangement, orientation and required change-approval process.
Pressure boundary: Define wall sections, casting-defect acceptance, design conditions and body leak-test method and limits.
End connections: Specify exact thread/flange standards, dimensions, sealing faces and local interface requirements.
Gate and bonnet interfaces: Identify seat locations, guides, bonnet joint, datums and machining allowances.
Qualification records: State approved material standard, first-article and batch documents and the OEM's complete-product verification responsibility.

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.

COMPONENT GUIDE

Check valve body

Reverse-flow prevention point in a fire-water line or pump discharge

Houses the check-valve flow passage and supports the specified closure mechanism.

Manufacturing & delivery form
Pressure-containing body casting with agreed machining.

Closure and sealing materials may differ from the body. Opening behaviour and assembled-valve leakage require design and assembly validation.

Material candidates

UNS C83600 Leaded red brass

A candidate for specified cast valve bodies, covers and connection housings.

An application candidate, not a confirmed equipment bill of materials or available Zhiren grade. Do not default to potable-water use.

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

Valve configuration: Supply the approved swing/lift or other design, orientation, body geometry and flow direction.
Closure interfaces: Define hinge/pin or guide geometry, seat datum, cover joint and closure travel.
Pipe interfaces: Specify connection standard, end dimensions, seal faces and installation envelope.
Body acceptance: Provide pressure/temperature, wall and defect limits, leak-test criteria and inspection responsibility.
Approved release: Specify alloy, revision control, material/batch records and complete-valve test/qualification responsibility.

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.

COMPONENT GUIDE

Check valve disc / FDC clapper

Closure element inside a specified check valve or fire department connection

Moves about the drawing-defined hinge or guide to close against the mating seat.

Manufacturing & delivery form
Near-net casting with machining or another approved blank route.

Only assess copper-alloy closures specified by the OEM. A copper-alloy FDC body does not establish a copper-alloy clapper.

Material candidates

UNS C83600 Leaded red brass

A candidate for specified cast valve bodies, covers and connection housings.

An application candidate, not a confirmed equipment bill of materials or available Zhiren grade. Do not default to potable-water use.

UNS C90500 Tin bronze

A candidate for specified pump and valve components.

Review the actual medium, mating materials and manufacturing condition. Material data do not establish component pressure, wear life or pump performance.

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

Closure geometry: Provide disc profile, hinge lug or guide, mass-related design requirements and approved drawing.
Pivot and travel: Specify pin bore, retaining method, opening travel and installation orientation.
Seat interface: Define sealing profile, counterface material, any elastomer interface and surface finish.
Operating acceptance: Allocate impact/closing behaviour, pressure and assembled leakage validation to the specified responsible parties.
Material and traceability: State approved alloy, casting/blank route, machining state and first-article/batch 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.
