Direct answer: Gaoshan Valve passed its annual PED 2014/68/EU Module H surveillance audit on September 10–11, 2026, with auditors from an EU Notified Body on site. Under Module H, full-quality-assurance surveillance is required every year to keep the CE certificate valid for pressure-bearing valves shipped into the European Union market.
For European EPC contractors, plant operators, and industrial buyers, a current Module H certificate is the difference between a valve that can be legally installed under the Pressure Equipment Directive and one that will be rejected at customs or by the end user.

What PED 2014/68/EU Module H Actually Requires
Module H is a “full quality assurance” conformity assessment route under the EU Pressure Equipment Directive. It means the Notified Body does not only test a single sample — it audits the manufacturer’s entire quality system that produces CE-marked pressure equipment.
For Gaoshan Valve’s pressure-bearing valve line, the September 2026 audit covered:
- Design control and technical file maintenance
- Welding procedure qualifications (WPS / WPQR) and welder qualification certificates
- Non-destructive testing (NDT) procedures and records
- Material certificate traceability per EN 10204 (3.1 / 3.2)
- In-process production records
- Final pressure testing per EN 12266-1 / -2
The audit was not a paperwork exercise. Auditors physically reviewed welds, test rigs, material traceability files, and the production line itself.
Why Annual Surveillance Matters for European Buyers
PED 2014/68/EU is enforced by EU member-state market surveillance authorities. Pressure equipment without a valid CE certificate and Declaration of Conformity cannot be:
- Placed on the EU market
- Put into service in PED Category I, II, III, or IV installations
- Accepted by most EPC contractors and end users as compliant supply
A Module H certificate is typically valid for three years, with annual Notified Body surveillance audits in between. If a manufacturer skips or fails a surveillance audit, the certificate is suspended and the CE mark can no longer be affixed to new production. This is the regulatory mechanism that protects European buyers from unverified, low-quality pressure equipment.
The Audit’s Six Verification Areas
1. Design Control
Auditors reviewed the technical files for representative valve models — pressure-containing body design, bonnet-to-body joint, stem sealing, and disc/seat geometry. They confirmed that design changes since the last audit had been properly documented and re-validated against the harmonized standards referenced in the technical file.
2. Welding and Welder Qualification
Gaoshan Valve’s WPS (Welding Procedure Specification) and WPQR (Welding Procedure Qualification Record) files were checked against EN ISO 15614-1. Welder certificates were verified for currency and scope coverage on the alloys actually used in production.
3. Non-Destructive Testing (NDT)
Radiographic, ultrasonic, and magnetic-particle testing procedures for cast and forged valve bodies were reviewed. The auditor spot-checked recent NDT reports against acceptance criteria in EN 12223 (visual examination of castings) and EN 12680 (radiographic testing of castings) as applicable.
4. Material Traceability
Each pressure-bearing component is traceable to its material certificate per EN 10204 — 3.1 certificates for standard supply, 3.2 for higher PED categories. Auditors verified heat-number mapping from incoming raw material through finished valve on selected production orders.
5. Production Records
The auditors reviewed the production travelers for selected orders — checking that the planned WPS, NDT, and pressure-test steps were actually performed, signed off, and traceable to qualified personnel.
Document review session: technical files, welding records, and production travelers cross-checked against the approved PED Module H quality system.
6. Final Pressure Testing
Hydrostatic shell and seat tests were witnessed and re-validated against EN 12266-1 / -2 leakage classes. Industrial service typically requires Class A minimum; many Gaoshan Valve lines are supplied to Class B or higher on request.
Witnessed final pressure test: auditors recorded gauge readings on the hydrostatic test bench as objective evidence for the audit file.
What This Means for Your Project
When a European EPC or industrial buyer sources pressure-bearing valves from a Chinese manufacturer, the PED Module H certificate and current surveillance audit record are non-negotiable. They typically need to:
- See the CE certificate and the issuing Notified Body’s four-digit number
- Confirm the certificate is in its valid window (not suspended or expired)
- Receive a Declaration of Conformity with each shipment
- Match the certificate’s product scope to the valve models in the purchase order
Gaoshan Valve’s September 2026 audit cycle confirms that all PED-relevant valve lines remain fully covered for EU shipment through at least the next surveillance window in 2027.
Gaoshan Valve’s Quality System in Practice
Founded in 1975, Gaoshan Valve operates a quality system that is not just documentation — it is the day-to-day discipline that lets a 50-year-old manufacturer keep passing the same audit year after year:
- CE certification under PED 2014/68/EU Module H (current cycle: 2026)
- ISO 9001:2015 quality management certification
- API 600 / API 6D monogram on applicable gate, globe, check, and ball valve lines
- DNV, BV, CCS and other marine / notified-body audits as required by specific projects
For European industrial and energy projects — petrochemical, power generation, district heating, oil and gas — this stack of current certifications is what allows Gaoshan Valve to ship pressure-bearing valves into the EU market without per-shipment retesting by the buyer.
Recommended PED-Certified Valve Lines
| Product Line | PED Category Range | Typical Service |
|---|---|---|
| Gate Valve (resilient seated, API 600) | SEP – III | Water, steam, oil & gas |
| Globe Valve (J41 series) | SEP – III | Steam, process control |
| Check Valve (H44 series) | SEP – II | Pump protection, flow reversal |
| Ball Valve (floating / trunnion) | SEP – III | Isolation, chemical, gas |
| Butterfly Valve (double / triple offset) | SEP – II | Water, HVAC, district heating |
Final category depends on size, pressure rating, and fluid group — confirmed per order.

Frequently Asked Questions
What is PED 2014/68/EU Module H?
Module H is one of the conformity assessment routes in the EU Pressure Equipment Directive. It is a “full quality assurance” route where an EU Notified Body audits the manufacturer’s entire production quality system, not just individual products. The certificate is normally valid for three years with annual surveillance audits in between.
How often is PED Module H surveillance required?
Once per year. The Notified Body must confirm during each annual visit that the manufacturer is still producing CE-marked pressure equipment in compliance with the approved quality system. A failed audit can result in certificate suspension and the loss of the right to affix the CE mark.
Does Module H cover all valve types?
Module H covers the pressure-bearing product families included in the certificate’s technical scope. For Gaoshan Valve, this includes the gate, globe, check, ball, and butterfly valve lines that fall under PED Categories SEP through III depending on size, pressure rating, and fluid group.
What documents come with each EU shipment?
Each shipment of PED Module H–certified valves is accompanied by a Declaration of Conformity referencing the certificate number, the Notified Body’s four-digit ID, the applicable pressure category, and the harmonized standards used. Material certificates per EN 10204 and hydrostatic test reports are provided as required by the purchase order.
Can a pressure valve be CE-marked without Module H?
Yes — through other conformity assessment modules (A, A1, A2, B, C1, C2, C3, D, D1, E, E1, F, G, H1, etc.). Module H is one of the most comprehensive routes, often used for higher-category pressure equipment and for manufacturers exporting a wide range of pressure-bearing products to the EU.
