Requesting a Quote for Ball Valves
A ball-valve quotation turns on four selections — size, pressure class, bore and seat material versus temperature — plus the end connection that mates the line. The parameters below are what a quotation-ready inquiry states up front; the published ranges show the span each selection normally covers.

Required inquiry parameters
An inquiry that states these values is quotation-ready — selection can start without a second round of questions.
| Parameter | Why the quote needs it |
|---|---|
| Medium | Decides seat and seal materials and whether soft seats are permissible. |
| Temperature | Seat material choice and body rating track the operating temperature span. |
| Pressure | Pressure class and any high-differential condition fix the pressure-boundary rating. |
| Size | Nominal size and bore type (full or reduced) fix the flow path and face-to-face. |
| Connection | Flanged, butt-weld, socket-weld or threaded ends must match the pipework standard. |
| Operation | Manual, gear, pneumatic or electric — actuated valves need supply and fail-safe details. |
Standard ranges and custom options
Published reference ranges for this family, with the question to ask for each dimension when the requirement sits outside the span. Non-standard requirements are confirmed during quotation.
| Dimension | Published range | If non-standard, specify |
|---|---|---|
| Size | 1/2" to 48" | Full bore or reduced bore, and any face-to-face dimension constraint |
| Pressure class | ANSI Class 150 to Class 2500 | Differential pressure and cavitation or high-pressure drop conditions |
| Materials | WCB, WCC, CF8, CF8M, SS304, SS316, Duplex, Super Duplex, Alloy 20, nickel-molybdenum alloy, nickel-chromium alloy, Aluminium Bronze | Exotic alloys for corrosive media beyond the standard stainless and duplex set |
| End connections | Flanged, Butt Weld, Socket Weld, NPT | Flange standard and facing, or special weld-prep for butt-weld ends |
| Seat options | PTFE, RPTFE, PEEK, Metal Seated | Seat material versus temperature and media — soft seat limits at high temperature |
| Temperature range | -196°C to 650°C | Cryogenic or high-temperature execution beyond the published span |
| Operation | Manual, Gear Operated, Pneumatic, Electric | Actuation torque data, fail-safe position and control signal for automated valves |
| Design standards | API 6D, API 608, ASME B16.34 | Fire-safe, anti-static and blow-out-proof test certificates where the spec calls for them |
Drawings and documentation
What to attach to the inquiry — and what to ask for back with the order confirmation.
Line specification excerpt
Size, rating, end connection, body/seat/trim materials and any fire-safe or anti-static requirement.
Operating conditions
Media, temperature range, pressure and flow direction or double-block-and-bleed duty if required.
Actuation requirements
Pneumatic, electric or gear operation; supply voltage/air pressure and fail position for actuated valves.
Applicable standard reference
The design and testing standards the valve must carry for the project specification.
Documents to request with the order
General arrangement drawing, material certificates and test reports — availability confirmed with the quotation.
Lead time, MOQ and pricing
Supply terms are quoted per inquiry — size, class, materials and certification scope all move them, so they are confirmed rather than published as generic figures.

Frequently asked questions
What is the minimum information for a ball-valve quote?
Size, pressure class, bore type, body and seat materials, end connection, media and temperature, and operation type. An inquiry carrying these moves directly to quotation.
Can non-standard sizes, materials or pressure classes be quoted?
Requirements outside the published reference ranges are confirmed during quotation. Provide the line specification and operating conditions; the quote response states what is covered and how.
How are lead time and MOQ handled?
Lead time and minimum order quantity depend on size, class, materials and actuation scope and are provided per inquiry — contact for confirmation rather than relying on a generic figure.
Ordering & documentation
Documents
Ask for the documentation set with the inquiry — typical items (material certificates, test reports to the listed inspection standard, dimensional drawings) are confirmed and supplied with the quotation.
Quotation
Send the medium, temperature, pressure, size and connection for a quotation-ready inquiry. Lead time, MOQ and price are confirmed at quotation, together with the documents to be supplied with the order.
Sample & supply
Supply terms, order quantities and lead time are agreed per order — state the destination country and required schedule with the inquiry.
Storage & shipping
Store valves with seats and seals protected from UV, ozone and deformation, and keep end-face protectors on until installation; storage limits and shipping arrangements for the selected materials are confirmed at quotation.
