Certifications and Market Access Documents

What Saudi and UAE project approvals really hinge on: whether the valves are manufactured to API 6D and API 607, whether the quality system is ISO 9001 certified, and whether the shipment can carry documents meeting Saudi SASO/SABER and UAE ESMA requirements.

API 6D Pipeline Valve Manufacturing and Inspection
Ball, gate and butterfly valves are designed and manufactured to API 6D, covering the common Class 150/300/600 and PN10–PN40 ratings in a full size range from DN50 to DN1200. Every valve is hydrostatically shell-tested and seat-tested before shipment, with test pressure and temperature per API 6D.
API 607 Fire Safety and Anti-Static
Trunnion-mounted ball valves and gate valves for oil, gas and petrochemical pipelines can be supplied with API 607 fire-safe and anti-static design: pressure-relief body construction, anti-static sealing elements and packing. This complements API 6D and is stated in the contract technical conditions.
ISO 9001 Quality Management System
Covers casting, machining, assembly and final inspection. Incoming material traceability, dimensional and material inspection records are archived by batch, supporting the document packages required for oil and gas pipeline projects.
PED 2014/68/EU Pressure Equipment Directive
Pressure-rated valves exported to the EU are classified under PED 2014/68/EU, covering pressure-retaining material certificates, welding procedure qualifications and pressure test reports. Applicability and classification must be confirmed against the contracted product and specification.
Saudi SASO / SABER Shipment Documents
For Saudi projects we can support the SABER certification process with conformity certificates, material certificates and test documents, and assist the client with product and batch certificate declarations. Declaration scope and validity are subject to review by the Saudi authorities.
UAE ESMA Documents and Customs Clearance Files
For UAE projects we can supply the clearance file with the shipment — conformity certificate, packing list, material and test reports — and support the client in completing registration under the ESMA system. The exact document list and format follow the client's current requirements.

Common market-entry requirements; applicability and documentation are subject to the destination country's current regulations and mutual confirmation.

Why Buyers Choose Us as Their Valve Supplier

This supplier gets selected on verifiable hard facts: casting and machining under one roof, shell and seat leak testing on every valve, heat-number traceability, bilingual technical documents, and quotations within 24 hours.

Casting and Machining Under One Roof

Casting, rough machining and finish machining are all done in the same plant, reducing outsourced steps and dimensional variation.

100% Shell and Seat Leak Testing

Every valve is shell and seat leak tested at low and high pressure per API 6D, with a report issued for each test.

Heat Number Traceability Throughout

Heat numbers follow the valve body through production, with A105, F316 and duplex material certificates available.

Full Range DN50–DN1200

Full size range from DN50 to DN1200, available in Class 150/300/600 and PN ratings.

Quotation Within 24 Hours

Questions Buyers Ask Before Ordering

What is the MOQ? Can different sizes be mixed in one order?

For standard models, 5 units per size and pressure rating minimum; different sizes can be mixed in the same order. Trunnion-mounted ball valves and actuator-equipped valves start at 10 units.

How fast is the quotation, and what selection data do you need?

Quotations are returned within 24 hours. Please provide valve type, size (DN50–DN1200), pressure class (Class 150/300/600), material and connection end, and we will price accordingly.

What is the lead time? Do actuator valves take longer?

Standard ball, gate and butterfly valves ship in 25–35 days; trunnion ball valves and electric or pneumatic actuator packages take 40–50 days, subject to the confirmed order.

Can third-party inspection (SGS, BV) be arranged?

Yes. Before inspection we provide drawings, material certificates and welding procedure documentation; the inspection is carried out item by item against API 6D, and the report is shipped with the goods.

Which certifications and shipping documents are needed for Middle East exports?

Valves are supplied to API 6D; Saudi Arabia requires SASO/SABER and the UAE requires ESMA documents, all based on the certificate originals you provide. The shipment includes the packing list, invoice, certificate of origin and hydrostatic test report.

What are the payment terms and warranty?

30% deposit with 70% against a copy of the bill of lading. Warranty is 18 months; spare seals, seats and bolts can be ordered separately and arrive by air freight in about 7 days.
