Your Last Line of Defense Against Overpressure

Pressure Safety Valves (PSVs) — also called Pressure Relief Valves (PRVs) — are the final barrier protecting your vessels, pipelines, and equipment from catastrophic overpressure events. A valve that fails to open at the correct set pressure — or fails to reseat properly — can lead to explosions, fires, and fatalities.

Regular inspection, testing, and calibration of PSVs is not optional. It is mandated by international standards including API 576, ASME Section VIII, and local regulatory authorities. EnvironmSafe's certified test bench and trained technicians ensure your PSVs perform exactly as designed — every time.

Our PSV Services

End-to-end pressure safety valve lifecycle management — from initial inspection through testing, calibration, maintenance, repair, and certification.

PSV Inspection

Comprehensive visual and dimensional inspection of pressure safety valves to identify wear, corrosion, damage, and non-conformances before they become critical failures.

  • Visual & dimensional inspection per API 576
  • Body, disc, seat, and spring condition assessment
  • Corrosion, erosion & damage mapping
  • Nameplate & tag verification
  • Inspection report with recommended actions

PSV Testing (Set Point & Tightness)

Functional testing on our certified test bench to verify set pressure, pop action, blowdown, and seat tightness — the only way to confirm a PSV will activate at the correct pressure.

  • Set pressure (cracking / pop pressure) verification
  • Blowdown measurement & adjustment
  • Seat tightness testing per API 527
  • Cold differential test pressure (CDTP) calculation
  • Certified test bench — traceable calibration

Calibration

Precision calibration of PSV set points to manufacturer specifications and process requirements — performed on our certified, traceable test bench with full documentation.

  • Spring adjustment to achieve correct set pressure
  • Calibration per manufacturer data sheets
  • CDTP adjustment for back-pressure & temperature
  • Calibration certificate with traceability chain
  • Seal & tag application after calibration

Maintenance & Overhaul

Complete disassembly, cleaning, part replacement, and reassembly of pressure safety valves — restoring them to full operational specification.

  • Full disassembly & internal cleaning
  • Seat & disc lapping for gas-tight seal
  • Spring inspection & replacement
  • Gasket, O-ring & soft-parts replacement
  • Reassembly, testing & re-certification

Repair

Expert repair of damaged or degraded pressure safety valves — extending asset life and restoring safe, reliable performance without costly full replacement.

  • Body damage assessment & repair
  • Seat reconditioning & resurfacing
  • Spindle, disc & guide replacement
  • Anti-corrosion treatment & coating
  • Post-repair functional test & certificate

Certification & Documentation

Complete traceability documentation — from inspection findings through testing results, calibration certificates, and maintenance records — for regulatory compliance and audit readiness.

  • Inspection & test reports
  • Calibration certificates (traceable)
  • Maintenance & repair history records
  • PSV register management
  • Regulatory compliance documentation

Purpose-Built. Precision-Calibrated. Certified.

EnvironmSafe's certified PSV test bench is purpose-built for accuracy and compliance — the only facility of its kind in the region, operated by trained technicians and calibrated to traceable international standards.

Precision Measurement

Our test bench uses precision pressure transducers and gauges calibrated to NIST-traceable standards — ensuring set pressure measurements accurate to ±0.5%.

Wide Pressure Range

Capable of testing PSVs across a wide range of set pressures — covering the majority of industrial, commercial, and process applications encountered in the field.

Full Traceability

Every test and calibration generates a certificate with full traceability to the test bench calibration records — ready for regulatory audits, insurance inspections, and management review.

Trained Technicians

Our technicians are trained in PSV inspection and testing per API 576, with hands-on experience across diverse valve types, sizes, and manufacturers.
