Abstract: A valve unit comprises an operating piston for closing and opening a connection between a process pressure input line and a process pressure output line, at least one control line and at least one control chamber for controlling the operating piston. The operating piston has a closing ring which in the closed state of the connection sealingly abuts a valve seat of the valve housing (or the valve housing has a closing ring which in the closed state of the connection sealingly abuts against a valve seat of the operating piston). The valve seat consists of a softer and more elastic material than a circumferential sealing edge abutting said valve seat. An annular sealing element is present which comprises the valve seat. The sealing element has the shape of a truncated cone with an outwardly widening base.

Abstract: A system for exercising a valve may comprise a valve exercising apparatus having inoperative and operative conditions, a transitional event when the apparatus transitions from the inoperative to the operative condition. The exercising apparatus may comprise a valve exercising motor for connecting to the valve and a controller assembly for controlling operation of the motor. The controller assembly may operate in a manual control mode and an automated control mode, with the manual control mode being characterized by operation of elements of the exercising apparatus being initiated by manual input from the operator, and the automated control mode being characterized by operation of elements of the exercising apparatus being initiated by the controller assembly. The controller assembly may be configured to operate the apparatus in a startup condition at the occurrence of the transitional event, and the startup condition may correspond to the manual control mode.

Abstract: A closure member is configured for use in a valve. These configurations may include a plug with grooves or “flutes” that extend along its length. Inserts in the flutes may comprise materials, like ceramics, that are different than the material that forms the core or base portion of the plug. These inserts are useful to slow erosion of the device, particularly in the flutes, which form an outwardly-facing surface that is subject to high velocity flow in the valve. This feature can extend service life of the plug, particularly in highly-erosive process fluids, like particle-entrained fluids commonly found in hydrocracking or refining operations.

In the second position, the ports are fluidly isolated from each other. An external surface of the fluid switch is separated from an internal surface of the chamber by a first micro-gap. Another external surface of the fluid switch is separated from another internal surface of the chamber by a second micro-gap. The first micro-gap and the second micro-gap are fluidly coupled to the chamber, and each have a respective size of less than about five micrometers.
