armaturvalen

Armaturvalen is a term found in some European engineering texts and vendor catalogs for a valve assembly used in automated process control. The phrase combines "armatur" (valve or instrumentation) with "valen" (valve) and is not standardized in English-language literature; usage is regional and varies by manufacturer.

A typical armaturvalen consists of a valve body coupled to an actuator and a control or monitoring package. The actuator provides the motion to open or close the valve, while the attached instrumentation can include position indicators, limit switches, and sometimes process sensors. The assembly is designed to operate within a control loop, regulating flow, pressure, or direction of a process fluid in response to signals from a controller.

Variants cover several valve types integrated into instrumentation assemblies, including globe, ball, diaphragm, or needle configurations. Actuation is commonly pneumatic, electric, or hydraulic, and may include a positioner to ensure the valve reaches the commanded opening. Interfaces follow industry standards to enable compatibility with controllers and other field devices.

Applications span chemical processing, oil and gas, power generation, water treatment, and HVAC systems, where reliable, compact valve packages optimize control with reduced installation complexity.

Notes: Terminology varies by language and region; when specifying armaturvalen, engineers typically provide valve type, size, actuation method, and interface standard. See also valve, actuator, control valve, instrumentation.
