Since 1988 DAFRAM's Quality Management System has been certified as compliant to ISO 9001 requirement by accredited body RINA Services S.p.A. and it has been maintaind up to today. Quality Management System has been extended and improved by obtaining specific product certifications also to follow new technical and market needs.

In 2006 DAFRAM improved its Management System by including also environmental aspects on it and obtaining the ISO 14001 certification by accredited body RINA Services S.p.A..

At last in 2011 Company implemented a Health and Safety Management System certified as compliant to OHSAS 18001 requirements by accredited body RINA Services S.p.A..

Today the whole process of ball valves design, production and after-sales is covered by Management System that is certified and audited by accredited external bodies on the basis of timing defined by following standards of reference:

According to written procedures the whole manufacturing process of ball valves is continuously monitored by the following inspections and tests performed during:

  • Customer evaluation and monitoring
  • Checking of raw incoming materials certification
  • Inspection of manufacture of valve components
  • Pressure tests
  • Functional tests
  • Non destructive tests
  • Final inspection of finished valves

If specified by the purchaser, the following different tests can be berformed to verify valve properties and performances, to verify material chemical composition or mechanical properties, to qualify valves to special working conditions or to long working life:


  • Pressure test at high/low temperatures
  • Low e and High pressure seat gas test in accordanc with Annex C of API 6D
  • On customer request pressure tests can be performed in accordance with other standards like API 598 and EN 12266-1
  • Anti static test
  • Torque test. Torque value is verified during this test as well.
  • Functional valve test or functional valve and actuator test.
  • Fugitive emission test to ISO 15848 or to other standards
  • Paint dry film thickness check
  • Insulating coat testing by holiday detector ISOLTEST HD93
  • Cavity relief test
  • Cryogenic test down to minus 196 °C
  • Strain gauge test
  • Hyperbaric test
  • API PR2 test


Every DAFRAM valve identified by a univocal Serial Number, will be delivered complete with EN 10204 3.1 material certificate of pressure containing parts and 3.1 certificate of pressure tests. In addition, all other certificates concerning special valve tests, destructive or non destructive tests and qualification tests according to purchase order requirements will be included. On customer request a third part inspector can witness every test and issue a certificate in accordance with EN 10201 3.2.
