Latest Patents

Finlayson holds a patent for a "Cage valve with instrumentation." This invention features a cage valve, flow trim components, and a method for signaling erosion of flow trim. The valve is designed with flow trim arranged across an inlet bore, aligned with an outlet bore. It includes a stationary tubular cage and a flow control member, such as a plug or flow collar, which can slide along the cage's side wall to cover or uncover flow ports. The flow control member is equipped with an end plate that closes the upstream end of the cage. A cavity is formed in the flow control member upstream of the end plate, housing a transmitter, such as a proximity beacon. This transmitter sends a signal indicating the condition of the flow trim, providing critical information for maintenance and operation.
