A gas flow control valve configured to facilitate back-to-back mounting with a second, similarly constructed valve. The gas valve includes a valve body defining an inlet port and an outlet port, the inlet and outlet ports being surrounded by seal forming O-rings of different diameters. Flanges surrounding the inlet and outlet ports are configured with distinct attachment features for accommodating bolts for securing one valve in series with another or with a pipe flange or other auxiliary device, the inlet flange having either a slot 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.
