ARI-Armaturen Valves & Steam Systems

Isolation valves with metal bellows stem sealing. Compare body materials, connection standards and actuation options.

Globe and special stop valves for process and utility lines, with different body, packing and connection options.

Wafer, lug and double-flanged butterfly valves. Compare manual, geared, pneumatic and electric versions.

Valves for flow adjustment and hydraulic balancing. Review connection and measuring options in the technical catalogue.

Non-return valves to prevent reverse flow. Select according to installation position, opening pressure and fluid conditions.

Pipeline strainers for particle retention and equipment protection. Match screen aperture and material to the application.

Control valves for industrial processes and HVAC. Consider flow characteristic, Kvs and actuator compatibility together.

Pressure reducing valves for a controlled downstream pressure. Select using inlet and outlet pressures and the required flow range.

Regulators for pressure control and pressure maintaining duties. Review the control function and setting range for each series.

Valves and controllers for temperature regulation and limitation. Select sensors and setting ranges to suit the process.

Thermostatic, thermodynamic and float steam trap families. Select the operating principle for condensate drainage and air venting needs.

Auxiliary steam-line equipment, monitoring accessories and insulation solutions. Check series compatibility and installation requirements in the documents.

Manifolds for steam distribution and condensate collection. Match connection counts, sizes and layouts to your application.

Safety valves for overpressure protection. Fluid, set pressure and required relieving capacity are determined for the project conditions.

Pneumatic actuators and positioners for valve control. Consider stroke, control signal, air supply and fail-safe position together.

Electric drives for valves. Match force, stroke, supply voltage and control options to the valve series.

Stations for steam pressure reduction and condensate recovery. Capacity, controls and plant connections are assessed for each project.
