Hydrostatic Pressure Test
Shell & body strength to API 598
Quality & Certifications
Quality is verified, not assumed
Every product passes a documented chain of inspection and testing before dispatch — because in process plants, the paperwork matters as much as the part.
Standards & Testing
Built and tested to international standards
From material and pressure to dimensions and function, each check is tied to a recognised standard — and backed by the certificate to prove it.
Inspected · Tested · Certified
Our quality control runs from incoming material to final dispatch. Castings are checked for soundness, trims are matched to service conditions, and finished assemblies are function- and pressure-tested under controlled conditions before approval.
Material traceability
Mill test certificates (EN 10204 3.1) and heat-number traceability on every body and trim.
Hydrostatic & seat testing
Shell and seat pressure tests to API 598 / BS EN 12266 before any valve leaves our store.
Dimensional inspection
Face-to-face, bore and flange drilling verified against ANSI, DIN and API standards.
Documentation & test certificates
Each consignment ships with test reports, IBR forms and conformity documents on request.

Our Quality Process
From incoming material to final dispatch
Every product moves through a documented chain of checks — here is the journey each valve and instrument takes before it reaches your plant.
STEP 01
Incoming Material Inspection
Castings, bar stock and bought-out items checked against grade and documentation on receipt.
STEP 02
Casting & Soundness Check
Bodies examined for soundness and surface defects before they enter machining.
STEP 03
Trim & Service Matching
Seats, stems and seals selected to suit the media, pressure and temperature of your service.
STEP 04
Assembly
Valves and instruments assembled to drawing with controlled torque and clean components.
STEP 05
Hydrostatic & Seat Testing
Shell and seat pressure tests to API 598 / BS EN 12266 to confirm strength and tight shut-off.
STEP 06
Dimensional Inspection
Face-to-face, bore and flange drilling verified against ANSI, DIN and API standards.
STEP 07
Documentation
Test reports, mill certificates (EN 10204 3.1) and conformity papers compiled for the order.
STEP 08
Final Approval & Dispatch
A final check signs off the product and paperwork together before it ships to you.

Mill Test Certificate
EN 10204 3.1 material certificate
Test / Inspection Report
Hydrostatic, seat & functional results
Material Traceability
Heat / batch numbers on body & trim
Certificate of Conformity
Compliance to the agreed specification
Dimensional Report
Key dimensions verified to standard
IBR / Third-Party Certificates
On request, for boilers & critical service
Specific document packages and third-party endorsements can be agreed at the time of order.
Third-Party & Client Inspection
Inspect it yourself — or send your agency
For project and critical-service orders we welcome inspection by recognised third-party agencies and by your own team. Witness testing and stage inspection can be arranged on request.
