Viking J-2 Halar Coated Flow Control Valve: Advanced Fire System Protection

The Viking J-2 Halar® Coated Flow Control Valve series provides precise and reliable water regulation for crucial commercial and industrial fire protection systems. Engineered as a quick-opening, differential diaphragm flood valve, it delivers dependable manual or automatic on/off control. This valve is essential for managing water flow and regulating pressure in deluge, pre-action, and automatic tank-filling applications, especially in high-risk, corrosive environments.

• Superior Halar® (ECTFE) Coating: Both the body and cover are coated inside and out with Halar®, a high-performance fluoropolymer. This coating offers exceptional resistance to a wide range of corrosive chemicals, solvents, and saltwater, surpassing the performance of standard epoxy or Kynar coatings. It also boasts mechanical strength, toughness, high thermal stability, and high dielectric strength. This makes the valve ideal for demanding environments such as offshore platforms, chemical facilities, and coastal regions.
• Quick-Opening Differential Design: Featuring a spring-loaded floating clapper and a rolling diaphragm, the valve ensures rapid activation and consistent performance during fire suppression scenarios, facilitating swift water delivery.
• Versatile Installation & Connectivity: These valves accommodate various system architectures with multiple connection options and can be installed in either horizontal or vertical positions, offering flexibility to suit specific piping layouts.
• Flexible Detection Compatibility: The J-2 valve is fully compatible with hydraulic, pneumatic, and electric release systems, allowing for seamless integration into diverse fire safety strategies.
• Simplified Maintenance: Engineered for efficiency, the valve can be reset without being opened and can be trimmed for automatic remote resetting. Internal components, including the diaphragm and seat rubbers, are field-replaceable to minimize downtime.
• Enhanced Component Durability: Beyond the Halar® coating, internal operating parts feature specialized plating to further minimize wear and extend service life in demanding atmospheres.
• Technical Specifications and Compliance Certifications: The valve is UL Listed and FM Approved, meeting rigorous industry benchmarks for reliability.
• Regulatory Adherence: Fully compliant with NFPA standards for fire protection installations, ensuring system integrity and effectiveness.
• Pressure Ratings: Rated for a maximum working water pressure of 250 PSI (17.2 bar) and factory tested to 500 PSI (34.2 bar).

By incorporating these robust flow control valves into your fire safety infrastructure, you ensure long-term durability and operational readiness. Their superior corrosion resistance and precise regulation capabilities protect valuable assets and safeguard personnel in even the most challenging industrial environments. The Viking J-2 valve's ability to maintain consistent sprinkler performance and prevent water surges or pressure drops is critical for reliable fire protection.
