Threaded Outlet Type Valves With Handwheels

Threaded outlet valves for large cylinders are separated into four Where size permits, it is recommended that valves, nuts and
basic divisions – Internal Thread (INT), External Thread (EXT), nipples be marked with the appropriate CGA number. Left Hand
Right Hand Thread (RH), and Left Hand Thread (LH). Further Threads (LH) are identified by a V-groove in the hexagonal nut.
separation is made within each division by varying the diameter Each outlet provides for screw threads which do not seal, but
of the threads, and the size and shape of seats and nipples for merely hold the nipple against a seat in the valve outlet or against
any given thread size. a washer.
