Safety valve - SAFE | ARI

The ARI-SAFE Safety Valve is designed for optimal performance in industrial systems, ensuring safety and reliability. It features both full lift (D/G) and standard (F) safety valve types, with TÜV-certified approvals according to DIN EN ISO 4126-1, AD2000-A2, and TRD 421 standards. The valve is spring-loaded and direct-loaded, with a wear-resistant seat/disc for enhanced durability. It offers precision alignment for smooth operation and includes options for soft seal discs and EPDM or stainless steel bellows. Common thread types are available for diverse applications. Technical specifications include nominal pressures of PN16, PN25, and PN40, with materials such as EN-JL1040, EN-JS1049, 1.0619+N, and 1.4408 stainless steel. The valve operates within a temperature range of -60°C to +450°C and features standard DIN EN 1092-1 flange connections. It is available in nominal diameters from DN15 to DN350, with spring ranges from 0.2 bar to 40 bar. Additional features include lift forks, levers, optional bellows for high-pressure sealing, balanced pistons, and sealing rings made of pure graphite or CuFA materials. These valves are ideal for steam, air, and water systems, playing a crucial role in pressure regulation and preventing overpressure scenarios in industrial applications.

Sizing and Application
:

  • Capacity: The valve's capacity depends on the medium (steam, air, water) and the set pressure.
  • Medium Details: Calculations are based on the mass flow, molar mass, temperature, set pressure, and back pressure.
  • Back Pressure: Can be superimposed (no back pressure allowed on request) or built-up (max. 10% from set pressure, higher on request).


Valve Sizes
:

  • Nominal Diameters (DN): Available from DN15 up to DN350, depending on the application.
  • Spring Range: The valves are available in various spring ranges for different pressures, from 0.2 bar to 40 bar.


Additional Features
:

  • Lift Fork and Levers for operation.
  • Bellows (optional) for sealing at high pressures.
  • Balanced piston for some models.
  • Sealing Rings: Pure graphite or CuFA materials for better sealing.


Applications
:

  • These valves are used in steam, air, and water systems and are ideal for pressure regulation in industrial systems.
  • They are critical in maintaining safe operating pressures and preventing overpressure scenarios.
