ISO 9001:2015 Export Oriented Unit UK export since 2019 NABL-lab CMM certification

A proven export supplier to the valve industry. Shree Lakshmi Engineering has been a dedicated supplier to a leading UK valve manufacturer since 2019, producing mission-critical and subsea valve components. As an Export Oriented Unit, we build to international quality standards with full material traceability and third-party dimensional certification.

Valve & subsea components we machine

Made to your drawing, in the corrosion- and pressure-resistant grades valve service demands.

Valve bodies & bonnets

High-pressure and subsea valve bodies and bonnets in stainless, duplex and super duplex.

Stems, seats & internals

Precision-turned stems, seats and trim components with tight sealing tolerances.

Manifolds & hose fittings

Hydraulic manifolds, hose fittings and pressure-rated connectors.

Materials for valve & subsea service

Valve and subsea duty punishes the wrong material choice. We machine the grades specified for pressure integrity and corrosion resistance:

SS 316 / 316LGeneral corrosion resistance, marine and process service
Duplex / Super DuplexHigh strength + chloride/pitting resistance for subsea
InconelHigh-temperature and severe corrosive environments
SS 304 / Brass / AluminiumGeneral and lower-pressure valve and fitting duty

Machining & verification

  • Turning: five FANUC CNC turning centres to Ø320 mm × 500 mm — ideal for valve stems, seats and bodies of revolution.
  • Milling: four VMCs (800 × 500 × 500 mm, 200 mm 4th axis) for bodies, bonnets and manifolds.
  • 5-axis: simultaneous 5-axis via qualified subcontract partners under our ISO 9001:2015 system.
  • Tolerance: ±0.005 mm on selected features; ±0.02 mm general; finish from Ra 0.2 µm.
  • Verification: in-house Mitutoyo metrology + 2D height master; full CMM certification via an external NABL-accredited laboratory.

Built for export procurement

International buyers audit their suppliers, and our documentation is built for it: material traceability, first-article inspection reports, and third-party NABL-accredited CMM certification against your GD&T. We are an Export Oriented Unit and quote in INR, USD or GBP with export-ready paperwork.
