Beschreibung
Zusammenfassung:	A gas flow control valve (10) configured to facilitate back-to-back mounting with a second, similarly constructed valve (84). The gas valve includes a valve body (12) defining an inlet port (22) and an outlet port, the inlet and outlet ports being surrounded by seal forming O-rings (14, 16) of different diameters. Flanges surrounding the inlet and outlet ports are configured with distinct attachment features for accommodating bolts (94) for securing one valve in series with another or with a pipe flange or other auxiliary device, the inlet flange having either a slot (144) dimensioned to hold and prevent rotation of a bolt head or nut, or a clearance slot permitting use of a wrench, and the outlet flange having the other slot configuration.
