Parker launches Viking Xtreme ISO valves for harsh environments

Industrial automation and mobile electrification require components that can withstand increasingly demanding operational environments.

Across sectors such as railway transit, agriculture, and oil and gas, modern machinery relies on robust pneumatic control systems to ensure consistent, uninterrupted performance. Addressing these complex engineering challenges head-on, Parker Hannifin, a Fortune 250 global leader specialising in motion and control technologies, has announced the launch of its new Viking Xtreme ISO valve series. This compact, ISO-standard subbase valve platform is specifically engineered to handle the rigours of general, mobile-related, and harsh industrial applications.

To maximise installation flexibility and operational performance, engineers can deploy these valves in varied configurations to suit their specific infrastructure. Key installation and operational features include:

• The ability to install the valve on a single subbase or integrate it into a stackable manifold.

• Stackable manifold installations that effectively support pressure zoning within centralised applications.

• Internal or external pilot configurations that can be conveniently adjusted in the field to meet precise application requirements.

Advanced Core Technology for Extreme Conditions

At the core of this newly launched platform is Parker’s advanced over-moulded spool technology. This specific engineering choice supports a long service life, broad operating capabilities, and a reliable, high-performance output even under continuous strain. The bi-directional, over-moulded spool is designed to function seamlessly in extreme temperatures, operating efficiently from -40°C to +70°C (-40°F to +158°F). In addition to its impressive temperature resilience, the system accommodates an operating pressure range that spans from a vacuum up to 10 bar. For pneumatic remote pilot variants, this pressure threshold extends even further to 16 bar. The platform also boasts exceptional flow performance, delivering flow rates ranging from 540 Nl/min (0.55 Cv) up to a substantial 5900 Nl/min (6.01 Cv).

Mobile-related applications and harsh environmental conditions present unique threats to machinery, notably through constant vibration, sudden impacts, and corrosive external elements. To combat these recurring issues, the Viking Xtreme ISO valve series offers various solenoid voltages paired with either standard or mobile-rated coils, alongside remote pilot valve options. The mobile versions of this valve have successfully passed rigorous shock and vibration testing, comprehensively meeting the stringent IEC 6173:1999, category 1, class B standards.

To further protect against corrosion in highly challenging and exposed settings, the valves incorporate durable materials throughout their entire construction. Essential durability features include:

• The strategic utilisation of stainless steel for end fasteners, internal springs, and solenoid armatures.

• An impressive salt spray qualification that exceeds 1000 hours of continuous testing.

• A robust construction that fully supports operation in demanding salt spray applications.

Strategic Consolidation for Machinery Design

These modern advancements allow plant managers and machinery designers to rethink their pneumatic infrastructure entirely. The new series is explicitly designed to help operators consolidate their existing ISO non-plug-in valve inventories. Depending on the specific application, the versatile platform may enable a one-size reduction. This potential downsizing can significantly help to lower overall operational costs, reduce footprint dimensions, and decrease equipment weight, all without sacrificing the required system performance.

Speaking on the strategic launch of this robust new platform, Patrick Berdal, European Product Manager for Controls within the Electric Motion & Pneumatic Division at Parker Hannifin, highlighted the industry's constantly evolving needs.

“Customers are looking for compact, reliable pneumatic valve solutions that help simplify machine design while performing in demanding operating conditions,” said Berdal. “The Viking Xtreme ISO valve series reflects Parker’s commitment to engineering solutions that improve productivity, uptime, and operational efficiency for customers across key industrial and mobile markets.”.

As a fundamental part of the broader Motion Systems Group, Parker's Electric Motion and Pneumatic Division continues to design and manufacture components that actively improve system safety, efficiency, and performance across both heavy industrial applications and modern mobile electrification.
