Abstract
A valve assembly for a metered fluid flow such as gas to a facility for utilizing the fluid. The valve assembly includes a housing having a bore. The bore has a first inlet opening connected to a source of fluid and a first outlet opening connected to a meter. the bore has a second inlet opening connected to the meter and a second outlet opening connected to the facility. A piston which contains a fluid passageway is slidably mounted within the bore for selective movement to at least two operating pistons, including a metered fluid flow position and a fluid flow meter bypass position. The fluid passageway within the piston has an inlet port and an outlet port. When the piston is in the metered fluid flow position, the first inlet opening is in fluid communication with the first outlet opening and the second inlet opening is in fluid communication with the second outlet opening to enable fluid from the source to flow through the meter to the facility. When the piston is in the fluid flow meter bypass position, the inlet opening is in fluid communication with the inlet port and blocked from fluid communication from the first outlet opening and the outlet port is in fluid communication with the second outlet opening and blocked from fluid communication with the second inlet opening so that fluid from the source is diverted through the fluid passageway to the facility. The valve assembly can be selectively moved to any one of its operating positions within the housing.
