Frequently Asked Questions

Question 1

Which industrial valve families does SMD Valves manufacture?

Accepted Answer

SMD Valves’s published range includes ball, gate, globe, check, butterfly and plug valves, together with strainers and configured flow-control solutions. Exact construction, size, pressure class and material availability should be confirmed against the selected product and RFQ.

Question 2

How should we select a valve for a project?

Accepted Answer

Start with the medium, pressure, temperature, size, pressure class, end connection, operating frequency, shutoff or control duty, actuation and applicable standards. SMD Valves can then review the proposed construction and identify information still required.

Question 3

Which body and trim materials can be considered?

Accepted Answer

Published SMD Valves information covers cast and forged carbon steels, stainless steels, duplex grades, cast and ductile iron, and selected nickel alloys such as Monel, Inconel and Hastelloy. Suitability depends on the service condition and purchase specification.

Question 4

Which standards can SMD Valves manufacture against?

Accepted Answer

SMD Valves publishes products around relevant API, ASTM, ANSI, AWWA, JIS, DIN, BS and ISO requirements. The applicable edition, product scope and project deviations must be stated in the RFQ and confirmed for the specific valve.

Question 5

How do we verify certificates and approvals?

Accepted Answer

Request the current certificate copy, scope page, issuing body and validity information before supplier approval or order award. A certificate name on a website is not a substitute for validating the current document and product scope.

Question 6

Can SMD Valves manufacture from our data sheet or drawing?

Accepted Answer

Yes, configured manufacturing can begin from a customer data sheet, drawing, sample or approved requirement set. SMD Valves should confirm construction, materials, interfaces, marking, inspection points, document index and any deviations before production.

Question 7

What private-label elements can be configured?

Accepted Answer

Depending on the agreed program, private-label scope can include nameplates, body marking, color, packaging, labels and document templates. Approval files and traceability rules should be agreed before release.

Question 8

Which inspection and testing activities are available?

Accepted Answer

Typical capability includes incoming-material review, dimensional inspection, PMI when specified, PT, MT or UT when applicable, pressure and leakage testing, marking checks and final release. The exact route is defined by the product standard and approved ITP.

Question 9

Can customers or third parties witness tests?

Accepted Answer

Witness and hold points can be incorporated when agreed before production. The RFQ should state the nominated inspector, required stage, notice period, acceptance criteria and signed release record.

Question 10

What can be included in the manufacturing record package?

Accepted Answer

Depending on scope, the package can include approved drawings, material certificates, traceability records, dimensional reports, NDT reports, pressure-test reports, marking records and final release documents. Define the required index before production.

Question 11

What information is needed for an accurate quotation?

Accepted Answer

Provide valve type, size, class, quantity, medium, pressure, temperature, materials, end connection, actuation, standards, inspection points, documentation, marking, packing and delivery requirements. Attach data sheets or drawings where available.

Question 12

What is the typical lead time?

Accepted Answer

Lead time depends on valve construction, size, pressure class, material availability, quantity, inspection points, third-party witness and document scope. SMD Valves should confirm the production schedule against the final technical and commercial requirement set.

Question 13

Which contact details should be used?

Accepted Answer

Use info@smdvalves.com or the RFQ form on this website. The published factory address is No. 112, Dayuan Street, Shuige Industrial Zone, Lishui City, Zhejiang, China 323000.
