    • A trim insert for a choke assembly is disclosed, wherein the trim insert is a tubular member with a substantially constant inner diameter. A first end of the device is positioned within an adjacent upstream sleeve and a second end is sealingly retained within the discharge channel of the choke assembly. A flange coaxially retains the tubular member between the sleeve and a shoulder of the choke body. The trim insert is made of an erosion resistant material, such as tungsten carbide, hardened steel, or a ceramic. Additionally, the inner surface of the tubular member may be coated with a hardening compound to provide additional erosion resistance.

    • A valve arrangement (10) for reducing the instability of fluid flow in a compressible flow governor valve includes a cutoff plug (12) with a lateral concave surface (14) and an end portion (16) having a substantially circular cross section, and a seat (30) with a convex surface (32). The lateral concave surface (14) and the end portion (16) of the cutoff plug (12) define an abrupt cutoff corner (18). The radius (re) of the end portion (16) of the cutoff plug (12) is less than the radius (Rs) of the seat (30). The radius of curvature (R) of the seat (30) is less than the radius of curvature (rq) of the lateral concave surface (14) of the cutoff plug (12). The configuration of the cutoff plug (12) and seat (30) enhances the annular flow pattern beneath the cutoff plug (12) at all lift positions thus reducing flow instability.

    • A valve, especially a regulating valve, has a throttle point (8), the throttle point (8) being formed by a valve seat (2) and a closure element (3) movable along an axis, and the throttle point (8) being arranged between an axial inflow region (7) and an outflow space (10) which effects a radial diversion. Between the throttle point (8) and the outflow space (10) there is arranged a channel (9), the annular cross-section of which enlarges in the direction of flow preferably steplessly. It is possible, by that means, to obtain a significant reduction in noise.
