Embodiment Construction

[0067] figure 1 with figure 2 A process valve 10 is shown which comprises an actuation unit 12 according to the first embodiment and a valve unit 14 which is indicated only symbolically. The actuation unit 12 may also be referred to as a pilot unit of the valve unit 14 .

[0068] The actuating unit 12 comprises a pilot valve unit 16, a separate removable seal 18 and a piston 20 configured for regulating the process valve 10, more precisely the valve unit 14, and is connected to the first pressure chamber 20a adjoins the second pressure chamber 20b.

[0069] The two pressure chambers 20a, 20b are arranged on opposite sides of the piston 20 and are preferably arranged in a cylinder, not referred to in detail, in which the piston 20 is also guided.

[0070] Furthermore, an elastic element 20c is arranged in the second pressure chamber 20b and is a spring in the illustrated embodiment. The elastic element 20c pushes the piston 20 in the direction of an end position correspond...

Abstract

An actuating unit 12 for a process valve 10 is described, which comprises a pilot valve unit 16, a separate removable seal 18 arranged between two parts through which a fluid can flow, and a piston 20configured for the adjustment of the process valve 10. The seal 18 has through openings (18a-18g) for the passage of fluid, and the adjacent parts have holes (21a-21h), such that different holes (21a-21h) are in fluid communication with each other via the through openings (18a-18g) or are fluidically separated due to an intermediate wall portion of the seal 18 depending on the fitting position ofthe seal 18. A process valve 10 having such an actuating unit 12 is furthermore described.

Description

technical field [0001] The invention relates to an actuation unit for a process valve and to a process valve with the actuation unit. Background technique [0002] Such actuating units and process valves are known in the prior art and are available on the market in various variants. [0003] On the one hand, the variety of variants results from the use of actuation units for process valves and process valves in a wide range of applications with different requirements. Furthermore, actuating units and process valves with different properties are required in certain fields of application. [0004] Process valves which close without a control signal (so-called “normally closed” valves, abbreviated: NC valves) may be required, for example, within applications. Process valves that open without a control signal (so-called "normally open" valves, abbreviated as NO valves) may additionally be required in the same application. The control signal is in particular an electrical or p...
