A method of custom manufacturing a fluid pressure reduction device for use in a process control valve. The method includes creating the fluid pressure reduction device using an additive manufacturing technique, which generally includes forming a body and forming a plurality of flow paths in the body. The body has an inner wall and an outer wall spaced radially outward of the inner wall. The flow paths are formed in the body between the inner wall and the outer wall of the body. Each of the flow paths includes an inlet section formed in one of the inner and outer walls, a curved intermediate section, and an outlet section formed in the other of the inner and outer walls.

The present invention is a differential pressure loss valve comprising a valve housing that incorporates: a sleeve that incorporates a continuous cylindrical helical thread formed in the inner surface thereof; and a cylindrical channel carrier incorporating a cylindrical helical thread formed in the outer surface thereof. When the channel carrier is positioned within the sleeve a portion of the sleeve cylindrical helical thread integrates with the channel carrier cylindrical helical thread, and a composite channel is formed there-between. The geometric configuration of the composite channel is consistent throughout such composite channel, although the geometric configuration may differ in individual embodiments of the present invention. Fluid can flow within the valve between an inlet port incorporated in the sleeve and an outlet port incorporated in the valve housing and through the composite channel, or any portion thereof between the inlet port and outlet port, if any.

A control valve (1) comprising a valve body (2) having an inlet opening (3) and an outlet opening (4) for a fluid; a obturator (6) placed within the valve body (2) between the inlet and outlet openings (3, 4); recovery means (5) configured to transfer kinetic energy and/or potential energy extracted from the fluid out of the valve body (2), the recovery means (5) comprising a rotating element (7) placed within the valve body (2) downstream of the obturator (6) and configured to be put in rotation by the fluid.

A pressure relief valve assembly includes a carrier, a valve, and a baffle. The carrier includes a first end and a second end. The first end defines a first opening. The second end defines a second opening. The carrier defines a flow passage extending from the first opening to the second opening. The valve is supported by the carrier and is operable in an open position and a closed position. In the open position, the valve permits a flow of fluid through the first opening. In the closed position, the valve inhibits the flow of fluid through the first opening. The baffle is disposed in the flow passage. The baffle and the carrier collectively define a flowpath extending through the flow passage.
