Four Valve Types Compared: Floating Ball, Trunnion Ball, Gate, Butterfly

Compare the four main valve types side by side across size, pressure class, body material, end connection and operation, covering the full DN50–DN1200 range. EPC and oil & gas buyers confirm the valve type and key parameters here before sending an RFQ, then have engineering verify the configuration.

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.
