ARI-Armaturen Control Valves: Engineering Analysis and Specifications

Engineering Analysis of ARI-Armaturen Control Valves

For over 70 years, the German manufacturer ARI-Armaturen Albert Richter GmbH & Co.KG has been a key developer and supplier of industrial shut-off and control valves. The brand's products, supplied by EV Group China, are integrated into technological processes at facilities in more than 60 countries worldwide. The assortment includes high-tech valves with intelligent ARI-PACO actuators, specialized seals, and noise reduction units, making them indispensable in critical applications such as power generation, petrochemicals, pharmaceuticals, and HVAC systems.

Key Technical and Operational Parameters of ARI-Armaturen Valves

  • Precise Flow Control: A control range of up to 50:1 guarantees stability of technological parameters under dynamic loads.
  • Minimization of Cavitation and Noise: The use of multi-stage trims and perforated plugs reduces erosive wear in high-velocity steam and gas media.
  • High Sealing Class: Compliance with Class IV according to DIN EN 60534-4 ensures minimal leakage in the closed position.
  • Thermal Resistance: The use of stainless steel bellows seals and graphite gland packings allows operation at temperatures up to 400 °C.
  • Wide Range of Nomenclature: Nominal diameters from DN15 to DN500 for systems with pressures PN16–40 and ANSI150–300.
  • Integration with APCS: Full compatibility with PREMIO, PACO electric actuators and ARI-DP pneumatic actuators, equipped with positioners for precise control.

ARI-STEVI Series: Globe and Three-Way Control Valves

The ARI-STEVI valve line features globe and three-way models designed for mixing and diverting flow tasks. Bodies made of high-strength grades of cast iron and cast steel are resistant to thermal stresses. Valves of this series are effectively used for controlling flows of superheated steam, deionized water, aggressive chemical media, refrigerants, and thermal oils.

ARI-PREDU: Self-Operated Pressure Reducing Valves (Downstream)

PREDU series direct-acting diaphragm regulators are designed for automatic maintenance of a set pressure at the valve outlet (downstream). The highly sensitive diaphragm instantly reacts to fluctuations in the working medium pressure, adjusting the flow area of the closure to stabilize the system.

ARI-PREDEX: Self-Operated Pressure Regulating Valves (Upstream)

PREDEX models function as pressure regulating valves (upstream), ensuring stabilization of pressure at the valve inlet. The device is equipped with a diaphragm chamber that controls the valve's opening degree proportionally to the inlet pressure. Both series (PREDU/PREDEX) are optimal for steam, gas, and liquid systems with relatively stable flow rates.
