摘要： An anti-cavitation seat which is disposable between an inlet and an outlet of a pressure reducing valve, and including a plurality of inlets causing fluid to flow into a converging pathway to reduce pressure of the fluid. The inlets form a tortuous path for a portion of the fluid flowing into the anti-cavitation seat, so as to further reduce the pressure of the fluid. A standard stem assembly is used in conjunction with the anti-cavitation seat to alter the flow of fluid through the valve.

摘要： A rotary valve for fluid flowing in a pipe. The valve has a body provided with upstream and downstream segments located on either side of a central recess constituting a seat into which a rotary sealing element, including a through-channel, is inserted. A decompression insert is arranged in the upstream segment and provided with a first cylindrical section having an outer cross-section equal to the cross-section of the upstream segment, a second cylindrical section having a cross-section that is narrower than the first cylindrical section, and a third section, referred to as frusta-conical connection section, for connecting the first and second sections. The decompression insert has a plurality of radial openings provided in at least one of the walls of the second and/or the third sections in order to diffuse the fluid toward the through-channel of the sealing element during a partial opening phase of the rotary valve.

摘要： A speed control valve for fluid motors in which the flow passages through the valve body are formed by a first bore extending part way into the valve housing, a second bore of smaller diameter extending toward the first bore, a third bore extending transversely of the first and second bores and intersecting the first bore, a fourth bore connecting the second and third bores, and a valve element seating on the intersection of the third and fourth bores to control flow of fluid between the first and second bores. There may also be a fifth bore connecting the first and fourth bores and a second valve element seating on the intersection of the fourth and fifth bores to further control flow of fluid between the first and second bores.
