High-quality ball valve, API608, VQR2AL00, RF, 150LB
Thread Content
Could you explain what VQR2AL00 means? Also, can it be determined from \"Ball Valve API608 VQR2AL00 RF 150LB\" what material is used?
For the model numbering method used by a design institute, you need to know that institute’s model system and then look it up
American standard valve standards. . . . . . . . . . .
Unlike national standard valves, American standard valves do not have a numbering system; detailed requirements are needed regarding the valve’s structure and materials. VQR2AL00 is the valve coding code of the design institute; each letter or digit represents a different meaning, and only the relevant design specifications can be referred to.
This must be a model from some valve manufacturer
Ball valve API608 VQR2AL00 RF 150LB, in accordance with the API608 standard; the VQR2AL00 designation is assigned by the design institute, and the client can provide the corresponding table from that institute.
VQR2AL00: V – Valve; Q – Ball valve; R – The sealing surface is of type RF; 2 – Pressure rating: 150Lb; A – Material of the valve body (for example, A refers to carbon steel A105 or WCB, while B refers to 304 or CF8); L – Material of the internal components (L is likely 13Cr/PTFE); 00 – Code for any special requirements regarding the valve (for example, 00 indicates no special requirements, 03 indicates it’s designed for use with oxygen, etc.). Since it resembles the valve coding system used by a certain engineering company, this is just an estimate for reference only. The people upstairs are right; it is necessary to require coding instructions to be provided as well.
