Protect your commercial and industrial facilities with the Viking J-2 Halar Coated Flow Control Valve. This quick-opening differential diaphragm valve delivers precise manual or automatic control for deluge, pre-action, and automatic tank-filling systems in high-risk environments.

Engineered to meet strict life safety demands, this valve satisfies NFPA installation standards for fire protection systems. It integrates smoothly with hydraulic, pneumatic, and electric release strategies, ensuring reliable water regulation and rapid activation during a fire suppression event.

  • Halar® (ECTFE) Coating: The body and cover feature an interior and exterior fluoropolymer coating that resists corrosive chemicals, solvents, and saltwater.
  • Quick-Opening Design: A spring-loaded floating clapper and rolling diaphragm provide rapid activation during fire suppression events.
  • High-Pressure Handling: The unit handles a maximum working water pressure of 250 PSI (17.2 bar) and undergoes factory testing up to 500 PSI (34.2 bar).
  • Flexible Installation: You can install this valve in either horizontal or vertical piping layouts to suit your specific facility requirements.
  • Simplified Maintenance: Specialized plating on internal parts minimizes wear in harsh atmospheres, while field-replaceable diaphragm and seat rubbers simplify ongoing upkeep.
  • Efficient Resetting: The unit resets without opening, and you can trim it for automatic remote resetting to reduce system downtime.
