Thorough and comprehensive testing

That applies not only in the chemical or the oil and gas industries. Depending on the application field or area very different standards and laws may apply. Our tests, with the appropriate tests and approvals for our industry valves, will always provide you with the desired safety. The quality, which is based on our stable processes, has been documented with all the relevant certificates.

RITAG check valves, sampling valves and bottom valves are very thoroughly checked out. We maintain a broad range of instruments for that purpose, ready to use on demand or request. Pressure and leak tests are included, just like low-temperature applications, flow simulations or testing for cleanability.

The acceptance includes standard material testing and on-site inspections, which will be certified according to EN 10204. In addition to the standards intended in the standard testing further special tests, such as dye penetration testing, magnetic particle inspection, ultrasonic examination, radiation testing or materials identification (PMI) can be commissioned.
