Stockham B-120 Gate Valve

Stockham B-120 Gate Valve, Fig. B-120, is a 1-1/4 inch brass threaded gate valve assembly rated for 300 CWP and 50 SWP. This model belongs to Stockham’s B-120 family and uses threaded end connections designed for inline installation with compatible piping components. The B-120 designation identifies the specific valve configuration within Stockham’s line, while the brass threading specifies the connection type. The 300 CWP and 50 SWP ratings reflect the pressure capabilities of this assembly under cold-water and steam service conditions, respectively.
