Yes. All valve testing requirements can be made available, including MTR’s, NDE, Pressure Testing, Radiography Testing, Magnetic Particle, Dye Penetrant, PMI, Positive Material Identification, Hardness Testing, and Failure Analysis.

Yes. Only the first letter in the model number has changed. Form, fit, and function remain the same.
