The additional orifice sizes V and W allow for selection of one or smaller quantity of valves where the API 526 standard would require a multiple installation for large capacity. Based on the general API range V, W orifices are designed for high capacities.
NPS 10” & 12”
Up to 20.7 bar g
Up to 300 psig
The additional orifice sizes V and W are made for very large flow applications.
These capacities are also certified by the National Board of Boiler and Pressure Vessel Inspectors.
