ARI Armaturen – Valves for Industrial & Marine Applications
Johnson Valves are proud to be in partnership with ARI Armaturen to supply their high quality industrial control valves, isolation valves, safety valves, steam traps and strainer for industrial and chemicals processes through to shipbuilding.
ARI valves are manufactured in Germany to a high standard and are supplied to many countries around the world, established in 1950, the privately owned ARI Group employs a staff of more than 1000.

ARI STEVI Control Valves

ARI FABA Isolation Valves
ARI STEVI® Vario 448 / 449 Compact Control Valves
The STEVI Vario is a variable, compact control valve for universal applications. It is based on a modular system, which means that the configuration is adaptable to the task at hand.
• Optimum handling: actuator can be rotated 360°.
• Flexible: changeable, variable trim (at least 4 Kvs values as well as multiple flow characteristics and plug designs).
• Precise and durable: vibration is prevented even at high differential pressures (stable shaft guiding).
• Easy handling: small footprint and reduced weight (low height).
• Economical: very low air consumption (smaller pneumatic actuators possible).

ARI CONA-S® Ball Float Steam Traps
The CONA-S is a float type steam trap for draining condensate in steam lines. This steam trap is capable of draining large capacities of condensate and is well adapted to the changes in flow rates. Used in many steam applications including heat exchangers, autoclaves and condensers.
• Back pressure-free condensate discharge even at extreme pressure and quantity fluctuations.
• Robust and insensitive to water-hammer.
• Union for recovery pipe and bypass possible.
• The controller maybe changed without disturbing the pipe work.
• Controller with integrated automatic ventilation (except 630).
