摘要： A valve, in particular of an extrusion blow moulding machine or a stretch blow moulding machine for manufacturing hollow bodies, has a movable piston, a process fluid region and a compensation chamber. The piston has a free front face which faces the process fluid region with a circumferential outer sealing region. At least one connecting channel connects the process fluid region to the compensation chamber. The free front face of the piston has an elevation, which is surrounded by the outer sealing region. The elevation protrudes over the outer circumferential sealing region. The valve permits a rapid and precisely timed opening.

摘要： A gas valve, in particular a metering valve for a gaseous medium, having a valve washer (10) which is arranged in the gas valve so as to be able to move with respect to a longitudinal axis (8), and having a valve plate (12) with a valve seat (19) formed thereon, wherein the valve washer (10) interacts with the valve seat (19) for opening and closing the gas valve, and having a first circumferential sealing edge (30) between the valve seat (19) and the valve washer (10). The valve washer (10) has a central opening (13) through which the gaseous medium passes, wherein the first circumferential sealing edge (30) surrounds the central opening (13) and wherein, in the central opening (13), there is formed a first pressure face (25) upon which the gaseous medium acts in the closing direction. Furthermore, there is arranged on the valve washer (10) a second pressure face (26) which is formed radially outside the first circumferential sealing edge (30) and on which the gaseous medium also acts. The first pressure face (25) and the second pressure face (26) are connected via a connection passage (15; 17; 24) formed in the valve plate (12).

摘要： Valve trim for a valve includes a valve plug having one or more balance ports located along the outer surface of a tapered nose portion of the valve plug. Each balance port is located to be downstream of the throat and spaced from the tip of the tapered nose portion of the valve plug. The valve trim may be use, for example, in a high recovery angle body valve. A high recovery valve with the valve trim may have better recovery performance as well as a smaller spike in stem force through the choked flow transition point. A method of reducing stem forces on a valve stem of sliding stem valve is also provided.

摘要： The disclosed embodiments include a pressure balance valve that solves one or more problems associated with existing designs. For example, in one embodiment, a pressure balancing valve assembly is disclosed that provides a low cost frictionless assembly that is constructed to not seal the leak path between an inlet port and an outlet port. Instead, this leak path is minimized with small angle tapered plunger and a precision bored annulus to provide a defined area for the pressure drop to occur and to limit the flow from the inlet to the outlet.

摘要： A trim assembly is provided with a cage with an internal surface and a cage port. A plug having an external surface is disposed in the cage and is operable between a closed position, a pressure balancing position and an open position. The trim assembly also includes a low friction flow restrictor disposed between the cage and the plug and a pressure energized seal disposed between the cage and the plug. A seal balancing volume defined by the internal surface of the cage, the external surface of the plug, the low friction flow restrictor and the pressure energized seal is provided. The seal balancing volume is in fluid communication with the cage port through the low friction flow restrictor and is maintained at a seal balancing volume pressure. The trim assembly further includes a pressure control assembly configured to vent the seal balancing volume.
