Manufacturing & Branding Capabilities

Four distinct capabilities — each with a defined scope, operational reality, and documentation outcome.

Vajra-Branded Industrial Manufacturing

Selected valve types are manufactured under the Vajra Industrial Solutions brand to our engineering specifications, quality standards, and marking conventions. Every production stage is controlled under the Vajra Quality Assurance Plan — from material receiving through pressure testing and pre-despatch inspection.

  • Vajra engineering specification governs: material grades, dimensional standards, test requirements, marking
  • Manufacturing executed to Vajra QAP (Quality Assurance Plan) — no deviations without QC sign-off
  • Every batch tested per API 598 before release — hydrostatic shell, seat leakage, dimensional
  • Vajra name, logo, and tag number marked on body per marking specification
  • EN 10204 3.1 MTCs traceable to heat number and Vajra order reference
  • Full traceability maintained from raw material to finished valve

Industrial Valve Manufacturing Capabilities

Our industrial manufacturing capabilities cover the full range of valve types for critical applications: ball, gate, globe, butterfly, check, plug, needle, safety valves, strainers, and actuated valve assemblies — engineered to API, ASME, and EN standards.

  • Manufacturing to API 6D, API 609, ASME B16.34, BS 5351, and EN standards
  • Exotic material capability: Hastelloy C-276, Duplex 2205, Super Duplex 2507, Inconel 625, Monel 400
  • IBR-certified manufacturing for steam service valves — Form III-C / IV documentation
  • Fire-safe design per API 607 / API 6FA — qualified valve series available
  • ATEX Zone 1 and Zone 2 actuated valve assemblies — pneumatic, electric, hydraulic
  • Cryogenic service: extended bonnet, A352 LCC, BS 6364 low-temperature design

Private Label & Custom Branding

For buyers requiring valves branded under their own company name or project identity, Vajra provides comprehensive private-label capabilities. This includes body marking, tagging, packaging, and full documentation alignment to the buyer's identification system.

  • Body marking: cast-in or stencilled company name, logo, or project identifier
  • Tag plate: stainless steel tag with buyer's tag number system and service details
  • Colour coding: RAL or custom paint colour per buyer's plant coding standard
  • Packaging: customised to buyer's brand on outer carton and crate stencilling
  • Documentation: buyer's tag system and PO reference used throughout MTC and test reports
  • Confidentiality: NDA available on request for all private-label arrangements

Documentation Under Vajra Brand

All documentation for Vajra-branded products is issued under the Vajra Industrial Solutions name — material test certificates, inspection reports, test certificates, and compliance statements — creating a single, consistent identity and accountability chain for the buyer.

  • EN 10204 3.1 MTCs: issued in Vajra's commercial format, referencing Vajra order number
  • Hydrostatic test reports: Vajra QC engineer signature, Vajra reference number
  • Dimensional inspection reports: Vajra drawing reference, Vajra QC sign-off
  • Compliance declaration: Vajra Industrial Solutions as the named responsible party
  • Warranty: issued under Vajra Industrial Solutions — single point of accountability
  • IBR Forms: where applicable, under Vajra's commercial identity with licensed TPI

From Specification to Despatch

Every Vajra-branded order follows this 6-stage production and QC flow.

01

Engineering Specification

Vajra defines: material grade, dimensional standard, test requirements, marking, documentation scope. Approved specification governs every production stage.

02

Controlled Manufacturing

Production executed to Vajra engineering specification. Material receiving inspection at intake. In-process checks per Vajra QAP at defined stages.

03

QC & Pressure Testing

API 598 shell and seat test. PMI on alloys. Dimensional inspection. Visual inspection. TPI witness if specified.

04

Marking & Tagging

Vajra brand marking applied. Tag plates fitted. Colour coding per specification. Bore end caps and flange protectors fitted.

05

Document Compilation

EN 10204 3.1 MTCs, test reports, inspection records compiled under Vajra reference. MDR for EPC orders.

06

Despatch

PDI clearance. Packing list finalised. Documents emailed same day as shipment. Tracking detail provided.

Manufacturing Quality Controls

Vajra QAP (Quality Assurance Plan) defines inspection and testing requirements for every product line
Material receiving inspection: heat number verification, PMI on alloys, hardness check for NACE-spec materials
In-process inspection: bore gauging, thread gauging, seat assembly verification
Final pressure testing per API 598: shell (1.5× rated), seat leakage (Class IV standard; V or VI on request)
Dimensional inspection per ASME B16.5, B16.10, B16.47 — recorded against drawing
Visual inspection per MSS SP-55 — casting quality, marking verification, end protection
TPI by SGS, BV, TUV, DNV, Intertek, CEIL — ITP prepared before production, hold points enforced
EN 10204 3.1 MTCs traceable to heat number — issued before despatch, not after
