Datasheet and documents

Description

ARI-PREsys® Overview:

  • Pressure Reducing Stations (PRS) are self-acting or equipped with electro-pneumatic control.
  • Available models:
    • ARI-PREsys®-S (for steam)
    • ARI-PREsys®-W (for water)
    • ARI-PREsys®-A (for air)


Key Features:

  • Compact design: Easy installation with clear setup instructions.
  • Maintenance-free design using stainless steel bellows.
  • Process security: Utilizes harmonized components to ensure stable operation.
  • Pressure-secure subassembly: Built to guarantee safety.
  • Dry and clean process steam: Optionally includes a steam drier.
  • Bypass pipe for emergency operation: Ensures continued function even during maintenance.
  • Condensate drain option on the minimum pressure side.
  • Wall or floor brackets for installation.


Pressure Reducing Station Models:

  1. PRS-S: Basic design for steam, self-acting.
  2. PRS-S Plus: Includes condensate drain on the P2 side.
  3. PRS-S Complete: Comes with complete equipment, including a steam drier, bypass, and full condensate drains.
  4. PRS-W and PRS-A: Models designed for water and air, respectively, also available in complete versions.


Pressure-Temperature Ratings:

  • The pressure-temperature chart provides operational limits, which depend on the materials used and temperature.
  • For example:
    • EN-JL1040 (Cast Iron) operates at 16 bar max at 50°C, dropping to 9.6 bar at 350°C.
    • 1.0619+N (Carbon Steel) operates at 40 bar max at 50°C, dropping to 24 bar at 350°C.


Applications:

  • The pressure reducing stations are primarily used to reduce a higher input pressure to a lower, safe output pressure.
  • The system is ideal for industrial steam, air, and water systems, providing stable pressure reduction without the need for auxiliary power.


Technical Data:

  • The pressure reducing valves come in multiple sizes with Kvs values ranging from 3.2 m³/h for small sizes (DN15) to 125 m³/h for larger sizes (DN100).
  • The stations can be designed with various control methods, including self-acting control or electro-pneumatic control for more precision.


System Design Options:

  • The system offers customizable designs with options such as bypass pipes, condensate drains, and specific valve materials based on the application (e.g., EN-JL1040, EN-JS1049, 1.4408 for stainless steel components).
