V Tech Valves & Controls

Quality Compliance

• ISO 9001:2015 Certification: V-MAK's adopted standard for Quality Management.

  • Infrastructure for Maintaining QMS Documentation & Records.

  • Continual Improvement Framework (PDCA Cycle).

• Organizational Structure for Quality:

  • Roles, Responsibilities, and Authority for Quality Control Personnel.

  • Quality Reporting Hierarchy.

The application of standards from the initial design phase.

• Code Compliance Standards:

  • ASME BPVC Section VIII (Design and Fabrication of Pressure Vessels).

  • API 520 / API 526 (Sizing, Selection, and Flanged Steel SRVs - especially for Safety Valves).

  • ASME B16.34 (Valve Design, Materials, and Pressure/Temperature Ratings).

• Control Valve Standards (PRV/PCV/ACV):

  • FCI/ANSI (e.g., FCI 70-2) for Seat Leakage Classification.

  • Standards for Flow Capacity and Rangeability.

• Traceability Infrastructure:

  • System for Material Test Certificate (MTC) verification and digital archiving.

  • Component-Level Serialisation and Tracking (linking test results to final valve).

Ensuring the integrity of materials used in your critical valves.

• Raw Material Inspection & Segregation:

  • Dedicated Area for Incoming Material Inspection.

  • Positive Material Identification (PMI) Equipment and Procedure (for high-alloy/corrosion-resistant valves).

• Weld Procedure Qualification (WPS/PQR):

  • Infrastructure for maintaining and certifying welding procedures (if applicable).

  • Welder Performance Qualification (WPQ) Records.

• Non-Destructive Testing (NDT) Protocol:

  • Facilities/Vendor Management for RT, UT, MPT, DPT as required by standards (e.g., ASME B16.34).

Validating the final product's performance against mandated leakage and pressure criteria.

• Pressure Testing Compliance:

  • Hydrostatic Shell Testing (e.g., 1.5 times the MAWP per ASME standards).

  • Seat Leakage Testing (e.g., per API 527 for SRVs, or FCI Classifications for Control Valves).

• Calibration Infrastructure:

  • Certified Test Benches for Safety Valve Set Pressure Calibration.

  • Traceability of all Calibrating Instruments and Master Gauges.

• Post-Test Documentation:

  • Digital System for Generating Test Certificates and Certificate of Compliance (COC).

• Export Readiness:

  • Compliance with PED (CE Marking) requirements for European exports (if applicable).

  • Compliance with IBR (Indian Boiler Regulations) for steam service products.

• PSU / Government Sector Documentation:

  • Infrastructure dedicated to managing and delivering stringent client-specific inspection and documentation dossiers.

  • Third-Party Inspection (TPI) facilitation and record keeping.
