Requesting a Quote for Gate Valves
A gate-valve quotation is an isolation-duty quotation: size, pressure class, wedge and seat construction, stem arrangement and body material decide the offer. The parameters below are what a quotation-ready inquiry states up front.

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 body and trim materials and any corrosion or NACE requirement. |
| Pressure and class | Pressure class fixes the pressure boundary and the bonnet design range. |
| Temperature | Body and trim materials track the service temperature span. |
| Size | Nominal size fixes the flow path, weight class and face-to-face. |
| Wedge and seat construction | Wedge type and seat materials decide the sealing behaviour for the duty. |
| Connection | Flanged, butt-weld or threaded ends must match the pipework standard. |
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 88" (DN15 to DN2200), depending on model | Face-to-face constraint or space envelope for replacement in place |
| Pressure class | PN10 to PN450, Class 150 to Class 2500 | Class or PN rating beyond the published span |
| Materials | Cast iron, Ductile iron, WCB, WCC, LCB, LCC, WC6, WC9, CF8, CF8M | Trim materials, NACE service or exotic bodies for corrosive media |
| End connections | Flanged, Butt-weld, Socket-weld, Threaded, Wafer, Lug | Flange standard and facing to mate the pipework specification |
| Wedge and seat | Stainless steel, hardfaced metal, cobalt-chromium hardfacing alloy, resilient seating | Solid wedge, flexible wedge or split wedge; seat overlay requirements |
| Stem options | Rising stem, Non-rising stem | Rising or non-rising stem; headroom above the handwheel at the installation |
| Bonnet designs | Bolted bonnet, Welded bonnet, Pressure seal | Bolted, welded or pressure-seal bonnet per the line class |
| Design standards | API 600, API 602, API 6D, ASME B16.34, DIN 3352 (F4/F5), BS 5163 | Testing standards and market certification marks the project requires |
Drawings and documentation
What to attach to the inquiry — and what to ask for back with the order confirmation.
Line specification excerpt
Size, rating, body and trim materials, end connection and bonnet design.
Operating conditions
Media, temperature and the isolation duty — gate valves are open-or-closed valves, not throttling valves.
Stem and operation preference
Rising or non-rising stem; manual, gear or actuated operation and any headroom limit.
Applicable standard reference
The design and testing standards the valve must carry for the project.
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 gate-valve quote?
Size, pressure class, body and trim materials, wedge and seat construction, stem arrangement, bonnet design, end connection, media and temperature. An inquiry carrying these moves directly to quotation.
Can the gate valve be quoted for throttling duty?
Gate valves suit isolation duty where the valve stays open or closed for long periods rather than throttling. If your line needs regulation, state the duty in the inquiry and the quote proposes the globe or control-valve family that fits it.
How are lead time and MOQ handled?
Lead time and minimum order quantity depend on size, class, materials and bonnet design 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.
