CE Certification High Pressure Globe Valve Manufacturers & Factories

To satisfy CE compliance under the European Pressure Equipment Directive (PED 2014/68/EU), high-pressure globe valves intended for Category III and IV fluid groups must undergo comprehensive conformity assessment (typically Module H - Full Quality Assurance). This entails certified material traceability (EN 10204 Type 3.1 minimum), rigorous finite element stress analysis (FEA) validating ASME B16.34/EN 12516 shell calculations, non-destructive testing (PT, MT, RT) on cast and forged pressure boundaries, and verified hydrostatic shell (1.5x PN) and seat (1.1x PN) testing witnessed and signed off according to EN 12266-1 standards.

While gate valves are strictly designed for on/off isolation with minimal pressure drops, they suffer rapid galling and disc vibration when exposed to throttling. High-pressure globe valves are engineered specifically for precise regulation and severe differential pressure drops. The disk travels perpendicular to the seat ring, eliminating sliding friction across seating faces. In high-pressure steam drains, boiler bypass, and continuous modulating applications, globe valves offer significantly higher service life, simpler in-line re-facing, and reduced mechanical maintenance.

For temperatures exceeding 400°C (752°F), all resilient elastomer materials decompose. We mandate hardfaced solid cobalt-chromium alloys, primarily HF Stellite Grade 6 (overlayed with plasma transferred arc welding) on both the disc cone and integral body seat ring. This achieves a minimum surface hardness of 40-45 HRC, preventing thermal degradation, galling under high-pressure seating loads, and erosive damage caused by microscopic liquid droplets in wet steam cycles.

Yes. Beyond producing standard ASME B16.10, DIN EN 558, and BS 2080 face-to-face configurations, our in-house engineering and CNC center can tailor end-to-end dimensions, extended weld necks, or RTJ flange profiles to match existing legacy piping envelopes precisely, reducing field modification and hot-work welding costs during plant turnaround turnarounds.

Every shipment includes an exhaustive QA/QC Dossier consisting of: Material Test Reports (MTR) according to EN 10204 3.1, Hydrostatic Shell & Seat Leakage Test Certificates, Dimensional Inspection Reports, Wall Thickness Inspection Records, Positive Material Identification (PMI) logs, and CE Certificates of Conformity. Additional third-party inspection (SGS, TÜV, Bureau Veritas) can be facilitated upon request prior to factory dispatch.
