A flowline power generator especially adapted for use on a conduit or flowline carrying petroleum or hydrocarbon products is disclosed. A valve body incorporated in the flowline redirects at least a portion of the fluid flowing through the flowline into engagement with a turbine which drives an electrical generator. A gate valve is provided for bypassing the turbine to permit all of the flow in the conduit to bypass the power generator, and yet provide substantially the same pressure drop to protect downstream equipment from high-pressure surges. In the bypass configuration, the power generator can be repaired or completely removed. The valve body can be incorporated into the flowline with no power generator attached, and power generators can be subsequently installed at prescribed locations along the conduit.

The method of selectively driving a fluid pressure engine by fluid pressure derived from a primary conduit comprising: the steps of inserting in said primary conduit a valve housing having noncommunicating inlet and outlet passages respectively communicating with parallel first and second flow passages terminating in a planar face of the valve housing; disposing the inlet and outlet passages of a fluid pressure engine in juxtaposed relation to said planar end face; rotatably and sealably mounting a valving disk intermediate said planar end face and said fluid pressure engine inlet and outlet to initiate fluid flow through the fluid pressure engine in a first angular position and to terminate fluid flow through the fluid pressure engine in a second angular position; providing a bypass fluid passage in said valving disk operative to interconnect said inlet and outlet passages in said second angular position; and proportioning said bypass fluid passage to produce substantially the same pressure drop as when fluid flows through said flow pressure engine, thereby protecting downstream apparatus from any pressure surge when fluid flow through said fluid pressure engine is terminated by shifting of said valving disk to said first position.
