A choke valve includes a choke body and a choke trim disposed within the choke body. The choke trim also includes an insert defining a plurality of positive beans and a plate defining an aperture. The plate is configured to contact and to rotate relative to the insert to cover and uncover the plurality of positive beans to adjust a fluid flow through the choke valve.

The invention relates to a valve device for controlled passage of a medium, in particular in the high-pressure range, which is provided with: a housing (15) having a bore (11) and at least one inlet opening (12) and an outlet opening (13); a pressure chamber (14) which is formed in the bore (11) and can be acted upon by the medium; and a valve needle (16) which is movable to and fro therein and has a conical tip (16′). A guide means (20) for the valve needle (16), by means of which the valve needle (16) with its circumferential region (16″) is guided directly at the conical tip (16′) almost without play and concentrically with respect to the valve seat (17) until it is almost in the closed position, is located in a valve seat (17) in a valve seat block (18). This guide means (20) has passage openings (24) for the passage of the medium from the pressure chamber (14) into the outlet opening (13). Very precise guiding of the valve needle is thus achieved at the front at the tip thereof, so that the service life of the valve device can be increased.

The present invention solves bore wear due to inefficient design of OEM pressure regulator valve through an improved pressure regulator valve with lands having narrower diameters and longer lengths, the lands additionally having a grooved design, and a second land having a beveled edge to stabilize fluid regulation. Narrower lands allow for better ATF lubrication in a bore. Longer lands allow for the valve to be dropped into a bore to interact with non-damaged lengths of the bore without further machining. The beveled edge regulates pressure, further reducing bore wear.

A fluid flow control device includes a valve body defining an inlet, an outlet, and a fluid flow path extending therebetween, a valve seat ring coupled to the body that defines an orifice through which the fluid flow path passes, a cage coupled to the body that defines an interior bore, a control element slidably disposed within the interior bore of the cage, and a particle catcher at least partially disposed within an interior bore of the control element. The particle catcher includes a particle catcher body that defines an inner flow path and at least one particle catcher passage through which the fluid flow path passes. An outer surface of the particle catcher and an inner surface of the control element form a particle catching portion. The at least one particle catcher passage directs the fluid flow path downwardly into the particle catching portion.

An anti-cavitation valve assembly includes a seat positioned within a fluid pathway between a fluid inlet and outlet of a valve. Spaced apart elongated seat apertures are formed in a circumferential wall of the seat that have a varying opening width along a length thereof to direct fluid flow into an inner seat chamber of the seat. A disc guide is slidably movable relative to the seat and has a wall having spaced apart disc guide apertures formed therein. A tortuous fluid flow pathway is formed as fluid enters through the seat apertures, into the inner seat chamber, and exits through the disc guide apertures to minimize fluid cavitation.
