FARRIS SAFETY VALVE MODEL NO. 1896M

FARRIS SAFETY VALVE MODEL NO. 1896M

FARRIS SAFETY VALVE MODEL NO. 1896M

(OP)
I was looking on test certificates of FARRIS SAFETY VALVE MODEL NO. 1896M, which has bronze body, bonnet & SS stem, spring. Test certificates for body, bonnet & disc only provided by the manufacturer. That too, they have provided 3.1 certificate for body, bonnet & 2.1 certificate for disc. I could not find test certificate for stem & guide. This being safety valve, I am more concerned to get 3.1 certificates for stem, guide & spring. Also, 3.1 certificate for disc. Can any one suggest if my above argument is correct.

Preliminary answer: You can test and certify any safety valve at a certified testing company, both for performance and for material. This is of course a question of cost, compared to a completely new valve.

Your demands for certifications should however be specific for your use, depending on your application and the plant's requirement and safety rules and regulation.

Correct sizing, piping layout, maintenance and regular performance tests are often more important than a material certificate.
